"The alphanumeric coding of a fingerprint is a systematic description of the main patterns on the print. Within a certain metropolitan district, 90% of the population have fingerprints that can be alphanumerically coded. - CORRECT ANSWER=> A) Can be alphanumerically coded, with a probability of 10% B) Can be alphanumerically coded, with a probability of less than 90% C) Cannot be alphanumerically coded, with a probability of 10% D) Cannot be alphanumerically coded, with a probability of up to 90% E) May be coded alphanumerically, but the probability is unknown Answer: C - We know from the second sentence that 90% of the people in this district have fingerprints that can be coded. Therefore, we know that 10% (100%-90%=10%) have fingerprints that cannot be coded. Given this information, the chance of selecting a person from this district with fingerprints that can be coded is 90% and the chance of selecting a person from this district with fingerprints that cannot be coded is 10%. Response A is incorrect because a probability of 10% is an underestimate of the probability that the fingerprints of a person from this district can be coded. Response B is incorrect because, like response A, it is an underestimate. Response D is incorrect because it is an overestimate of the probability that the fingerprints of a person from this district cannot be coded. Response E is incorrect because the probability that the fingerprints can be coded is known to be 90%."
"Twenty-five percent of the nation?s incoming cargo containers are shipped to the port of Cary, and 10% are shipped to the port of Davidson. Merchandise that arrives at these ports in containers is shipped by truck and rail to its final destination in the United States. Cary is one of the biggest targets for cargo thieves due to the large volume of merchandise shipped there. - CORRECT ANSWER=> A) There is a 75% chance that the container was not shipped to the port of Cary B) There is a 25% chance that the container was shipped to the port of Davidson C) There is a 75% chance that the container was shipped to the port of Davidson D) There is a 25% chance that the container was not shipped to the port of Davidson E) There is a 90% chance that the container was shipped to the port of Cary Answer: A - According to the first sentence, 25% percent of the nation?s incoming cargo containers are shipped to the port of Cary. This means that 75% of the nation?s incoming cargo containers are not shipped to the port of Cary. Therefore, there is a 75% chance that a container taken at random was not shipped to the port of Cary. Responses B and C are incorrect because there is a 10% chance that the container was shipped to the port of Davidson. Response D is incorrect because there is a 90% chance that the container was not shipped to the port of Davidson. Response E is incorrect because there is a 25% chance that the container was shipped to the port of Cary." "Staff at a law enforcement training academy purchases badges at $32 each for all the graduates of the academy. The last training class graduated 25 new officers. What is the total amount of money the academy staff will spend for the badges for these new officers, if the badge vendor provided the Academy a 20% discount on each badge? - CORRECT ANSWER=> A) $ B) $ C) $ 640 D) $ E) None of these
B) 8 1/
C) 4 4/
D) 6 3/
E) None of these Answer: C - Let Officer Kay's hours be represented by 1/8 and Officer Ming's hours be represented by 1/10. This reframes the data, indicating that Officer Kay completes 1/8 of the job per hour and Officer Ming completes 1/10 of the job per hour. Together, they work 1/8 + 1/10 = 18/80 of the job per hour, which, when reduced to its lowest terms, is 9/40.Therefore, if T is the amount of time it takes the two of them to finish the job, then 9/40 of the job x T (expressed in hours) has to equal 1 job. So, (9/40) x T = 1, therefore T= 1/(9/40), or T = 40/9. This means it would take 4 and 4/9 hours (about 4 hours and 27 minutes) for Officers Kay and Ming to complete the task together." "There are three dogs in a canine team in charge of inspecting cargo at an international airport for prohibited fruits, vegetables, and meats. Last week, one of these dogs identified 20 cartons of prohibited fruit among 120 total cartons on a flight arriving from overseas. Assuming that the dog selected the first carton to be inspected totally at random, what was the probability that this carton contained a shipment of prohibited fruit? - CORRECT ANSWER=> A) 1/ B) 1/ C) 1/ D) 1/ E) None of these Answer: D - Twenty cartons out of 120 total cartons contained prohibited fruit. Therefore, if you randomly selected one carton from the 120 cartons, the probability of selecting one of the prohibited cartons of fruit is 20 out of 120 or 20/120 = 1/6." "One day, Officer Ferong spent 4 hours processing passengers from a flight from Brazil at a rate of 16 passengers every 40 minutes. The next day, she spent 4 hours processing passengers at a
rate of 18 every 40 minutes. What was the average number of passengers she processed during these two 4- hour periods? - CORRECT ANSWER=> A) 283 B) 204 C) 141. D) 102 E) None of these Answer: D - 16/40 = .40 (this says Officer Ferong processed passengers at a rate of .40 per minute on the first day); .40 x 60 = 24 passengers per hour; and 24 x 4 = 96 passengers every four hours. For the next day, the calculations are 18/40 = .45 x 60 = 27 x 4 = 108. The average of 108 and 96 is 108 + 96? 2 = 102." "Once a request to carry firearms into a foreign country are approved, a CBP Officer must notify the Office of Foreign Operations for coordination of the request. - CORRECT ANSWER=> A) Change to carry to for carrying B) Change are to is C) Change coordination to coordinating D) No correction is necessary Answer: B - A verb must agree with its subject in number. The subject, "request," is singular and, therefore, the verb should be changed from "are" to "is."" "Supervisor Smith knows that it is important for his CBP Agriculture Specialists to understand each of the fundamental principals that apply to all methods of dog training. - CORRECT ANSWER=> A) Change knows that to knows which B) Change each to each and every one C) Change principals to principles D) No correction is necessary
C) The impact of this training requirement will be measured by the number of new CBP Officers which successfully complete the probationary period. D) The impact that this training requirement has will be measured by the number of new CBP Officers which successfully complete the probationary period. Answer: A - The correct answer is (A). The sentence should read as follows: The impact of this training will be measured by the number of new CBP Officers who successfully complete the probationary period. This is a well-constructed sentence in both grammar and syntax." "Sentence which is correct in grammar, syntax, punctuation, and spelling and which exemplifies usage suitable to a formal letter or report - CORRECT ANSWER=> A) The alien‟s use of a fraudulant document was a hindrance to the identification of the alien B) The alien‟s use of a fraudelant document was a hindrence to the identification of the alien C) The alien‟s use of a fraudulent document was a hindrance to the identification of the alien. D) The alien‟s use of a fraudelent document was a hindrance to the identification of the alien. Answer: C - The words "hindrance" and "fraudulent" are spelled correctly in this sentence while various incorrect spellings of these words are used in A, B, and D." "(1) First used on a wide scale in 1970, narcotic detector dogs save countless staff hours in locating narcotics in vehicles, mail, unaccompanied baggage, and on cargo ships. A dog and its handler can check 500 packages in 30 minutes; it would take a mail examiner several days to inspect as many. At border ports, a dog can inspect a vehicle in about two minutes; the same search by a CBP Officer would take at least 20 minutes. Therefore, the use of narcotic detector dogs has greatly enhanced the fight against illegal drug smuggling into the United States.(2) While not exactly high-tech, a unique tool in CBP?s drug fight is its force of narcotic detector dogs, their trainers, and the CBP Officers who work with these canine detectors.(3) This fight continues today, extending into the high-tech world of the 21st Century. Through diligence, close inspection, sophisticated technology, and the sacrifice of lives, CBP has giv - CORRECT ANSWER=> A) 4 - 3 - 2 - 1 B) 3 - 4 - 1 - 2 C) 2 - 3 - 4 - 1
D) No correction is necessary Answer: A - The most logical order of the passages is 4, 3, 2, 1. It is not logical to begin the passages with paragraphs 2 or 3, as indicated in Responses B and C, because they appear to complete information that has been presented earlier and, therefore, depend on information in the other two paragraphs in order to be understood. This also eliminates Response D. This leaves Response A, which begins with paragraph 4. The paragraphs presented in this order form a well-organized, coherent passage." "(1) Project Shield America will have two operational components. The first will be to reach out and form partnerships with U.S. manufacturers and distributors of the sensitive technology, weapons, and equipment sought by terrorists. The second will be to investigate and halt those attempting to acquire and illegally export weapons components to groups intent on harming America.(2) Beginning immediately, field offices will identify the specific U.S. firms in their areas that manufacture or distribute materials of interest. Agents will then visit these firms and provide them with materials about Project Shield America, information about U.S. export controls, and data about the items sought by terrorists. Most importantly, the agents will encourage these firms to notify agents if they are approached by customers looking to acquire and export their products illegally.(3) In sum, under the banner of Project Shield America - CORRECT ANSWER=> A) 1 - 4 - 2 - 3 B) 1 - 4 - 3 - 2 C) 1 - 2 - 4 - 3 D) No correction is necessary Answer: C - The most logical order of the passages is 1, 2, 4, 3. The first paragraph introduces Project Shield America and defines the two operational components of the project. Accordingly, paragraph 1 should be the first paragraph. Paragraphs 2 and 4 elaborate on the two operational components of the project introduced in paragraph 1 and therefore must follow paragraph 1. Paragraph 2 logically comes before paragraph 4 because paragraph 2 elaborates on the first operational component of the project whereas paragraph 4 elaborates on the second operational component. Finally, paragraph 3 is clearly the concluding paragraph because it provides a summation and closing for the entire passage. The paragraphs presented in this order form a well-organized, coherent passage."
Answer: C - Combining the information in the last two sentences we know that if it is a holiday weekend, then special funding is needed from the city council (due to assigning additional staff to duty). Accordingly, if special funding is not needed, then it must not be a holiday weekend; otherwise, special funding would be needed.Responses A and E are false because they contradict the information in the paragraph. Responses B and D might be true, but they are not fully supported by the paragraph." "Several different means of smuggling, such as cross-border tunnels, are used to bring narcotics, individuals, and contraband into the United States. Cross-border tunnels can be found all along the land border of the United States. They vary significantly in size and complexity of construction, although most are crudely constructed. Further, most crossborder tunnels are used for smuggling narcotics, although illegal aliens and other contraband have also been smuggled using tunnels. - CORRECT ANSWER=> A) Most cross-border tunnels are not skillfully constructed B) All cross-border tunnels are used for narcotics smuggling C) At least some cross-border tunnels are not free from narcotics smuggling D) At least some of the means used for narcotics smuggling are cross-border tunnels E) At least some means used for narcotics smuggling involve crudely constructed tunnels Answer: B - This is an example of a test question with a negative lead statement. It asks for the conclusion that is NOT supported by the paragraph. That means that four of the statements are valid conclusions based on the paragraph while one is not. In this case, Response B is invalid. The paragraph says that "most" cross border tunnels are used for smuggling narcotics, but Response B says that "all" cross border tunnels are used for smuggling narcotics.Responses C and D are based on the information that most cross border tunnels are crudely constructed. Response C is based on the information that most cross border tunnels are used to smuggle narcotics. Finally, Response E combines all information about the tunnels being crudely constructed and used for smuggling narcotics." "Naturalized U.S. citizens can lose their U.S. citizenship if and only if they expatriate or are denaturalized. Misrepresentation on a legal permanent residence application, certain crimes, and leaving the United States within one year of naturalization to establish permanent residence elsewhere are all grounds for denaturalization. P.C. is a naturalized U.S. citizen. -
CORRECT ANSWER=> A) If P.C. loses her U.S. citizenship without being denaturalized, then she must have expatriated B) If P.C. does not expatriate, then she cannot lose her U.S. citizenship C) If P.C. is denaturalized, then she must have made a misrepresentation on her legal permanent residence application D) If P.C. has committed no crimes, then she cannot be denaturalized E) P.C. cannot lose her U.S. citizenship without being denaturalized Answer: A - This question concerns a situation where there are two ways for naturalized U.S. citizens to lose U.S. citizenship, either by expatriation or denaturalization. In Response A, the situation is considered in which P.C. has lost her U.S. citizenship without being denaturalized. Expatriation is the only option remaining to explain the loss of U.S. citizenship.Responses B and E are invalid because they fail to consider that there is more than one way for P.C. to lose U.S. citizenship. Responses C and D are about situations in which P.C. may or may not be denaturalized. These two responses are invalid because they fail to consider that there are several possible reasons for denaturalization." "Following the Vietnam War, many people from Southeast Asia were paroled into the United States with an indefinite immigration status. In 2003, a new rule was developed to allow for adjustment of immigration status for some of these people. According to the new rule, all nationals of Vietnam (and some others, for example, nationals of Cambodia) who were paroled into the United States through the Orderly Departure Program were eligible to apply for permanent resident status. - CORRECT ANSWER=> A) Everyone eligible to apply for permanent resident status is a national of Vietnam who was paroled into the United States through the Orderly Departure Program B) No one ineligible to apply for permanent resident status was a national of Vietnam who was paroled into the United States through the Orderly Departure Program C) Only nationals of Vietnam who were paroled into the United States through the Orderly Departure Program were eligible to apply for permanent resident status D) Some nationals of Vietnam who were paroled into the United States through the Orderly Departure Program were ineligible to apply for permanent resident status
Answer: C - This question asks for the response option that CANNOT be validly concluded from the information in the paragraph. The only response option that cannot be validly concluded is Response C. Response C is invalid because the paragraph does not say that employers must refuse acceptance of documentation that appears to be true and relevant.Responses B and E are valid based on the information in the first sentence. Response A is valid based on the information in the second sentence that employers cannot change documentation requirements. Response D is valid based on the information in the last sentence stating that employers may request different documentation when they believe the documentation submitted appears to be altered." "Although the owner of a certain farm said that all her Central American (for example, Salvadoran and Honduran) workers were working legally, officers discovered that many of the farm's employees were not authorized to work in the United States. After checking the employees' documentation, officers discovered that all of the female employees were working in the United States legally and none of the illegal workers were from Honduras. - CORRECT ANSWER=> A) All of the employees from Honduras were working legally B) Some of the women were illegal workers C) None of the employees from Honduras were female D) Some of the female employees were from Honduras E) All of the Salvadoran employees were women Answer: A - The correct answer is A. The last sentence of the paragraph states that none of the illegal workers were from Honduras, which is equivalent to saying that none of the employees from Honduras were working illegally. Given that none were working illegally, it must be the case that all were working legally.From the information in the paragraph, we know that all of the female employees were working legally and that all of the employees from Honduras were working legally. However, there is insufficient information to determine how many of the female employees were from Honduras. Therefore, Responses C, D, and E cannot be validly concluded. Response B contradicts the information that all of the female employees were working legally." "The two ways of acquiring U.S. citizenship at birth are by place of birth and inheritance from U.S. citizen parents. Any child born in the United States while under U.S. jurisdiction is a U.S. citizen at birth. Because foreign ambassadors are not subject to U.S. jurisdiction, children born in the United States to foreign ambassadors do not obtain U.S. citizenship at birth. Children
born overseas to U.S. citizen parents derive U.S. citizenship at birth, as long as the parents previously lived in the United States for a sufficient period of time. All others must naturalize to become citizens. J.B. was not a U.S. citizen at birth. Which of the following conclusions can be drawn about J.B.? - CORRECT ANSWER=> A) Was born in the United States B) Was born overseas to U.S. citizen parents C) Was not born in the United States to U.S. citizen parents D) Was not born overseas to U.S. citizen parents E) Was born to U.S. citizen parents Answers: C and D - There are two ways of acquiring U.S. citizenship at birth, and J.B. did not acquire U.S. citizenship at birth. Therefore, J.B. did not meet either of the two conditions for acquiring U.S. citizenship at birth. Specifically, J.B. was not born in the United States to U.S. citizen parents, and J.B. was not born overseas to U.S. citizen parents who previously lived in the United States for the required period of time. Any other conclusion is not supported by the information in the paragraph." "In a certain border state, all state peace officers have the authority to issue state citations for misdemeanor marijuana and paraphernalia offenses committed in their presence. Early last year, a certain CBP Sector in the state began a new operation with state police. Under this operation, all sector canine handlers were cross-designated as state peace officers. - CORRECT ANSWER=> A) At least some law enforcement officers who can issue citations for misdemeanor marijuana and paraphernalia offenses committed in their presence are state peace officers B) All sector canine handlers have the authority to issue state citations for misdemeanor marijuana and paraphernalia offenses committed in their presence C) At least some individuals who have the authority to issue citations for misdemeanor marijuana and paraphernalia offenses committed in their presence are sector canine handlers D) No sector canine handlers lack the authority to issue state citations for misdemeanor marijuana and paraphernalia offenses committed in their presence
E) If C.P. has veterans' preference, then C.P. is eligible to apply for any open civil service examination Answer: E - The fourth sentence in the paragraph states that when an applicant has veteran's preference, the applicant has permanent reinstatement eligibility. The second sentence states that an applicant with reinstatement eligibility is eligible to apply for any civil service examination. Therefore, if an applicant has veteran's preference, the applicant is eligible to apply for any civil service examination due to having reinstatement eligibility. Accordingly, Response E is valid because C.P. will be eligible to apply for any open civil service examination if C.P. has veterans' preference. Responses A, B, C, and D are invalid because they make assumptions which cannot be supported by the information in the paragraph. Response B assumes that the only two ways of attaining reinstatement eligibility is to have veteran's preference or three years creditable service. Response C assumes that applicants are allowed to apply for open civil service examinations and jobs open only to status candidates only when applicants have reinstatement eligibility. Responses A and D assume" "When officers must physically force entry into a home, they are required to ensure that the home is in a secure condition when they leave. Failure to secure the home leaves the officers liable for loss of items from the home and/or damage to the home that results from leaving the property unsecured. It is legal to break down doors in order to gain entry, if that degree of force is determined by an officer to be necessary. If an officer forces entry, the officer is required to take measures to minimize damage to the property. Officer Stoler needs to gain entry into a suspect's home. - CORRECT ANSWER=> A) Officer Stoler is required to minimize damage to the home if Officer Stoler forces entry B) If Officer Stoler is not required to ensure that the home is secure upon leaving, then Officer Stoler did not force entry into the home C) If Officer Stoler forces entry and fails to secure the home, Officer Stoler may be liable for loss of items resulting from leaving the home unsecured D) If Officer Stoler must physically force entry into the home, then Officer Stoler is not required to ensure that the home is secure upon leaving E) Officer Stoler will be required to secure the home unless Officer Stoler does not force entry
Answer: D - This question is a negative lead question, so the correct response is the only response option that CANNOT be validly concluded. The first sentence in the paragraph states that when officers must physically force entry into a home, the officers are required to ensure that the home is in a secure condition when the officers leave. Response D contradicts this information in saying that Officer Stoler is not required to leave the home in a secure condition. Thus, Response D is the correct response. Response A is valid and follows from the information in the fourth sentence. Responses B and E are valid and follow from the information in the first sentence. Response C follows from the information in the third sentence and is valid." "Recently, officers received leads from informants about possible illegal activity at La Rosita Park. When officers arrived at the park, they drove through the parking lots, looking for individuals and vehicles matching their leads. The officers examined several suspicious vehicles, including many unregistered vehicles. All of the unregistered vehicles contained bundles of marijuana. No arrests have been made in connection with this incident. - CORRECT ANSWER=> A) Several arrests have been made in connection with this incident B) Some of the vehicles that did not contain bundles of marijuana were unregistered C) All of the vehicles that contained bundles of marijuana were unregistered D) All of the vehicles that did not contain bundles of marijuana were registered E) Some of the vehicles that contained bundles of marijuana were registered Answer: D - The fourth sentence contains the information that all of the unregistered vehicles contained bundles of marijuana. Accordingly, if a vehicle did not contain bundles of marijuana, it could not be one of the unregistered vehicles since all unregistered vehicles contained marijuana. Therefore, it can be deduced that all of the vehicles that did not contain bundles of marijuana were registered. Response A contradicts the information in the last sentence. Response B contradicts the information in the fourth sentence. Response C assumes that only unregistered contained bundles of marijuana, but there is insufficient information to make that conclusion. Response E assumes that some of the registered vehicles also contained bundles of marijuana, but there is insufficient information to make that conclusion."
B) If R.G. has violated non-immigrant status but has not remained in the United States longer than permitted, then R.G. has accepted unauthorized employment C) If R.G. has not remained in the United States longer than permitted, R.G. is not an undocumented alien D) If R.G. is an undocumented alien, then R.G. entered the United States legally E) If R.G. is not an undocumented alien, then R.G. has not accepted unauthorized employment Answer: E - Based on the information in the first sentence, if R.G. is not an undocumented alien, then R.G. has not violated his/her nonimmigrant status. Based on the information in the second sentence, if R.G. has not violated his/her non-immigrant status, then R.G. has not accepted unauthorized employment. Therefore, if R.G. is not an undocumented alien, the R.G. has not accepted unauthorized employment, Response E. Responses A and D are invalid because it cannot be determined whether or not R.G. entered the United States illegally based only on the information that R.G. is an undocumented alien because R.G. may have violated his/her non-immigrant status. Response C is invalid because R.G. may be an undocumented alien for several different reasons even if R.G. did not remain in the United States longer than permitted. Likewise, Response B is invalid because R.G. could have committed a violation other than accepting unauthorized employment that resulted in violation of non-immigrant status." "When an illegal alien is being "removed," the alien's passport in U.S. Government possession is returned to the issuing government, not to the illegal alien. If the illegal alien's departure is voluntary, the passport is allowed to be returned to the alien. The U.S. Government holds the passport of H.B., an illegal alien who must leave the country. - CORRECT ANSWER=> A) H.B.'s departure is not voluntary if H.B.'s passport is allowed to be returned to H.B. B) If H.B.'s passport is not returned to the issuing government upon H.B.'s departure, then H.B. is not being removed C) H.B.'s departure is not voluntary unless the passport is allowed to be returned to H.B. D) If H.B.'s passport is not allowed to be returned to H.B., then H.B.'s departure is not voluntary E) If H.B. is being removed, then H.B.'s passport is to be returned to the issuing government
Answer: A - This question is a negative lead question, so the correct response is the only response option that CANNOT be validly concluded. According to the third sentence, if H.B.'s departure is voluntary, then the passport is allowed to be returned to H.B. Based on this information, Response A is invalid. Responses C and D are both valid and are supported by the information in the third sentence that the passport is allowed to be returned to H.B. if H.B.'s departure is voluntary. Responses B and E are valid and are supported by the information in the second sentence that H.B.'s passport will be returned to the issuing government if H.B. is being "removed."" "Oleoresin capsicum (OC), or "pepper spray," is an effective law enforcement tool for incapacitating violent or threatening arrestees without using deadly force. Pepper spray causes a burning sensation of the eyes and skin and tearing and swelling of the eyes. Almost all arrestees are unable to see after being sprayed with OC. Some law enforcement agencies that have adopted OC sprays have fewer allegations of use of excessive force. Many law enforcement agencies have reported a reduction in officer and arrestee injuries as a result of the introduction of OC sprays. - CORRECT ANSWER=> A) Any use of a law enforcement tool that causes a burning sensation of the eyes is considered to be the use of deadly force B) Few arrestees are able to see after being sprayed with OC C) All law enforcement agencies which have reduced officer and arrestee injuries have also reduced allegations of use of excessive force D) No agencies that have adopted OC sprays have fewer allegations of use of excessive force E) Only pepper spray is an effective law enforcement tool for incapacitating violent or threatening arrestees without using deadly force Answer: B - The third sentence says that almost all arrestees are unable to see after being sprayed with OC. Accordingly, few arrestees are able to see after being sprayed with OC, Response B. Response A is false because, according to the first sentence, OC is an example of a tool that causes a burning sensation of the eyes but is not deadly force. Sentences four and five do not say that the agencies who have experienced fewer allegations of use of excessive force are the same agencies that have reported a reduction in officer and arrestee injuries, thus Response C is
