Question #1
Read the paragraph and answer the question using only the information given. No informant who was paid in advance was called as a witness at trial. Some informants who were called as witnesses had prior convictions. All informants interviewed on Monday were paid in advance. Which of the following must be true?
Correct answer: A
Explanation
All Monday informants were paid in advance, and no informant paid in advance was called as a witness, so no Monday informant was called. The other statements go beyond the paragraph: it says nothing about Monday informants and prior convictions, and it does not say that unpaid informants or those with convictions were all called.

Question #2
An agent is drafting a section of a report and wants every sentence to be grammatically correct and clear. Which of the following sentences uses parallel structure correctly?
Correct answer: B
Explanation
Items in a series must share the same grammatical form. Only the correct sentence uses three -ing verb phrases. The other sentences mix an infinitive, a noun phrase or both with -ing forms, which breaks the parallel structure.

Question #3
An agent working on an active investigation receives a call from a newspaper reporter who asks whether a named local business owner is a suspect. Which of the following is the MOST appropriate response by the agent?
Correct answer: C
Explanation
Statements about an open case should come through the office authorized to speak for the agency. Referring the reporter protects the investigation and the owner's reputation. Confirming status, hinting that a review exists, or alerting the owner can all compromise the case.

Question #4
Two agents are reviewing 144 case files. Agent Ruiz reviews 12 files per hour and begins 2 hours before Agent Cole, who reviews 8 files per hour. Once Cole begins, both work without a break at their steady rates until all 144 files are reviewed. How many hours does Ruiz work in total?
Correct answer: C
Explanation
In the first 2 hours Ruiz reviews 12 x 2 = 24 files, leaving 120. Together they review 12 + 8 = 20 files per hour, so the rest takes 120 / 20 = 6 hours. Ruiz works 2 + 6 = 8 hours. The value 6 is only Cole's time, and 7.2 comes from dividing 144 by 20 and ignoring the head start.

Question #5
Passage: Every surveillance report filed this month was reviewed by a supervisor. A report that a supervisor reviewed was either approved or returned to the agent who wrote it. No returned report was sent to the U.S. Attorney's Office. Some reports filed this month concern firearms trafficking. Based only on the information in the passage, which of the following must be true?
Correct answer: D
Explanation
All reports filed this month were reviewed, and every reviewed report was approved or returned. Some filed reports concern firearms trafficking, so at least one of them was approved or returned. The passage never says approved reports were sent on, and 'no returned report was sent' does not mean every unsent report was returned. The passage also gives no information about which firearms reports were returned.

Question #6
During a three-day surveillance operation, your team agreed to radio a status check every two hours. On the second day, the location has been quiet for six hours and your partner says the checks are no longer needed. What should you do?
Correct answer: A
Explanation
Dependability means keeping the procedures the team agreed to, even when conditions make them feel unnecessary. The team relies on regular reports to know that you are alert and safe. Changing the interval or the trigger on your own, even with a log entry, breaks the agreement without the team's consent.

Question #7
You and another agent drove to an out-of-town interview in the same vehicle and returned the same evening. Later you see that his travel voucher claims a hotel night for the trip. Which action is MOST appropriate?
Correct answer: B
Explanation
Knowledge of a likely false claim for government funds must go to someone with the authority to review it. Handling it privately or informally leaves the decision with a peer, and waiting for a pattern lets the claim stand. Discussing it with other agents spreads an accusation without addressing it.

Question #8
Which of the following sentences is the clearest and most grammatically correct for use in an official investigative report?
Correct answer: A
Explanation
The correct sentence has one subject performing two parallel actions, placed and recorded. One option has a dangling modifier because the inventory form did not complete the search. Another is a comma splice joining two independent clauses, and the last breaks parallel structure by pairing a past-tense verb with an -ing phrase.

Question #9
A task force must review 424 financial records. Analyst Reyes begins alone and reviews 14 records per hour. Two hours later, Analyst Okafor joins and reviews 22 records per hour, and both continue at those rates until all records are reviewed. How many hours after Reyes began is the review finished?
Correct answer: C
Explanation
In the first 2 hours Reyes reviews 14 x 2 = 28 records, leaving 396. Together they review 14 + 22 = 36 records per hour, so the remainder takes 396 / 36 = 11 hours. The total from Reyes's start is 2 + 11 = 13 hours. The trap is answering 11, which counts only the time after Okafor joined.

Question #10
A Special Agent is writing the narrative section of a surveillance report that a prosecutor may read. The agent personally watched the suspect leave 410 Alder Street at 3:15 p.m. Which sentence is MOST appropriate for the report?
Correct answer: A
Explanation
A report should state what the writer personally saw, with exact time, place and description, and no conclusions the writer cannot support. The correct sentence does this in the first person. Saying the bag held the firearms, calling the sedan his, or describing the bag as heavy adds facts the agent did not observe, and the passive sentence with a vague time loses the precision a prosecutor needs.
