DAA DAA Logical Reasoning and Deductive Thinking 1 — Questions and Answers
Question 1: All officers complete basic training. James is an officer. What can be concluded?
- James has completed basic training (Correct answer)
- James may skip basic training
- James is exempt from training
- Nothing can be concluded
Correct answer: James has completed basic training
Since all officers complete basic training and James is an officer, it logically follows that James has completed basic training.
Question 2: If no snipers are recruits and all recruits wear red berets, which statement must be true?
- No snipers wear red berets
- Some snipers wear red berets
- All snipers wear red berets
- None of the above (Correct answer)
Correct answer: None of the above
Recruits wear red berets, but since no snipers are recruits, we cannot determine whether snipers wear red berets or not — it is not necessarily true that no sniper wears one.
Question 3: A unit deploys only when conditions A and B are both met. Condition A is met. What happens?
- The unit deploys
- The unit does not deploy unless B is also met (Correct answer)
- The unit deploys at half strength
- Condition B is automatically met
Correct answer: The unit does not deploy unless B is also met
Both A and B must be satisfied; meeting only A is insufficient for deployment.
Question 4: Either the convoy travels by road or by air. It does not travel by air. What follows?
- The convoy travels by road (Correct answer)
- The convoy does not move
- The convoy travels by sea
- Nothing can be determined
Correct answer: The convoy travels by road
This is a disjunctive syllogism: when one of two options is eliminated, the other must be true.
Question 5: All armored vehicles are heavy. Some heavy vehicles require special bridges. Which must be true?
- All armored vehicles require special bridges
- Some armored vehicles may require special bridges (Correct answer)
- No armored vehicles require special bridges
- All heavy vehicles are armored
Correct answer: Some armored vehicles may require special bridges
Since some heavy vehicles require special bridges and all armored vehicles are heavy, it is possible — but not certain — that some armored vehicles fall into that subset.
Question 6: If a soldier passes the fitness test, they advance. Private Lee did not advance. What can be inferred?
- Private Lee failed the fitness test (Correct answer)
- Private Lee passed but was held back
- Private Lee did not take the test
- Nothing can be inferred
Correct answer: Private Lee failed the fitness test
By contrapositive: if a soldier did not advance, they did not pass the fitness test.
