Consider the following statements: 1. All supersonic transport aircraft have swept wings. 2. Some swept-wing aircraft are unmanned aerial vehicles (UAVs). Which of the following conclusions logically follows?

(A) All supersonic transport aircraft are UAVs.

(B) Some supersonic transport aircraft may be UAVs.

(C) No swept-wing aircraft is a supersonic transport aircraft.

(D) All UAVs have swept wings.

Answer Key:

B

### 5-Stage Derivation & Analytical Solution: 1. **Stage 1: Set Theory Representation:** Let S = Supersonic transport, W = Swept-wing aircraft, U = UAVs. Premise 1: S ⊆ W. Premise 2: W ∩ U ≠ ∅. 2. **Stage 2: Intersection Possibility:** Since S is a subset of W, S ∩ U may or may not be non-empty. Thus, "Some supersonic transport aircraft may be UAVs" is the only valid modal conclusion. 3. **Stage 3: Conclusion:** Option B is correct.
