Statements: 1. Class A has a higher enrollment than Class B. 2. Class C has a lower enrollment than Class B. 3. Class A has a lower enrollment than Class C. If the first two statements are true, the third statement is:
Correct answer: B. False
- A. True
- B. False
- C. Uncertain
- D. None of these
Explanation
The first two statements establish the enrollment order: Class A > Class B > Class C. Therefore, Class A has the highest enrollment. The statement "Class A has a lower enrollment than Class C" directly contradicts this and must be false.
