Given question has main statement followed by four statements. Choose the ordered pair of statements, where the first statement implies the second, and the two statements are logically consistent with the main statement. The rules are either lenient or fixed

A. The rules are lenient

B. The rules are not lenient

C. The rules are fixed

D. The rules are not fixed

The main statement is: The rules are either lenient or fixed

We check the option according to the logic:

1) DA

D. The rules are not fixed

A. The rules are lenient

Statement D is negative and statement A is positive. The rules are lenient means the rules are not fixed, the rules are soft and gentle. So the two statements are logically consistent.

2) CA

C. The rules are fixed

A. The rules are lenient

Statement C is positive while statement A is positive. So the two statements are logically not consistent.

3) AB

A. The rules are lenient

B. The rules are not lenient

Statement A is positive while statement B is negative. But both statemates talk about the lenient. So the two statements are logically not consistent.

4) BD

B. The rules are not lenient

D. The rules are not fixed

Statement B is negative while statement D is negative. So the two statements are logically not consistent.

Hence, ‘DA’ is the correct answer.
