Question

From among the given alternatives, identify the conclusion of the following argument

If A is B, then C is not D.
If C is not D, then E is not F.
If E is not F, then G is not H.
Therefore

Options

• If G is not H, then A is B

• If A is B, then G is not H

• If G is H, then A is B

• If A is not B, then G is H

Answer 1

If A is B, then G is not H

Explanation:

'If A is B' is the main cause of the subsequent outcomes. So if 'If A is B' takes place all the outcomes will automatically take place. (A) can be misleading.  But (A) says because the effect is there the given cause is also there. The effect can take place even for some other causes (note the difference between necessary and sufficient cause) also.
