Multiple choice

Directions: The following items consist of two statements, one labelled as 'Assertion (A)' and the other labelled as 'Reason (R)'. You are to examine these two statements carefully and decide if the Assertion (A) and the Reason (R) are individually true and if so, whether the reason is a correct explanation of the Assertion. Select your answer to these items using the codes given below. Assertion (A) : In a resequent fault line scrap, the down throw side will form lower ground. Reason (R) : The down throw side possesses the softer rocks at the level of present erosion surface.

  1. Both A and R are true and R is the correct explanation of A.

  2. Both A and R are correct but R is not the correct explanation of A.

  3. A is true but R is false.

  4. A is false but R is true.

C Correct answer
Explanation

In a resequent fault, the downthrow side contains softer rocks that erode more easily at the current erosion level, forming lower topography. The Assertion is true. However, the Reason, while factually correct about softer rock presence, does not fully explain the mechanism - it's the differential erosion rate of these softer rocks that creates the lower ground, not merely their presence.
