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) : Seas near the equator receive rainfall throughout the year. Reason (R) : High temperature and high humidity, near the equator, cause convectional rain in most afternoons.

  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.

A Correct answer
Explanation

Both statements are true and the Reason correctly explains the Assertion. Seas near the equator do receive rainfall throughout the year because high temperatures cause continuous evaporation, and high humidity provides abundant moisture. When this warm, moist air rises (convection), it cools and condenses, producing afternoon convectional rainfall nearly every day. This is the mechanism behind the observed pattern.
