Selecting Words

Directions:

In the following passage at certain points you are given a choice of three words marked (a), (b) and (c), one of which fits the meaning of the passage. Choose the best word out of the three. Mark the letter, viz., (a), (b) or (c), relating to this word on your Answer Sheet. Examples K and L have been solved for you.

K L

The (a) boy was in the school in Simla, (a) She was home sick.

(a) horse (b) It

(b) dog (c) He

Explanation : Out of the list given in item K, only ‘boy’ is the correct answer because usually, a boy, and not a horse or a dog, attends school. So ‘(a)’ is to be marked on the Answer Sheet for item K. A boy is usually referred to as ‘he’, so for item L, ‘(c)’ is the correct answer. Notice that to solve the first item K you have to read the rest of the sentence and then see what fits best.
