Q5 of 805 Page 1

Fill in any four of the blanks in the paragraph given below with the help of options that follow :

The modern student (a) the importance (b) physical exercise. He spends one to two hours in open air (c) he takes part in different sports. However, care should (d) not to overstrain (e) body.


(a) (i) understood (ii) understand


(iii) have understand (iv) understands


(b) (i) of (ii) by (iii) from (iv) with


(c) (i) how (ii) which (iii) where (iv) why


(d) (i) be taken (ii) took (iii) takes (iv) has taken


(e) (i) a (ii) an (iii) the (iv) some

a) As we refer to a generic idea and the subject is also general, the present plural form of the verb ‘understand’ will be used. Hence, the correct option is (ii).


b) We understand the importance of something, so ‘of’ will be used. Hence, the correct option is (i).


c) In the context given, we refer to a place and define the action he does. So ‘where’ will be used. Hence, the correct option is (iii).


d) ‘Should’ always takes the passive verb and so ‘be taken’ will be used. Hence, the correct answer is (i).


e) Some missing information in the question.
