Time: 1Hour Full Mark: 70

Objective Questions (50 Marks)

1. Read the following passage and answer the questions based on it : [26 Marks]

One of the most widely spread of bad habits is the use of tobacco. Tobacco is

now smoked or chewed by men, women and even by children almost all over the world.

It was brought to Europe from America by Sir Walter Raleigh four centuries ago and

by now has spread everywhere. I very much doubt whether there is any good in the

habit even when tobacco is not used in excess and it is extremely difficult to get rid of

the habit once it has been formed.

Alcohol is taken in almost all cool and cold climates and to a very less extent in

hot ones. Thus it is taken by those people who live in the mountains, but not nearly

so much by those who live in the plains of India. Alcohol is not necessary in any way

to anybody. Millions of people are beginning to do without it entirely. In India it is not

required by the people at all and should be avoided by them altogether. The regular

use of alcohol even in small quantities tends to cause harm in many ways to various

organs of the body. It affects the liver, it weakens the mental powers and lessens the

general energy of the body.
