Question

Find the synonym of the underline word.
The serum was supposed to make the patient immune from further infection.
a)Contagious
b)Not susceptible
c)Open
d)Sick
e)Subject to

Answer 1

Hint: Synonyms are words that mean the same. If you are immune to a disease, it means you are resistant to it. You must have been injected with some medicine that has produced antibodies in your body that fights against that disease. In a general sense, if something does not affect someone, he is immune to that something.

Complete answer:
 According to the given sentence, a serum was supposed to make the patient immune to infection. The patient is not supposed to suffer from the disease again- he has become resistant to it. Thus, the correct option is b, that is, not susceptible. Susceptible means being easily harmed. Not susceptible means not being easily harmed. Thus, an immune person is not susceptible to diseases.
Option a is contagious. A contagious disease spreads easily from one person to another, especially through direct contact. The Covid-19 is a contagious disease.
Option c is open. In the given sentence, open would mean that the person is likely to get the disease which is not what the sentence is trying to convey.
Option d is sick. To be sick does not mean being immune. If you are immune, you don’t fall sick. If you are not immune, you fall sick. They are two different words and not synonyms of each other.
Option e is ‘subject to’. ‘Subject to’ means to be ‘exposed to’. Being immune does not subject you to diseases so it is clearly a wrong answer.

Note: Remember that the word immune is used in a positive sense. Sometimes people think that immune means to be prone to diseases when it is actually the opposite. When you are immune, you are safe from diseases.
