In the following questions, one part of the sentence may have an error. Find out which part of the sentence has an error and click the option corresponding to it. If the sentence is free from error, click the 'No error' option. Indra Gandhi declared an emergency (A) in India at 1975 solely to (B) protect her political position. (C)/ No error (D)?

Option 2 : B

The error is in the second part of the sentence. Therefore, option 2 is the correct answer.

The second part of the sentence is incorrect because the preposition used is wrong. While both the prepositions ‘in’ and ‘at’ are used to indicate the position or place of a thing or to indicate time, ‘in’ is used to indicate larger places and longer periods or unspecified period of time while ‘at’ is used for a particular place and particular time, eg, ‘I will see you in an hour’ and ‘I will see you today at 8 p.m.’. Since 1975 is a year, that means a really long period of time, therefore ‘in’ should be used in the sentence.

Correct sentence:
