In the following question, 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. By detecting and eliminating diseases at an early stage, (P) / we can prevent an irreversible damages to children (Q) / and contribute to national development (R) / No error (S)?

Option 2 : Q

The error lies in part Q of the sentence. Thus, the correct answer is option 2.

Here, the article an should be eliminated because the word damages is in plural form. A/An are indefinite articles used to refer to a general group of things – a boy, an apple. These articles are always used before a singular noun (and never used before a plural noun – a boys, an apples are incorrect).

Correct sentence -   By detecting and eliminating diseases at an early stage, we can prevent irreversible damages to children and contribute to national development.
