Question

The sentence has four underlined words or phrases. Choose the word or phrase that must be changed for the sentence to be correct.

It can take hundreds of different experiments to achieve a ultimate solution.

• A. It
• B. hundreds
• C. achieve
• D. a

Answer 1

Answer: (D)

a

The sentence begins with 'it' indicating the noun being a thing. So, option A) is incorrect as 'its' is correctly used in the sentence. The next underlined word is 'hundreds' which goes with 'different experiments' that follow it as both indicate plural quantity. Therefore, option B) hundreds is incorrect. 'Achieve' is correctly used as a verb in the given sentence and so option C) achieve is incorrect. 'Ultimate' begins with a vowel and so the article to be used before it is 'an' and not 'a'. Therefore, the correct option is option D) a which needs to be changed to 'an' for the sentence to be correct.
