Question

Choose the option that best corrects the underlined words:
The child felt that doing mathematical problems was more interesting than scientific experiments.

• A. NO CHANGE
• B. performing scientific experiments
• C. that of scientific experiments
• D. science

Answer 1

The correct option is B performing scientific experiments

The underlined phrase isn't parallel to the form of the phrase 'doing mathematical problems'. It requires to be corrected. Hence option A is incorrect. Option B is correct because it contains the correct grammatical structure Gerund + Adjective + Noun. Option C is incorrect because it contains a demonstrative instead of a gerund. Option D is incorrect because it does not include the required gerund as well as noun.
