Question

Choose the option that best corrects the underlined words:
Chloe wondered if cleaning the house was more strenuous than a gym workout.

• A. that of a gym workout
• B. cleaning a gym workout
• C. working out at the gym
• D. NO CHANGE

Answer 1

The correct option is C working out at the gym

When a comparison is made between two phrases, they should be parallel to each other in their grammatical structure. The underlined phrase "a gym workout" isn't consistent in structure to that of the phrase "cleaning the house" which it is being compared to. It needs to be changed, hence option D is incorrect. Option A is incorrect because 'that' is a demonstrative which modifies a noun that's been mentioned before. In the given sentence, it does not modify any such noun. Option B is grammatically incorrect. Option C is correct because the phrase "working out at the gym" is parallel in structure to that of the phrase "cleaning the house".
