In which of the following instances would you be most likely to write a compare-and-contrast essay? A. when writing a report on how to reduce air pollution B. when writing a mystery story set in an abandoned hotel C. when writing about why Great Britain was the birthplace of the Industrial Revolution D. when writing about the effects of high-fat and low-fat diets

I would say the effects of high-fat and low-fat diets.

Explanation:

For [A] a report on how to reduce air pollution would be expository or persuasive.

For [B] a mystery story would be entertaining and engaging.

For [C] why Great Britain was the birthplace of the industrial revolution would be a persuasive exposition, factually based.

For [D] you would write and exposition comparison to describe the benefits and detriments of the two types of diets, thus a "compare-and-contrast" essay.

Cheers.
