Health professionals often use Body Mass Index (BMI) as a primary indicator of a person's fitness; however, critics argue that BMI is an _______ measure because it does not distinguish between muscle weight and fat weight.
Which choice completes the text with the most logical and precise word or phrase?
imperfect
exhaustive
ideal
irrelevant
Correct Answer: A
Choice A is the best answer. The text states that BMI "does not distinguish" between muscle and fat. Therefore, it is flawed. "Imperfect" means faulty or incomplete.
Choice B is incorrect because "exhaustive" means complete. Choice C is incorrect because "ideal" means perfect. Choice D is incorrect because "irrelevant" means having no connection, but it is still a "primary indicator."
