Which choice completes the text with the most logical and precise word or phrase?

measure
Correct Answer: A
Choice A is the best answer. The passage describes educational efforts that resulted in "increased concern," indicating a goal to raise awareness. "Heighten" means to increase or intensify, fitting this educational objective.
Choice B is incorrect because "suppress" is the opposite of increasing awareness. Choice C is incorrect because "question" doesn't convey increasing awareness. Choice D is incorrect because "measure" assesses but doesn't increase awareness.
