The new medication was designed to _______ the symptoms of seasonal allergies without causing the drowsiness associated with older treatments. Clinical trials showed promising results.
Which choice completes the text with the most logical and precise word or phrase?
worsen
diagnose
relieve
spread
Correct Answer: C
Choice C is the best answer. The passage describes medication meant to address symptoms without side effects, with "promising results." "Relieve" means to ease or reduce, fitting this therapeutic purpose.
Choice A is incorrect because "worsen" contradicts promising medical results. Choice B is incorrect because "diagnose" means to identify, not treat symptoms. Choice D is incorrect because "spread" contradicts the goal of reducing symptoms.
