Our _____ sensitivity decreases with age. By age 60, most people have lost 40 percent of their ability to smell and 50 percent of their taste buds.
【正确答案】
D
【答案解析】解析：考查形容词辨析。由题目中的复现词ability to smell和taste buds可知答案为sensory“感觉的，传递感觉的”，sensory sensitivity即“感官能力”。sensible意为“明智的，合情理的”；senseless意为“失去知觉的，不省人事的”；sensitive意为“敏感的”。
