问题 Only when ________with water can this liquid be used to clean wounds.

选项 A、purified
B、devised
C、diluted
D、vaporized

答案 C

解析 动词辨义。dilute意为“稀释”,如:dilute alcohol with water(在酒精中加水稀释);purify意为“净化,提纯;使完美”;devise意为“想出,计划”,如:devise how to do that(想想该怎样做);vaporize意为“使气化”。根据题意,在液体中加水不可能是提纯或气化,而应是稀释,故C)为正确选项。
