问题 The most crucial problem any economic system faces is how to use its scarce resources.

选项 A、puzzling
B、difficult
C、terrifying
D、urgent

答案D

解析本句意思是“每个经济体系面临的最重要的问题是如何使用稀缺资源。” crucial“至关紧要的”和urgent“紧急的”含义最接近。puzzling“(使)迷惑的”，例如，I have been puzzling about this question for weeks now．我对这个问题已冥思苦想了好几个星期。difficult“困难的”，terrifying“使感到恐怖的”，例如，The tidal wave formed a terrifying wall of water．海啸形成一堵骇人的水墙。
