单选题 The families of other ALD patients thought that ________.

A、 the research for the new cure would cost too much money
B、 the efforts of Lorenzo's parents were a waste of time
C、 Lorenzo's parents would succeed in finding a cure
D、 Lorenzo's oil was a real cure for ALD

【正确答案】 B

【答案解析】事实细节题。文章第二段末句说They thought the efforts to find a cure were a waste of time…(他们认为寻找治疗ALD的方法只是在浪费时间…)因此选B)。 [避错指导] A)“新方法的研制将耗资巨大”，文章没有提及；C)“洛伦佐的父母最终会找到治疗的方法”，并非其他ALD患者家属的看法；因为当时Lorenzo's oil 还未被发现，所以说它“是一种真正能治疗ALD的药物”还为时过早，故排除D)。
