单选题 What distinguished Dr. Jeol Hiderbrand from others as early as in high school?

A、 He was given the key to the chemistry lab.
B、 His discovery of the correct formula for some chemical compound.
C、 He learned more chemistry from his teacher.
D、 His excellent score in chemistry learning.

【正确答案】 B

【答案解析】[解析] 本题考查事实细节。是什么使Dr．Jeol Hiderbrand早在高中阶段就与众不同呢?他在中学时就发现了某种化合物的正确的分子式，这使他与众不同。[C]无从谈起；[D]原文未提及，显然应排除。剩下的[A]和[B]需仔细斟酌。[A]几乎就是照抄原文，但有一字之差(key而非keys)，故不合题意。
