有趣的长难句17

昨天的正确答案是D，小伙伴们觉得难吗？今天的题目有点难哦，我觉得改写得有些奇葩，导致难度增加。如果有小伙伴觉得今天的改写不错，可以分享给我。

今天的题目选自《William Smith》一文，威廉·史密斯是英国地质学家，生物地层学的奠基人，英国人称他为“地层学之父”。通常传记体文章难度不大，高难度词汇也不多，因此，怎样编出一道高于平均难度的题目是需要老师们绞尽脑汁思考的，于是，就有了这样一组改写。

But as more and more accumulations of strata were cataloged in more and more places, it became clear that the sequences of rocks sometimes differed from region to region and that no rock type was ever going to become a reliable time marker throughout the world.

答题之前先理清原题中表达了几层意思，从中找出勾稽关系，再推导正确答案。

Which of the sentences below best expresses the essential information in the highlighted sentence in the passage?

A. The discovery of regional differences in the sequences of rocks led geologists to believe that rock types could someday become reliable time markers.

B. Careful analysis of strata revealed that rocks cannot establish geological time because the pattern of rock layers varies from place to place.

C. Smith's catalogs of rock strata indicated that the sequences of rocks are different from place to place and from region to region.

D. Because people did not catalog regional differences in sequences of rocks, it was believed that rocks could never be reliable time markers.
