OG12 - 114求助

龍之哀伤

定位: The recently developed theory has considerable practical importance. Most of the gold deposits discovered during the original gold rushes were exposed at the Earth’s surface and were found because they had shed trails of alluvial gold that were easily traced by simple prospecting methods. Although these same methods still lead to an occasional discovery, most deposits not yet discovered have gone undetected because they are buried and have no surface expression.

题目:
114. According to the passage, methods of exploring for gold that are widely used today are based on which of the following facts?
(A) Most of the Earth’s remaining gold deposits are still molten.
(B) Most of the Earth’s remaining gold deposits are exposed at the surface.
(C) Most of the Earth’s remaining gold deposits are buried and have no surface expression.
(D) Only one type of gold deposit warrants exploration, since the other types of gold deposits are found in regions difficult to reach.
(E) Only one type of gold deposit warrants exploration, since the other types of gold deposits are unlikely to yield concentrated quantities of gold.


别的选项都无视, 我选的 B 正确答案是C, 完全相反, 请各位指点下....我觉得很明显是B啊....

The challenge in exploration is therefore to unravel the subsurface geology of an area and pinpoint the position of buried minerals. 【Methods widely used today】 include analysis of aerial images

今天读到这篇，也在这里栽了跟头。搜了解释发现还是不明白。看了dayuyunhai兄的提醒“吃透一篇”，又重新读了一遍，忽然觉得豁然开朗：

题目问的是methods of exploring for gold that are widely used “today ”，回到原文。看我下面截取的文章片段，然后看我用引号引起来的3个点，就会发现答案应该是C。

Most of the gold deposits discovered during the “original ”gold rushes were
exposed at the Earth's surface and were found
because they had shed trails of alluvial gold
(15) that were easily traced by simple prospecting
methods. “Although these same methods still lead
to an occasional discovery, most deposits not yet
discovered have gone undetected because they are
buried and have no surface expression”.
(20)    The challenge in exploration is therefore to
unravel the subsurface geology of an area and
pinpoint the position of buried minerals. Methods
widely used ”today “include

这个定位第二段最后一句就好啦…
能请问各位大牛纠结什么么？？还是我想的太简单所以蒙对了？
