OG12 - 114求助
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.
