The author is primarily concerned with______ [br] The passage implies that which of the following steps would be the first performed by explorers who wish to maximize their chances of discovering gold?
选项
A、Surveying several sites known to have been formed more than two billion years ago
B、Limiting exploration to sites known to have been formed from metamorphic fluid.
C、Using an appropriate conceptual model to select a site for further exploration
D、Using geophysical methods to analyze rocks over a broad area
E、Limiting exploration to sites where alluvial gold has previously been found
答案
C
解析
The best answer is C. According to the author, “to maximize the chances of discovery the explore must …pay particular attention to selecting the ground formations most likely to be mineralized (lines 27-30); the explorer begins by using conceptual models “to identify those geological features that are critical to the formation of the mineralization being modeled, and then tries to select areas for exploration” (lines 35-38). According to the author, geophysical methods are of no value if they are applied to sites that have never mineralized (lines 25-27), so choice D is not correct, and there is no indication in the passage that age of formation would narrow the explorer’ choices, so choice A is not correct . Choice B is not correct because the new theory, which is said to have “considerable practical importance” (lines 8-9) for the discovery of gold, is contrary to the view that gold deposits were deposited from metamorphic fluids. And the passage says that simple prospecting methods that trace alluvial gold only occasionally lead to new discoveries, so choice E is incorrect.
