98. An experiment was done in which human subjects recognize a pattern within a matrix of abstract designs and then select another design that completes that pattern. The results of the experiment were surprising. The lowest expenditure of energy in neurons in the brain was found in those subjects who performed most successfully in the experiments.

Which of the following hypotheses best accounts for the findings of the experiment?

(A)
The neurons of the brain react less when a subject is trying to recognize patterns than when the subject is doing other kinds of reasoning.

(B)
Those who performed best in the experiment experienced more satisfaction when working with abstract patterns than did those who performed less well.

(C)
People who are better at abstract pattern recognition have more energy-efficient neural connections.

(D)
The energy expenditure of the subjects' brains increases when a design that completes the initially recognized pattern is determined.

(E)
The task of completing a given design is more capably performed by athletes, whose energy expenditure is lower when they are at rest.

不太明白D选项给出的解释：

The most successful subjects would presumably not have completed fewer patterns than average,so the posited increase in energy would likely lead to higher energy expenditures for them ,not lower.

求教解释与选项的关系，谢谢指教

就是想问问是怎么驳斥该选项的

(D) The energy expenditure of the subjects' brains increases when a design that completes the initially recognized pattern is determined.

The most successful subjects would presumably not have completed fewer patterns than average,so the posited increase in energy would likely lead to higher energy expenditures for them ,not lower.

首先D说，当完成initially recognized pattern 的Design被判定的时候，消耗的能量会增加。 D的解释说，那些表现最好的人，他们完成的PATTERN数量不会比平均数低，所以按照D的理论，因为每次判定的时候能量消耗都会增加，表现最好的那些消耗的能量肯定高，而不是原文所说的表现最好的消耗的能量反而低。与原文意思矛盾。
说的不对的多指教哈！

谢谢你的指导，同意。

最能说明原因的是要表达低能量消耗与实验中人的performance的关系即可的出C
