og11-99中答案解释中的一句话不理解 请达人点解下

题目：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. Th 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 n the experiments.

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

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

Reasoning:In order to account for the findings,the hypothesis must suggest a plausible link between successful performance and the energy expenditure of neurons in the brain.Where is there areasonably direct relationship between the given factors and the conclusion that is drawn?Understand that hypotheses based on factors not included in the experiment cannot be used to account for the findings

最后这一句怎么看都没明白

麻烦大家给我指点下吧 鞠躬~~~~~~~~~~~

继续期待 指点

尝试理解一下：

要明白那些建立在实验中没有包含的因素的假设是不可以用于说明（实验）发现的。

顶alice的翻译

我觉得这句是定从套定从,看起来有点绕

Understand that hypotheses( based on factors ((not included in the experiment)) cannot be used to account for the findings
            

划线部分是understand的宾语,  ((not included in the experiment)) 修饰factors, ( based on factors ((not included in the experiment)) 修饰hypotheses

谢谢楼上两位好心的mm
