问题 According to this passage, a diet high in plant-based foods plays an important role in fighting all kinds of diseases. [br] It is proved that the uncontrolled activity of free radicals caused many cancers.

选项 A、Y
B、N
C、NG

答案 B

解析 词语理解题。在本文的第一大部分(Cancer Fighters)的第四段中就提到:“The uncontrolled activity of free radicals is believed to cause many cancers"。这说明:人们认为自由基的无控制活动会导致许多癌症。所以,说" It is proved”是没有依据的。
