问题 According to this passage, a diet high in plant-based foods plays an important role in fighting all kinds of diseases.
Investigators don’t ______ how many phytochemicals exist and how they work.

选项

答案know much about

解析在本文的第一大部分(Cancer Fighters)的第八段中就提到：Investigators have only an inkling of how many phytochemicals exist and how they work。句中的“have only an inkling of”即指"don’t know much"。
