求助，一道GWD阅读题

油闹家

没错，原文如下：
“environmental factors-including changes in the tide's hydrostatic pressure, salinity, mechanical agitation, and temperature-can alter the period of its biological clock according to changes in the tidal cycle. ”
因此，“A. The accuracy of the commuter diatom’s biological clock varies according to changes in the tidal cycle”是错误的，把“The accuracy of the commuter diatom’s biological clock ”改成“]the period of its biological clock ”就正确了。
因为varies according to changes in the tidle cycle (随着潮汐循环而改变的)不是“ accuracy ”，而是“ the period of its biological clock ”
不知道这样的解释你听明白了没有？

油闹家

A. The accuracy of the commuter diatom’s biological clock varies according to changes in the tidal cycle.
A句的意思是生物钟的精度会随着潮汐循环的改变而改变。
但是第二段的前几句的意思是“生物钟”随潮汐循环的改变而改变，没有提到“精度”。这属于偷换概念了。

根據第二段：
environmental factors-including changes in the tide's hydrostatic pressure, salinity, mechanical agitation, and temperature-can alter the period of its biological clock according to changes in the tidal cycle

並不是只有tidal cycle會影響 還有很多原因，所以Ａ是錯的
