render指使得的意思，使得之前的misgiving疑虑全都没有用了。所以选Moot

但我觉得这个就是典型的中西方思维的区别啊，按中式思维选C绝对没问题。

关UID：3532436

大意是 Journal published finding showed those misgiving were moot.
期刊发表了她的实验 表明 之前关于她实验控制组有效性的疑虑 是不重要的
moot在这边的意思是trivial 不重要的

That的这种写法其实蛮常见的, 就比如:
That his money was pilfered by his classmate two years ago made him hard to believe people.
这里that和made之间的内容全部都是主语, 意思就是“his classmate pilfered his money”这件事使得他很难相信别人.

这句话也是一样.
