两个逻辑题目请详细指教

shany

1.同意nobody. 要强烈关注at least ，明显的标志词，有时却可能是陷阱。

2.支持A. 原文有概念跳跃。后两句暗示The finding by serendipity does not directly bear on the funded research。改写后就是A.

shany

2.前提：investigators ignore anything that does not directly bear on the funded research.
结论：serendipity can no longer play a role in scientific discovery。

结论把Serendipity等同于anything that does not directly bear on the funded research,替换了概念.除非有必要条件only non-serendipity can directly bear on the funder research成立.即A.

关于D,你是否认为如果研究者未能获得资助，就不会受赞助商的约束，可以有意外发现？但文中已提到investigators are heavily dependent on large grants to fund their research.所以不仅不会有意外收获，甚至连预期的结果都困难。

欢迎讨论。
