题目：
One summer, floods covered low-lying garlic fields situated in a region with a large mosquito population. Since mosquitoes lay their eggs in standing water, flooded fields would normally attract mosquitoes, yet no mosquitoes were found in the fields. Diallyl sulfide, a major component of garlic, is known to repel several species of insects, including mosquitoes, so it is likely that diallyl sulfide from the garlic repelled the mosquitoes.
Which of the following, if true, most strengthens the argument?
Which of the following, if true, most strengthens the argument?
选项:
A、Diallyl sulfide is also found in onions but at concentrations lower than in garlic.
B、The mosquito population of the region as a whole was significantly smaller during the year in which the flooding took place than it had been in previous years.
C、By the end of the summer, most of the garlic plants in the flooded fields had been killed by waterborne fungi.
D、Many insect species not repelled by diallyl sulfide were found in the flooded garlic fields throughout the summer.
E、Mosquitoes are known to be susceptible to toxins in plants other than garlic, such as marigolds.
答案:
D
提问：
请问c为什么不对？
原文：大蒜地with a large mosquito population。水里没蚊子卵，大蒜驱蚊。
按c选项，大部分大蒜被杀了，所以蚊子有large population，属于支持。

提问：
请问胡凡老师，， 这道题逻辑链是通过一个现象no mosquitoes were found in the field且garlic会驱赶包括蚊子在内的昆虫 得出garlic repelled了蚊子吗？ 这道题d选项是无因无果吗？ 无因无果的本质是否可以理解为若没有这个因，则不会产生这个果，排除了其他原因会影响结论吗？
