Q17 - A large amount of rainfall

[ManhattanPrepLSAT1]

This argument is totally absurd. Just because humans cannot control one factor contributing to the occurrence of encephalitis does not mean that we cannot control other factors contributing to the occurrence of encephalitis. For example, we may not be able to control the weather, but we can control mosquitoes with pesticides and proper drainage. So the correct answer is (C) because the argument ignores other possible ways humans could affect the occurrence of encephalitis.

(A) is a flaw that could be used to describe another flawed argument but is not occurring here. The stimulus does not confuse a correlation between two events with a cause and effect relationship as is stated in this answer choice.
(B) is way off track. The argument never claims one outcome to be desirable.
(C) is the correct answer choice. It brings to attention that there may be other ways of controlling the occurrence of encephalitis.
(D) is a funny answer choice. It says that since a large amount of rainfall in April and May aggravates the occurrence of encephalitis that without that rain encephalitis would not exist.
(E) is not a flaw because it’s perfectly fine to draw a conclusion about what is possible for a claim about what is actually the case.

I don't get why D is a funny a/c. I was between D and C and chose the former, thinking that the author had an assumption that Rain/weather was the ONLY means of an increased threat of encephalitis.


And by D, no rain would lead to no increased threat.

I obviously get that theres more than one way to decrease the threat, but what's the difference between C and D in this respect?
