Hi. Just having trouble distinguishing answer C from D in this question. I think D is wrong only because it is plural. Can someone please confirm? I think it's saying the same thing as the right answer (C) in a different way. Please explain if I am wrong.
D. Takes for granted that threat (increased encephalitis) that is aggravated by certain factors (rain) could not occur in the absence of those factors (rain.)
Takes for granted that increased encephalitis that is aggravated by rain could not occur without rain. IC can only occur with rain. No other factors.
C. Ignores the possibility that a certain type of outcome (increased encephalitis) is dependent on more than one factor (rain).
Ignores the possibility that other factors (that aren't rain) could contribute to IC. D says increased encephalitis could not occur without rain. No other factors seems to be established in both answer choices.
I don't really see much of a difference in the meaning here. Please tell me if I'm interpreting this incorrectly.
