Okay let's diagram:

"if global warming continues or if the use of pesticides is not expanded, then ecologists predict that the incidence of malaria will increase."

P1: GWC or UPE ==> IMI
not IMI ==> not GWC & not UPE

"the use of pesticides is known to contribute to global warming."

Don't be fooled and take this as a Sufficient & Necessary statement. The use of pesticides does not cause global warming, it merely contributes to it. It may or may not be sufficient.

"so it is inevitable that we will see an increase in malaria in the years to come."

C: IMI

So we are asked to choose the answer that has the most similar reasoning as the argument above. The argument reasons that since the use of pesticides contributes to global warming, then because our principle rule states that if global warming continues or if the use of pesticides is not expanded, then the incidence of malaria will increase.

Hope that helps you choose the correct answer! Please let us know if you have any other questions.

When it says "if the use of pesticides is NOT expanded" shouldn't it be written as GWC or not UPE?
