Hi,

First off: this is a strengthen question so you have to find an answer to reinforce the conclusion of the argument.

Moreover, this an EXCEPT question, which means you have to find the right answer among those that weaken the argument or are neutral. I.E the contrary of strengthen.

Now, malaria or dengue are two serious illness that in a person with an immune system not on average or weak can have serious consequences. As such, your goal is to find something that is NOT related to this scenarion

(A) Medicines taken to prevent or treat malaria can cause serious health complications for people with weak immune systems.

You are infected. so you need a cure. And the medicines could have serious collateral damage. Good

(B) The Nicaraguan government is trying to reduce the number of mosquitoes on the Mosquito Coast.

This question nothing helps about the spread of the infection or something explanation immune system - related. No Good. The right one.

(C) A compromised immune system has difficulty fighting either viral or parasitic infections.

The immune system is under stress if attacked. Good

(D) During the rainy season, the populations of both Aedes and Anopheles mosquitoes multiply in the Mosquito Coast.

This scenario could exacerbate the spread of the infection. Good

(E) The most effective chemical insect repellent has been shown to cause brain damage upon repeated application to the skin.

This scenario could be even worse when you try to protect yourself from mosquitos.

Ask for further assistance.
