Red blood cells in which the malarial-fever parasite resides are eliminated from a person’s body after 120 days. Because the parasite cannot travel to a new generation of red blood cells, any fever that develops in a person more than 120 days after that person has moved to a malaria-free region is not due to the malarial parasite.
Which of the following, if true, most seriously weakens the conclusion above?

(A) The fever caused by the malarial parasite may resemble the fever caused by flu viruses.
(B) The anopheles mosquito, which is the principal insect carrier of the malarial parasite, has been eradicated in many parts of the world.
(C) Many malarial symptoms other than the fever, which can be suppressed with antimalarial medication, can reappear within 120 days after the medication is discontinued.
(D) In some cases, the parasite that causes malarial fever travels to cells of the spleen, which are less frequently eliminated from a person’s body than are red blood cells.
(E) In any region infested with malaria-carrying mosquitoes, there are individuals who appear to be immune to malaria.

(A) The fever caused by the malarial parasite may resemble the fever caused by flu viruses.
This is not related to the argument
(B) The anopheles mosquito, which is the principal insect carrier of the malarial parasite, has been eradicated in many parts of the world.
This is just extra information.
(C) Many malarial symptoms other than the fever, which can be suppressed with antimalarial medication, can reappear within 120 days after the medication is discontinued.
This supports the theory that parasite remains for 120 days
(D) In some cases, the parasite that causes malarial fever travels to cells of the spleen, which are less frequently eliminated from a person’s body than are red blood cells.
This weakens the conclusion that parasite will die in at max 120 days.
What if it goes into cells of the spleen?.

(E) In any region infested with malaria-carrying mosquitoes, there are individuals who appear to be immune to malaria.
Again just extra information

phoenix08,
Option A can also weeken the conclusion. If 'The fever caused by the malarial parasite may resemble the fever caused by flu viruses' then it is possible that the fever may last for more than 120 days.

Any takers?

Premise: Red blood cells in which malarial parasite resides are eliminated from a person after 120 days
Premise: Parasite can't travel to a new generation of red blood cells
[Assumption: Malarial parasite is completely eliminated from a person after 120 days]
Conclusion: Any fever that develops in persons more than 120 days after that person moved to a malaria-free region is not due to malarial parasite.
We can weaken this conclusion by showing that the fever that develops more than 120 days is indeed caused by malarial parasite although that person is moved to malarial-free region.
A. Out of scope by comparing malarial parasite and flu viruses.
B. Out of scope. The mosquito has nothing to do with the fever here.
C. This is a Shell Game. It does not weaken the conclusion because it mentions about the malarial symptoms that can can reappear within 120 days after the medication is discontinued.
D. Option D breaks the assumption by proving that malarial parasite is not eliminated because it travels to cells of spleen, which are less frequently eliminated from a person’s body than are red blood cells; therefore, malarial parasite can cause fever after a person is moved to a malarial-free region.
E. Out of scope.

What we know of flu viruses from the argument? Nothing, The argument does not deal with Flu Viruses.

Option A would in a way strengthen the conclusion....that it may be flu and not malaria...in case the person suffers from Fever

D it is :), although I did initially confuse with (C). However (C) does seem to trick us into taking an assumption which is not a part of the argument

I chose D

Conclusion: After 120 days if malaria reappear then its not due to malaria parasites.

Only option D says that Still the parasite causes the malaria which is not eradicated with medication because it sits safely in spleen.
