In malaria-infested areas, many children tend to suffer several bouts of malaria before becoming immune to the disease. Clearly, what must be happening is that those childrenтАЩs immune systems are only weakly stimulated by a any single exposure to the malarial parasite and need to be challenged several times to produce an effective immune response.

Which of the following, if true, most seriously undermines the explanatory hypothesis?

a.Immediately after a child has suffered a bout of malaria, the childтАЩs caregivers tend to go to great lengths in taking precautions to prevent another infection, but this level of attention is not sustained.
b.Malaria is spread from person to person by mosquitoes, and mosquitoes have become increasingly resistant to the pesticides used to control them.
c.A certain gene, if inherited by children from only one of their parents, can render those children largely immune to infection with malaria.
d.Antimalaria vaccines, of which several are in development, are all designed to work by stimulating the bodyтАЩs immune system.
e. There are several distinct strains of malaria, and the bodyтАЩs immune response to any one of them does not protect it against the others.

Can someone explain what is wrong with "C".

Here was my logic:

If [A certain gene, if inherited by children from only one of their parents, can render those children largely immune to infection with malaria] were true wouldnt it weaken the conclusion that <children’s immune systems are only weakly stimulated by a any single exposure to the malarial parasite and need to be challenged several times to produce an effective immune response>


I follow the template if <AC "C" were true> wouldnt it weaken the conclusion <conclusion>.......

Anyone? Anyone? Bueller...?

Can someone shed some light on what is wrong with my "thought process"?

Gmataquaguy, ‘C’ is out of scope because we are talking about children who tend to suffer several bouts of malaria before becoming immune. According to ‘C’ - those children are immune to the diesease because of their inherited gene.

Well let's see

A. So it says that children get malaria often and so may actually strengthen the argument so i'm deleting this one
B. If mosquitoes are becoming resistant then how are children becoming more inmune? This actually doesn't tell us much
C. Genes are what make children inmune, could be an alternate reason, Im keeping this one
D. This is out of scope. I don't care how Antimalaria vaccines work
E. Well, if malaria diseases are different then it cannot be that the continued exposure are making them inmune to them no? So I think that this is the best answer cause it directly attacks the argument

IMHO answer is E

Let us know the OA please

Cheers!

PRETHINKING........IT IS NOT THAT AFTER SEVERAL BOUTS OF SIMILAR MALARIA, DOES ONE BECOME IMMUNE..... INFACT ONE COULS BECOME IMMUNE TO A SINGLE BOUT ALSO... BUT THE IMMUNITY DEVELOPED IS OF NO USE IN ANOTHER STAIN......


MATCHES "E"... HENCE IMO "E".....

a.Immediately after a child has suffered a bout of malaria, the childтАЩs caregivers tend to go to great lengths in taking precautions to prevent another infection, but this level of attention is not sustained............... IRRELEVANT...............
b.Malaria is spread from person to person by mosquitoes, and mosquitoes have become increasingly resistant to the pesticides used to control them. ......IRRELEVANT.............
c. A certain gene, if inherited by children from only one of their parents, can render those children largely immune to infection with malaria...IRRELEVANT.....
d.Antimalaria vaccines, of which several are in development, are all designed to work by stimulating the bodyтАЩs immune system.....SO WHAT... WE ARE TALKING OF SELF BUILT IMMUNITY.....
e. There are several distinct strains of malaria, and the bodyтАЩs immune response to any one of them does not protect it against the others......CORRECT....
