A certain tropical island received food donations in the for [#permalink]

Question Stats:
55% (02:28) correct
44% (00:20) wrong based on 1 sessions
Which of the following most logically completes the passage? A certain tropical island received food donations in the form of powdered milk for distribution to its poorest residents, who were thought to be malnourished. Subsequently, the rate of liver cancers among those islanders increased sharply. The donated milk was probably to blame: recent laboratory research on rats has shown that rats briefly exposed to the substances aflatoxin tend to develop liver cancer when fed casein, a milk protein. This result is relevant because _______. A. in the tropics, peanuts, a staple of these island residents, support a mold growth that produces aflatoxin B. the liver is more sensitive to carcinogens, of which aflatoxin may be one, than most other bodily organs C. casein is not the only protein contained in milk D. powdered milk is the most appropriate form in which to send milk to a tropical destination E. the people who were given the donated milk had been screened for their ability to digest milk This one made me think twice... Edit: by carcass

Ans is A; it is the only statement that logically supports the causality in the hypothesis.

Doesn't A say that milk wasn't the cause??? from A we do not know that the aflatoxins in peanuts have anything to do with the liver cancers. all A tells us is aflatoxin from the peanuts is already present in the diets of these residents. the rat relationship is to say that the aflatoxin in milk protein causes cancer. kinda inverted logic.
x = aflatoxins in milk protein
y = aflatoxins in peanuts
not y then x

I pick A.
The way I read it, the stem says that the rats developed liver cancer when fed casein, which is a milk protein. However, the stem argues that this happened because the rats were already exposed to aflatoxin.
Thus the argument is that for rats who are exposed to aflatoxin and then fed casein, liver cancer develops.
Similary, if the humans in the tropics are already exposed to aflatoxin, and then consume the powdered milk which contains casein, liver cancer develops as well

OA=A
The argument asks how the experiment related to what cause the cancer in the island. In an ordinary CR question, I would try to find the relationship between the experiment and the milk. However, this isn't the case. Since milk cause cancer on the island, the experiment is relevant because it might be that Peanuts is the cause of the cancer on the island.

Great explanation BKK, i would like to add just what's stated in the passage, that after the donation of the milk, the islanders sow a sharp increase in liver cancer. Becasue of that they explaioned the experiment with milk, and because the nuts have the same ingredient as milk, it made the cases of liver cancer rise.

Hi Sachin, Let me see if I can help. Simply the passage is saying: Milk was imported to the island
People on the island got liver cancer.
This is blamed on the imported milk.
Because research has shown that if people have milk protein and aflatoxin.SO We know they have milk, we know they have cancer, we need an answer that also tells us they have aflatoxin. Answer A does that. E tells us nothing about the existence of aflatoxin without which, the conclusion is not valid Hope that helps. James

James Hi James, I believe we are trying to weaken the claim that aflatoxin caused cancer. how does A weaken?

Hi Sachin, that's not as I see it. We are asked to logically conclude the passageThe passage's conclusion is that the introduction of milk caused the increase in cancer. We need to find out the reason why they think this. The combination of the info in the question and the info given in A does that: Question: aflatoxin + milk protein causes cancer. Milk (and hence milk protein) was given to the islanders.All we are missing is the presence of aflatoxin... Option A: Islanders have aflatoxin through eating peanuts
