A recent study demonstrated that parents living with children consume nearly five more grams of fat per day, on average, than do adults living without children. The higher fat intake among these parents is probably attributable to their snacking on the pizza and cookies that tend to be plentiful in households with children.

Which of the following, if true, would most seriously weaken this explanation of the parents' higher fat intake?

(A) On average, households with children spend $15 more per week on pizza and cookies than do households without children. (B) Households with children purchase much more whole milk, which has a high fat content, than do households without children. (C) Children consume most of the pizza and cookies in any given household. (D) Parents ought to set a good example for their children, in dietary choices as in other matters. (E) Not all parents living with children consume more grams of fat than do adults living without children.

B gives another cause for higher fat intake by families in which parents live with children. Therefore IMO B

B and C are the strong candidates.

B says that households are spending on "whole milk" - Ok so this is another reason for high fat but does it weaken the statemenent that "pizzas" are culprit!!
C. Children consume most pizzas - It means that buying habit does not prove that owner will consume also...hence weakens the argument.

IMO C.

This attacks the argument which syas that pizzas and cookies are the main source of fats and hence the reason of more consumption of fats among adults. But B says Whole milk is another source of high fat content. I didnt chose C bcos children may consume most of the pizzas and cookes but the other part is still consumed by adults. Hence they are tsill having more fat contents as compared to the adults without children. nitya34 wrote: A recent study demonstrated that parents living with children consume nearly five more grams of fat per day, on average, than do adults living without children.

Agree with you C, but not B

B strengthens rather than weakens.

Argument: eating FAT food (pizza and cookie)---> high fat intake

One way to weaken is: NOT eating FAT food ---> STILL high fat intake. So only C nearly implies the meaning above. Furthermore, in order C is the best candidate that weakens strongly the argument, "most" in C should be "all".

Say something about B: you cannot imply that "purchase much more whole milk" means "snacking much more whole milk". PURCHASE and SNACK are different.

1. if you assume: PURCHASE is the same as SNACK, B strenthens argument.
2. if you assume: PURCHASE is different from SNACK, B is outside of scope.

That is why C is not a good choice in my opinion. It is possible to say: children in house - a bit of pizza for adults, no children in house - no pizza for adults.

I can find B is the close answer since to weaken the explaination
"The higher fat intake among these parents is probably attributable to their snacking on the pizza and cookies that tend to be plentiful in households with children." we have to find the alternative to this which is nothing but option B "Households with children purchase much more whole milk, which has a high fat content, than do households without children." So definitely pizza and cookies are not the reason for high fat rather it is for Milk.

If you look the option C --- the world MOST is not quantifiable. Here most means Parents with children still consume some part of Pizza and cookies. That small portion may be enough to cause excess fat.

yes i also with B. conclusion is cookies and pizza are the cause for the high fat, but B indicates that its not cookies and pizza but the whole milk with high fat is the cause, cause other than presented in conclusion.

A recent study demonstrated that parents living with children consume nearly five more grams of fat per day, on average, than do adults living without children. The higher fat intake among these parents is probably attributable to their snacking on the pizza and cookies that tend to be plentiful in households with children.

Which of the following, if true, would most seriously weaken this explanation of the parents' higher fat intake?

Explanation:
----------------------
A) On average, households with children spend $15 more per week on pizza and cookies than do households without children. ---> Not relevant. If anything, it will strengthen the explanation. B) Households with children purchase much more whole milk, which has a high fat content, than do households without children. ---> This gives another reason that may be behind the parents’ (living with children) higher intake of fat. C) Children consume most of the pizza and cookies in any given household. ---> I guess everyone with the following: 1. Author has no doubt that parents living with children have a higher intake of fat than those adults who stay without children. 2. Author is trying to provide reason for the above observation by attributing their (parents) higher intake of fat to pizzas & cookies (yum-yum). Option C mentions the word most, which I think is equivalent to almost all. Now if the children consume almost everything then parents will be left with almost nothing. If it is so, then it will actually mean that parents (staying with children) don’t have comparably higher intake of fat than those adults who live without children. This will actually violate point 1, thus going against the author’s view that parents staying with children have a higher intake of fat. If point 1 is violated in the first place then how are we going to focus on point 2, which is the main point of discussion? The whole point focuses on the reason for higher intake of fat & NOT whether parents with children have a higher intake than those adults who stay without children. So, discard this option. D) Parents ought to set a good example for their children, in dietary choices as in other matters. ---> Yes, they ought to but do they? And even if they do so, it goes against the author’s view that parents staying with children have a higher intake of fat than those who are staying without children. E) Not all parents living with children consume more grams of fat than do adults living without children. ---> Inconclusive. ---------------------- I go with option B. Hope that helps.

Conclusion: parents living with children consume nearly five more grams of fat per day, on average, than do adults living without children
Evidence: the higher fat intake among these parents is probably attributable to their snacking on the pizza and cookies that tend to be plentiful in households with children.
Assumption: the assumption that the more pizza and cookies is available the more parents eat
So the option C breaks the assumption, therefore it weakens the conclusion.

Thanks "fiesta",

Anyway, just give some more words for "Technext":

. Stop here and you should realize that ANOTHER THING rather than SNACKING pizza of the children available CAUSES the high fat intake. You have ALREADY weaken the argument.

But if your reasoning continues like:

Technext wrote:

You are strenthening the argument. Since you agrees that eating high fat foods causes high fat intake.

Definitely (B), definitely not (C).

Notice that the conclusion we are trying to weaken is a cause-and-effect claim: Snacking on pizza and cookies is the CAUSE of the higher fat intake among parents with children (compared to adults without children). The question makes it clear that we must attack the cause-and-effect relationship when it tells us to weaken NOT the statement that these parents consume more fat, but the EXPLANATION for this fact.

By far the most common way to weaken a cause-and-effect conclusion is to provide information that makes a different cause possible or likely. We don't have to PROVE that the different cause is correct; we just have to show that it is possible. In this case, we are looking for a different possible reason why the parents with children could consume more fat than adults without children.

(B) clearly provides a different possible reason: There is more whole milk in the house, and whole milk has more fat than other milk. We do not have to assume or prove that the parents actually drink that milk; we weaken the argument as soon as we show that there is another possible source (other than pizza and cookies) for their higher fat intake.

(C) does not affect the argument one way or the other. "Most" does not mean "almost all"; it means "over 50%". (This aspect of the question is somewhat LSAT-like.) The fact that children consume "most" of the pizza and cookies does not eliminate the remaining amount of pizza and cookies as a cause for the parents' high fat intake, and it does not present any alternative cause.

Nice question. This proved we need to read the question more carefully.
"most seriously weaken this explanation of the parents' higher fat intake" - this is asking which statement would weaken the explanation of parent's higher fat intake and not the statement that weakens the arguement as a whole.
Great explanations from all of you.
