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

Dont have the OA but lets discuss.logic is not that tough.


I would go with B. If the households with children purchase more whole milk, which has a high fat content, it weaken the conclusion that the high fat intake is attributed to the snacking of pizza and cookies. It could be well from the milk. All other answer choice does not have the impact to the conclusion.

My choice is B. 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.

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.

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.

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.

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.


OFFICIAL EXPLANATION


The first sentence is a premise, which we can take as a statement of fact. The second sentence is a claim made by the author: that the source of the extra fat grams is pizza and cookies. We are asked to weaken this claim; note that we need to tear down the conclusion, not the premise.

(A) Strengthen. This choice supports the conclusion with evidence that households with children tend to have more pizza and cookies present.

(B) CORRECT. Weaken. This choice presents whole milk as an alternative source for the extra grams of fat, and thereby weakens the conclusion that the extra fat must be from pizza and cookies.

(C) Irrelevant. Children may consume most of the pizza and cookies, but the remainder could be consumed by their parents. This answer choice does not provide enough information to address the conclusion that the adults eat more pizza and cookies than they would if no children were present.

(D) Irrelevant. This argument starts with a premise about what parents actually do, and attempts to explain their behavior. Statements about what parents ought to be doing are not relevant to the argument.

(E) Irrelevant. This argument is about how to explain the higher fat intake of the average parent living with children. The fact that some parents are not average is both unsurprising and irrelevant.

Eliminate everything except B and C.

B gives another reason for more fat consumption. It weakens the argument.
C says that children consume the most. Most means >50% . That is all. It does not weaken the argument.

B is right.

while solving weakening question two things or process will be given and both will be connected , we need to show in option that things or process are not connected .

A -- 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.
B - -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.

Analysis as it is a weakening question we need to find option that shows that B is not happening because of A .


(A) On average, households with children spend $15 more per week on pizza and cookies than do households without children. - not useful for our argument.
(B) Households with children purchase much more whole milk, which has a high fat content, than do households without children.- wait it gives different reason for B . so we can keep this option.
(C) Children consume most of the pizza and cookies in any given household. - this option is a trap . it's possible that quantity of pizza in food is in excess so even though children consume it , left over quantity is still consumed by parents.
(D) Parents ought to set a good example for their children, in dietary choices as in other matters.- out of scope.
(E) Not all parents living with children consume more grams of fat than do adults living without children.- out of scope.
