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.


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.

The conclusion is 'more fat intake' and 'eating pizza/snacks' is the premise...test it if you ppl want.. 'since they eat more pizza/snacks they are more fat'. So, we have to choose an option that would effect conclusion. B provides an 'alternate explanation' in the sense 'if pizza doesn't makes you fat, milk would do that'. But ultimately they are becoming fat...Also, its mentioned they 'purchase' & not 'consume' which are completely different in meaning. C says 'children consume more pizza'...so how come ppl with children will become more fat compared to ppl with no children?? I'll go with C..astalavista...

I picked C even though it was not very convincing.

I immediately eliminated B because it states that parents PURCHASE more milk. Nowhere does it say that they actually consume this milk. Maybe children drink all the milk? Or am I missing something here?

B states that household purchase more whole milk. Nowhere it is said that they consumed. May be children consumed all purchased whole milk (In fact, it happened to my family.)

For D, sometimes it happens that children motivate to eat seeing their parents' eating. So, to encourage children who are reluctant to eat, parents need to intake some fatty food necessary for children. So, this could be an weakener. (I am not sure whether this could be! Just speculating)
