Something seems wrong about the explanation in KAPLAN for this question. Would like your opinions-

"According to a recent study, a diet that is free of meat and dairy products greatly reduces the risk of suffering a heart attack. The study cites the fact that only 10 percent of those who consume such a diet suffer a heart attack at some point in their lives.

Which of the following would most seriously weaken the argument above?

A) Diets free of meat and dairy are low in calcium, which can lead to bone density decreases
B) Those who consume only dairy but not meat are twice as likely to suffer a heart attack as those who consume neither meat nor dairy
C) Some people who consume neither dairy nor meat suffer two or more heart attacks over the course of a lifetime
D) Meat and dairy products are high in low-density cholesterol, which is known to harden arteries and cause other heart problems
E) Of those who consume dairy and meat, 7 % regularly suffer heart attacks over the course of their lifetime"

My answer is A, however KAPLAN says E. Can anyone please explain (not the same explanation as KAPLAN)

The highlighted part of the stimulus is the main conclusion which we have to weaken.

Food - ( Meat + Dairy Products ) = Reduced risk of Heart Attack.

The blue highlighted part refers to those who consumes diety free of meat and dairy products.

Let there be 100 people who consumes diety free of meat and dairy products.
Out of those 100 people 10 suffer from a heat atatck and 90 doesn't suffer from a heart attack.

Since Only 10% suffer from a heat atatck we are led to believe that consuming diety free of meat and dairy products will not lead to heart attack.


Now lets's explore all the options.

A) Diets free of meat and dairy are low in calcium, which can lead to bone density decreases

Out of scope and irrelevant

B) Those who consume [color=#ff0000]only dairy but not meat are twice as likely to suffer a heart attack as those who consume neither meat nor dairy


Comparing risk of heart attack without any data , hence is not a good option.

C) Some people who consume neither dairy nor meat suffer two or more heart attacks over the course of a lifetime

Reduces the arguement to subsets of those who consume neither dairy nor meat products , without weakening the conclusion.

D) Meat and dairy products are high in low-density cholesterol, which is known to harden arteries and cause other heart problems

Strengthens the conclusion instead of wekening it.

E) Of those who consume dairy and meat, 7 % regularly suffer heart attacks over the course of their lifetime"

This reduces the arguement to the risk of heart attacks as -

Consuming dairy and meat products ( 7% ) < Consuming food free of dairy and meat products (10%)

This refers to the conlcusion that people consuming food free of dairy and meat product has a greater chance of heart attack than those who consumes dairy and meat products , which clearly weakens the arguement.

Hence answer is (E)

A addresses bone density issues which have nothing to do with heart attacks. E discusses heart attacks and shows that those who maintain a diet that includes dairy and meat actually have a lower rate of heart attack (7% as compared to dairy and meet-free diets' rate of 10%). This fact hurts the argument. At first you think "Oh, 10%, that's really low. Sounds like a great idea!" but then you realize that if you do eat dairy and meet, you'd lower that percentage from 10% to 7% you're better off. That undermines the conclusion in the stem.

Yeah, I do understand bone diseases have nothing to do with heart attacks, however, it shows not having a diet with meat and dairy can also lead to some other problems. For E, at the time solving the question, I felt "regularly suffer heart attacks" is a little strong.

Easy choice E show that eating dairy and meat help people healthier than not eating (diet). Therefore, the usefulness of diet is broken.

Choice A is irrelevant becauz it talk about bone density that is out of scope.

I don't understand how E is the answer. It states that 7% of the people regularly get heart attacks. What abt the others? They might not suffer from regular bouts but they might def get 'a' heart attack. The conclusion clearly states that a diet free of diet and meat reduces the chance of 'a' heart attack. C is not strong but is clearly the more feasible option here.

I think that E is correct.
'...the fact that ONLY 10% suffer a heart attack at SOME POINT in their lives ' means that nobody else experience a heart attack at all, but 10% do it at least once.
E indicates that '7% REGULARLY suffer heart attacks'. So, we may conclude that actually 10% suffer h.a. at some point , and there are other people who experience them more than once (regularly).

A is irrelevant. It says nothing about h.a. We don't care about other desease.

Please correct me if I am wrong, but I still have problems with E. I believe pretty much the only way E can be right is if we assume that on top of 10% who have "a heart attack" there is additional 7% who have regular heart attacks. Thus, the total number of people who suffer a heart attack either once or many times is 17%.

However, the problem with such reasoning is that "only 10 percent of those who consume such a diet suffer a heart attack at some point in their lives" is not equivalent to "only 10% suffer heart attack only once in their lives". It actually makes you believe that "only 10% suffer a heart attack at least once".

Please correct me if I am wrong.

I typically do not understand this kind of questions/answers. the only think I know from now on for the GMAT CR is that we need to pay attention to the words and here saying that 7% suffered 2 or more heart attacks does not help us in the argument concerning "a hear attack" ! maybe 20% of regular eater suffered a heart attack, among which 7%...
I am lot better for quant section and I have trouble to understand when we have to take care of the words in themselves ("only", "no",...) in answers or not. Here I answered C which was the best answer I thought and quite the opposite of the true OA. Could you explain that to me ?
Thanks !

Passage Says : only 10% of People who eats diet free of diary and meat products suffer from HA.

Lets say there are 100 people who eat diet free of diary and meat products
of this 10 people suffer from Heart Attack.

Now, we have to weaken this argument.
This can be done by providing proof that No. or % of people who eat dairy product and suffer from Heart Attack is less that above category.
Which is exactly what Option E is saying.

Only 7% who eat meat and diary product suffer from Heart Attack. (Which is 7 on a scale of 100)

Hope this helps ...
Kudos if you the solution and method....
