Moderate exercise lowers the risk of blockage of the arteries due to blood clots, since anything that lowers blood cholesterol levels also lowers the risk of hardening of the arteries, which in turn lowers the risk of arterial blockage due to blood clots; and, if the data reported in a recent study are correct, moderate exercise lowers blood cholesterol levels.

The conclusion drawn above follows logically if which one of the following is assumed?

(A) The recent study investigated the relationship between exercise and blood cholesterol levels.
(B) Blockage of the arteries due to blood clots can be prevented.
(C) Lowering blood cholesterol levels lowers the risk of blockage of the arteries.
(D) The data reported in the recent study are correct.
(E) Hardening of the arteries increases the risk of blockage of the arteries due to blood clots.

IMO C

Moderate exercise lowers the risk of blockage of the arteries due to blood clots, since anything that lowers blood cholesterol levels also lowers the risk of hardening of the arteries, which in turn lowers the risk of arterial blockage due to blood clots; and, if the data reported in a recent study are correct, moderate exercise lowers blood cholesterol levels.

MC--> lower risk of artery blod clot -.................low Blood cholot-->low hard of arte -> low artey blood clot
MC--> blod cholo level

prethink : Option C fits correctly

...please suggest as the OA marked is D

Seems to be an indigestable OA.

The statement mentions that the data given is correct. I chose E.

Mod E (moderate exercises) -> lowers risk of artery blockage due to blood clots.

Anything (x ) -> lowers hardening of artiries -> lowers artery blockage because of blood clots
-> lowers cholestrol levels.
Conclusion: Mod E lowers Cholestrol levels
Meaning X is Moderate Exercises.

Though I was not sure about E too, but it seems to attack one part of causation. But I thought that the option E somehow strengthens the causation in bold and hence it gives support. If we negate it :
"Hardening of the arteries DOES NOT increase the risk of blockage of the arteries due to blood clots." -> then the causation fails but again I agree, this is the premise and not the conclusion I am attacking.

Can anyone please shed some light by sharing OE ?

Could you give this one a shot? The current answer split looks like the community is having quite a bit of struggle with this one.

D is wrong.Definitely.100%.

"If the data represented is correct" in the question obviously makes D wrong.

Official Explanation by Kaplan


Assumption
“Since” signals evidence, and “…, since” signals that the conclusion preceded the comma.

You have to shuffle the clauses around a bit to see it, but the logic is tight as a drum if the study
data are correct. If they are, then moderate exercise lowers blood cholesterol, which lowers the risk of
hardened arteries, which lowers the risk of blood clots causing arterial blockage. Again, that’s all
speculative based on the “if,” But since the conclusion (clause #1) definitively asserts that last lowered
risk, the author must be assuming (D) that the “if” is true and that the data are correct.

(A) doesn’t meet the definition of an assumption (“unstated evidence the author takes for
granted”), because the nature of the study is asserted explicitly in the final sentence. Prevention of arterial
blockage (B) isn’t necessarily the same as “lowered risk,” and even if it is, (B) is stated in the opening
sentence, not implicit. (C) is stated, too, in the second clause of the stimulus. And the author need not
be taking for granted what hardened arteries do (E) since every fact cited is about lowering risks, not
raising them.


I think (C) cannot be the answer because it is already mentioned in the argument. This is a common trap in the "find assumption" type questions. One of the premises in the argument is re-worded to form an option and the trap is that since it is already a premise it cannot be the assumption. (which is an unstated premise that is essential for the sanctity of the argument)

Hope it helps.

Arro44 and Gladiator59,

This question is not the type of assumption question you would see on the GMAT. This type of LSAT question is called a pseudo-sufficient (fake assumption) question. It is more of a paradox resolve/strengthen/weaken question than anything else. You cannot negate these answer types to get your answer.

I hope this resolves the issues that people are having with it.

(B) Blockage of the arteries due to blood clots can be prevented.
(C) Lowering blood cholesterol levels lowers the risk of blockage of the arteries.

Premises:

anything that lowers blood cholesterol levels also lowers the risk of hardening of the arteries,
Lower risk of hardening of the arteries lowers the risk of arterial blockage due to blood clots;

Conclusion: Moderate exercise lowers the risk of blockage of the arteries due to blood clots

Note the leap we have made. The premise says that "if the data reported are correct", moderate exercise lowers cholesterol. But we have concluded that moderate exercise does lower the risk of blockage.

The argument goes like this:
If A, B lowers C,
C lowers D.
D lowers E.

Hence, B lowers E.

But hey, the argument says "if A, then B lowers C"
But we are concluding that B does lower E. Hence we are assuming that A is correct.
So we are assuming that the data reported are correct.

If data reported are not correct (negate the assumption), then B doesn't necessarily lower C. Then can we say B lowers E? No. It may or may lower E. So our conclusion fails.

VeritasKarishma,

Happy new year.

In the argument, it is already mentioned that "if the data reported in a recent study are correct". Shouldn't we go by the rule that an assumption is an unstated part of the argument, which binds the premise and conclusion?

Please advise.

I believe you are right. The argument is already logical. If... Lowers, else we do not know. So this is already stated in the argument.

Let's make it simple

If Mary loves me, she has good taste.

the assumption cannot be "Mary loves me" because it is already in the argument.

If we negate the assumption, the argument is still true.

She does not love me - The argument "If Mary loves me, she has good taste" is still true.
