### HideShow timer Statistics

A recent study indicates that people who keep their workout records are far more successful at achieving their fitness goals than people who don’t keep track of their workout. Experts believe that many fail to achieve their fitness goals because they burn fewer calories than they intend to burn. One study followed a group of gym-members who reported that they could not achieve their fitness goals when burning 700 calories a day. The study found that the group burned, on average, 60% fewer calories than it claimed. In contrast, when people record their exercises, their actual calories burned more closely matches their reported calories burned.

The two boldface portions in the argument above are best described by which of the following statements?

A. The first is an example illustrating the truth of a certain theory; the second is a competing theory.
B. The first is an explanation of why a certain theory is thought to be true; the second is an example of research results that support this theory.
C. The first is a conclusion reached by experts; the second is evidence that that conclusion is correct.
D. The first introduces a theory that the experts have disproved; the second is the basis for the experts’ argument.
E. The first is a premise upon which the experts base their opinion; the second illustrates that their opinion is correct.

Official Solution:

A recent study indicates that [b]people who keep their workout records are far more successful at achieving their fitness goals than people who don’t keep track of their workout.
Experts believe that many fail to achieve their fitness goals because they burn fewer calories than they intend to burn. One study followed a group of gym-members who reported that they could not achieve their fitness goals when burning 700 calories a day. The study found that the group burned, on average, 60% fewer calories than it claimed. In contrast, when people record their exercises, their actual calories burned more closely matches their reported calories burned.

The two boldface portions in the argument above are best described by which of the following statements?
[/b]

A. The first is an example illustrating the truth of a certain theory; the second is a competing theory.
B. The first is an explanation of why a certain theory is thought to be true; the second is an example of research results that support this theory.
C. The first is a conclusion reached by experts; the second is evidence that that conclusion is correct.
D. The first introduces a theory that the experts have disproved; the second is the basis for the experts’ argument.
E. The first is a premise upon which the experts base their opinion; the second illustrates that their opinion is correct.

The conclusion of this argument is that“many people do not achieve their fitness goals because they burn fewer calories than they intend to burn.”The first boldface portion is a factual premise that there is an observed correlation between keeping a workout record and achieving fitness goal. This premise supports the experts’ conclusion. The second boldface portion is another supporting premise, which provides a specific study indicating that people who do not keep a workout record burn far fewer calories than they realize.
1. The first boldface is a fact that supports the experts’ theory, but it does not illustrate the truth of that theory; however the second boldface does. The second boldface is a fact that supports the experts’ theory; it is not a competing theory.
2. The first boldface is a fact that supports the experts’ theory, but it does not explain why their conclusion is correct.
3. The first boldface is not the conclusion; it is an observation, i.e. a fact. The second boldface is evidence that the experts’ conclusion is correct, but not the evidence that proves that the first boldface is correct.
4. The first boldface is a factual statement, not a theory. Moreover, the first boldface supports the theory of the experts; it is not something they have disproved.
5. Correct. The first boldface is a basis for the experts’ conclusion that many fitness efforts fail because people burn fewer calories than they intended. The second boldface directly illustrates how fitness efforts of a certain group failed for the same reason.

I think this question is poor and not helpful.
The answer to this question is questionable. In my opinion, the 2nd answer choice is correct. GMATClub has the answer listed as answer choice #5, however, in that answer choice it states "the second illustrates that their opinion is correct." To say that the second portion in boldface shows that the theory is correct is an assumption in itself and is too strong an assertion and, in my opinion, is wrong. Looking at the paragraph, the second portion in boldface only supports the theory that the scientists have (which is how answer choice #2 describes it), it does not confirm that the theory is correct.

I don't agree that the conclusion of the argument is "many people do not achieve their fitness goals because they burn fewer calories than they intend to burn". I believe that BF1 is the main position of argument. The final sentence "when people record their exercises, their actual calories burned more closely matches their reported calories burned." confirms that i feel.

The conclusion that we are talking about is that of the Experts and since BF1 is result of a survey, it is not the conclusion of Experts.

Somebody please correct me if I am wrong but I think we can Cross Off B because BF1 is not the explanation of the Theory. As a matter of fact, it CANNOT be the Explanation as the Theory presented by experts is based on that result. Thinking about chronology,

Result of Study -> Theory by Experts -> Explanation/Another study.

We explain After we make a claim and not before it. So, Results of Study cannot be the explanation of Theory.

Wrong, it is the result of a study.

Can someone please clarify why it is a premise and not a conclusion?

I do not agree that the first boldface is a premise and not the conclusion.

Let me share my thoughts on this.( i was able to eliminate C)

(a)
Because A recent study indicates that people who keep their workout records are far more successful at achieving their fitness goals than people who don’t keep track of their workout. Therefore, Experts believe that many fail to achieve their fitness goals because they burn fewer calories than they intend to burn.

But if you rotate this

(b)
Because Experts believe that many fail to achieve their fitness goals because they burn fewer calories than they intend to burn. Therefore A recent study indicates that people who keep their workout records are far more successful at achieving their fitness goals than people who don’t keep track of their workout.

the second part of (b) could have used to keep a point, not the other way around

Generally a fact follows the opinion, Done in (a).

Let me know if this helps in some way.
