Studies have shown that people who keep daily diet records are far more successful at losing weight than people who don’t keep track of what they eat. Researchers believe that many weight-loss efforts fail because people eat more calories than they intend to consume. One study followed a group of patients who reported that they could not lose weight when consuming only 1,200 calories a day. The study found that the group consumed, on average, 47% more than it claimed and exercised 51% less. In contrast, when dieters record what they eat, their actual consumption more closely matches their reported consumption.

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

(A.) The first is a conclusion reached by researchers; the second is evidence that that conclusion is correct.
(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 an example illustrating the truth of a certain theory; the second is a competing theory.
(D) The first is a premise upon which the researchers base their opinion; the second illustrates that their opinion is correct.
(E) The first introduces a theory that the researchers have disproved; the second is the basis for the researchers’ argument.

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

A. The first is a conclusion reached by researchers; the second is evidence that that conclusion is correct.
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 an example illustrating the truth of a certain theory; the second is a competing theory.
D. The first is a premise upon which the researchers base their opinion; the second illustrates that their opinion is correct.
E. The first introduces a theory that the researchers have disproved; the second is the basis for the researchers’ argument.


The paragraph starts with the reference to studies that point to the same conclusion. Then it discusses a particular study that is in line with the studies that are mentioned in the beginning.

A - the first is not a conclusion reached by the researchers. Even if it is, the second is not the evidence. Second is the result of a different independent study.

D - is the right choice. First is a premise that the researchers start with. Then the second is the result that proves that their opinion is correct.

IMO D since the first part is a premise and the 2nd part is an illustration to support it.

I don't agree with D.
Although the first part is a premise, there is not an opinion. The researches are just reporting a finding in a study.

What is the source please?

I chose A too. Wouldn't it be a conclusion if I said "Studies have shown that without water life could not be sustained". Lastly, "The study found that.." makes it sound like evidence.

I do see how D could be correct. Can you tell me the source of this question?

Since the second part is not the evidence but finding . A is not correct.

the only left choice is D .

even am not convinced 100%, but the best answer is D.

I initally chose A as well, but I can see why D is correct.

When "Studies show" something, that means its a fact/premise. I agree that this is not an opinion. But the next sentence "Researchers believe that many weight-loss efforts fail because people eat more calories than they intend to consume" is definitely an opinion or theory.

And the 2nd boldface does illustrate that their theory/opinion is correct.

Good question.

I picked B. My reasoning is this: The theory according to me is mentioned in this line: "Researchers believe that many weight-loss efforts fail because people eat more calories than they intend to consume." The first bold faced line is the explanation for that theory.
The line, "One study followed..." indicates that this is just one such example of a research finding. Therefore the second statement indicates an example of a study that contributes to the theory.

I feel you would be right if the "Researchers believe..." was bolded. But the question asks about the "people who keep a daily journal...".

This is a trick to see if you are paying attention to the question. If the question was an argument style question where nothing was bolded, then that answer could be right.
