Calorie restriction, a diet high in nutrients but low in calories, is known to prolong the life of rats and mice by preventing heart disease, cancer, diabetes, and other diseases. A six-month study of 48 moderately overweight people, who each reduced their calorie intake by at least 25 percent, demonstrated decreases in insulin levels and body temperature, with the greatest decrease observed in individuals with the greatest percentage change in their calorie intake. Low insulin level and body temperature are both considered signs of longevity, partly because an earlier study by other researchers found both traits in long-lived people.

If the above statements are true, they support which of the following inferences?

(A) Calorie restriction produces similar results in humans as it does in rats and mice.

(B) Humans who reduce their calorie intake by at least 25 percent on a long-term basis will live longer than they would have had they not done so.

(C) Calorie intake is directly correlated to insulin level in moderately overweight individuals.

(D) Individuals with low insulin levels are healthier than individuals with high insulin levels.

(E) Some individuals in the study reduced their calorie intake by more than 25 percent.

E... "atleast 25%" and "greatest percent".

I will go with E as well.

a. Calorie restriction produces similar results in humans as it does in rats and mice.
-Just because some of the results are similar we cannot inference that all results are similar.

b. Humans who reduce their calorie intake by at least 25 percent on a long-term basis will live longer than they would have had they not done so.
- This is close. While from the argument it should be true. However we cannot make a blanket stmt for all human beings. There could be other reasons not mentioned in the argument why someone who has reduced calorie intake by atleast 25% could die earlier.

c. Calorie intake is directly correlated to insulin level in moderately overweight individuals.
-Insulin level can also increase owing to other reasons not mentioned in the stmt.

d. Individuals with low insulin levels are healthier than individuals with high insulin levels.
-Just because humans are likely to live longer does not gurantee that they will be healthier.

e. Some individuals in the study reduced their calorie intake by more than 25 percent.
- This is paraphrasing of the stmts already made in the argument and hence can be certainly infrenced.

E is a poor inference. It should have said "All individuals in the study blah blah"

A six-month study of 48 moderately overweight people, who each reduced their calorie intake by at least 25 percent,

But others dont make much sense either. I am a little confused.

I'll go with (A).

How can it be (E)???

Atleast 25 % does not mean necessarily greater than 25 % ..............may all the subjects reduced their calorie intake by exactly 25%.

But it also says higher the calorie reduction better the results are. Doesnt that mean there were atleast a few people who had reduced their intake by greater than 25%

Did not like this Q.

Does not tell whether Humans also take nutritious diet while reducing calories.

A & B does not need to be true

Same with D

Now C & E remain.

C see green above; makes sense but direct co relation means directly proportional?? So that means increase corresponds with increase and decrease with decrease. We only know about decrease and not increase.

E see blue above; Safe to say E.

Hence E, but this Q gives a load of information and then wants you to pick the most obvious answer. It still could be C, if I am thinking too much about the direct co relation

e. Some individuals in the study reduced their calorie intake by more than 25 percent.


IMO D

the question says:

· Calorie restriction prolongs rats' life by preventing diseases.
· A study over humans determined that calorie restriction is directly related to low insuline and body temperature, which are considered signs of longevity.

A out: this is an assumption
B out: the results of the study may not apply to others
C out: just moderately overweight individuals?
E out: already mentioned in the question

OA and Source?

Cheers

I'll go with B

c)I don't think this is right because reduced calorie intake may cause lower body temperature, which in turn may cause reduced insulin. This shows it is indirectly related
d)Not correct because this addresses only one condition - lower insulin but not the other condition - lower body temperature
e)Again not right because all the persons in the test group may have reduced the calorie intake by exactly 25%. This statement doesn't contradict any of the conditions in the argument

Between B and A I'll go with B because A talks about increasing the life span by mentioning some diseases. B on the other hand talks only about insulin and body temperature

Will go with B
