Which of the following can be correctly inferred from the statements above?


A. Individuals who stretch and drink 64 ounces of water each day do not run any risk of injury from physical activity.

B. Individuals who do not stretch regularly or drink enough water have a high risk of injury from physical activity.

C. A regimen of stretching and drinking at least 64 ounces of water is the best way to improve performance during physical activity and to reduce the risk of injury from such activity.

A.Individuals who stretch and drink 64 ounces of water each day do not run any risk of injury from physical activity.

Any risk of injury cannot be assumed or inferred there is a possibility that the person may run a risk of injury - inference is something that also must be true when you infer it - A out

B.Individuals who do not stretch regularly or drink enough water have a high risk of injury from physical activity.

High risk or low risk is not stated in the argument and may or may not be true

C.A regimen of stretching and drinking at least 64 ounces of water is the best way to improve performance during physical activity and to reduce the risk of injury from such activity.

BEST - it may be a way to imporve performance but may not be the BEST way

D.A program of stretching and drinking at least 64 ounces of water will improve the performance of some individuals during physical activity.

It clearly states that "in some individuals if those individuals " so some individuals will improve the performance

E.Only stretching is required to lengthen a person's muscles

ONLY superlatives not sure if this is the only way and it would go beyond the scope of the argument to assume it - E out

How can we relate "some individuals" to "those" in the stimulas..?
I am getting confused regarding use of Some in the answer choice....

Passage says that "Muscles can be lengthened in some individuals if those individuals stretch and drink at least 64 ounces of water everyday". As it does include some here, it should justify the use of "some" in D.

completely agree with metallicfan.. esp for option C which is a good trap option.

Premise 1:- Increases in the length of a person's muscles have been shown to improve performance during physical activity and to reduce the risk of injury from such activity.
Premise 2:- Muscles can be lengthened in some individuals if those individuals stretch and drink at least 64 ounces of water everyday.

Which of the following can be correctly inferred from the statements above?

(A) Individuals who stretch and drink 64 ounces of water each day do not run any risk of injury from physical activity. - This broadens the scope not all individuals can achieve this as per the premises stated above hence not the correct answer.
(B) Individuals who do not stretch regularly or drink enough water have a high risk of injury from physical activity - Incorrect. The premises states that drinking water stretching is one of the way to lengthen muscles in some of the individuals.
(C) A regimen of stretching and drinking at least 64 ounces of water is the best way to improve performance during physical activity and to reduce the risk of injury from such activity. - The argument does not state that this is the best way since this choice contains extraneous info this is incorrect.
(D) A program of stretching and drinking at least 64 ounces of water will improve the performance of some individuals during physical activity - Perfect! This program can result in improved performance in "some" individuals. This does not generalize rather it merely connects premise 1 and premise 2 to form a valid inference / conclusion.
(E) Only stretching is required to lengthen a person's muscles. - Incorrect as it omits other possibilities.

A.Individuals who stretch and drink 64 ounces of water each day do not run any risk of injury from physical activity. too ambitious
B.Individuals who do not stretch regularly or drink enough water have a high risk of injury from physical activity. not necessarily, we only know that stretching and drinking an adequate amount of water reduces the risk of injury...it could already be low
C.A regimen of stretching and drinking at least 64 ounces of water is the best way to improve performance during physical activity and to reduce the risk of injury from such activity. this is too ambitious- the stimulus only provides information to support that it is a possible way but stimulus does not provide information about the relative efficacy of this regiment
D.A program of stretching and drinking at least 64 ounces of water will improve the performance of some individuals during physical activity. yes this answer is a realistic conclusion
E.Only stretching is required to lengthen a person's muscles
we can prove or disprove this so no

The question asks for something that "can be correctly inferred," making this an Inference question.

According to the stimulus, some people can lengthen their muscles by stretching and drinking a certain amount of water each day, and lengthened muscles improve physical performance and reduce the risk of injury from physical activity.

It's often hard to predict an answer to Inference questions, but think about what you're given here. There's a plan to lengthen muscles and a benefit to be had from it; the right answer will likely point out that if some people follow the plan, they'll get the benefit.

Correct choice (D) states that engaging in stretching and water drinking can improve the physical performance of some people. The word "some" is key--it can't be concluded that all people can benefit from stretching and drinking enough water, because only some people can lengthen their muscles from this sort of a regimen.

(A) and (C) are extreme. There's not enough information to say that those who stretch and drink water do not run any risk of injury--just that some people who do so will lower their risk. Nor is there enough information to say that stretching and drinking water is the best way to increase performance and reduce the risk of injury--just that it is one way of doing so.

(B) also does not follow from the statements given. Just because the risk is lowered for some who stretch and drink 64 ounces of water daily, it does not have to be true that those who do not engage in such activity have a high likelihood of injury.

(E) is also unsupported. A program of both stretching and drinking 64 ounces of water can lengthen muscles; either alone may not be effective.

In C it says its the best way--- this is something we cannot infer from the statements.

Only D makes sense
