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.
