### HideShow timer Statistics

Although most people know that exercise is good for the body, few realize the extent to which it is valuable to the mind. The blood circulates more rapidly after physical exertion, thus allowing all of the body’s organs to operate more efficiently. This increased activity enables the brain to receive more oxygen, thereby creating a higher capacity for concentration.

The main point in the argument above is that

(A) the greater the amount of oxygen the brain receives, the better the brain functions.
(B) exercise is a mental, as well as physical, activity.
(C) exercise helps the brain more than it does the rest of the body.
(D) people can greatly improve their powers of concentration by exercising more often.
(E) exercise serves more than one purpose

Can anyone suggest how to approach this CR .I was confused between two options !!!

I would say E is way too generic. more than one purpose of what???

few realize the extent to which it is valuable to the mind (good enough to say mental activity??) and then it goes on to explain how the brain gets better.

Most people know that it is already a physical activity. The argument just explained that its good for the mind as well. Cant we say it Exercise is a mental as well as physical activity.

IMO E.

B and E both look fine, but b says that exercise is mental and physical activity.. which the passage does not state

OA is E,
Reason why B is wrong is that there is noting discussed about physical activity ,its just the author starts the argument to give a statement ,exercise is good for body ,then gives others +ve points of exercise....but does not prsent what activities are done mentally or physicallyto do exercise.

hence E is perfect

First, I chose D, but after reading the post, realized that D is only a supporting argument. The main argument is E.

The main point in the argument above is that

(A) the greater the amount of oxygen the brain receives, the better the brain functions.
Though this is true it is not the sole purpose of the stimulus. It is something that is inferred from the last sentence.
(B) exercise is a mental, as well as physical, activity.
No where in the stimulus does it mention the mental or physical demand exercise requires
(C) exercise helps the brain more than it does the rest of the body.
This is an extreme statement and no where in the stimulus does it state this.
(D) people can greatly improve their powers of concentration by exercising more often.
Though this is possible it is not the main point of the article. Concentration is improved but it does not go into detail the extent of the concentration.
(E) exercise serves more than one purpose
The stimulus is about exercise and the word "although" in the stimulus suggests that even though it is good for the body as most people are aware it actually helps stimulate the mind too.

I chose E

Can anyone suggest how to approach this CR .I was confused between two options !!!

A) is incorrect because from the information in the passage the stimulus of the brain isn't the onl purpose of the short passage

B) is wrong: is not relevant

C) is wrong: all body have benefits, not only brain

D) is wrong: is true, but concentration increase more with excercises but also by sleep, Omega 3 and so on........not only by fitness although is one of the better way

There is very subtle difference between D & E

If we rephrase the Argument , then " exercise helps physical and concentration"
