Caffeine must be as beneficial for weight loss as exercise. After all, when a person consumes caffeine the chemical stimulates his or her metabolism in almost the exact same way as the body does when that person is involved in physical exercise.

The argument above requires which of the following assumptions?


A. The body’s short-term response to any stimulant is an effective measure of that stimulant’s long-term effect on the body.

B. The consumption of caffeine is an effective way for a person to control his or her weight.

C. Caffeine has no negative side effects for a person’s health.

D. The effect an activity has on the body’s metabolism level is an adequate measure of how that activity will affect weight loss.

E. A person who consumes caffeine is unlikely to supplement that consumption with physical exercise or other methods of weight loss.

Question Type: Assumption

Argument: Caffeine must be as beneficial for weight loss as exercise because caffeine stimulates metabolism in the same way as exercise does.

A. The body’s short-term response to any stimulant is an effective measure of that stimulant’s long-term effect on the body. - Irrelevant. We are not worried about the short term or long term effect of Caffeine as a stimulant.

B. The consumption of caffeine is an effective way for a person to control his or her weight. - Out of focus. Focus is not on whether caffeine is an effective way to lose weight. Focus is more on comparison between the weight loss caused by caffeine consumption and that caused by exercise. Also, negating this choice doesn't affect the conclusion of the argument.

C. Caffeine has no negative side effects for a person’s health. - Irrelevant.

D. The effect an activity has on the body’s metabolism level is an adequate measure of how that activity will affect weight loss. - Correct.

E. A person who consumes caffeine is unlikely to supplement that consumption with physical exercise or other methods of weight loss. - We cannot make out whether caffeine consumption is beneficial for weight loss. Negating E, doesn't affect the conclusion.

Conclusion - Caffeine consumption and exercise both produce metabolism in almost the same way hence caffeine consumption must reduce weight just as exercise does.
Just negate D and see how it kills the argument.
If the effect that caffeine consumption will have on body's metabolism is not an adequate indicator of how that will affect weight loss then this argument will cease to exist.

VERITAS PREP OFFICIAL SOLUTION:



D. Consider the gap in the argument’s logic – the premises all deal with the stimulus of metabolism, but the conclusion is about weight loss. In order for the argument to be valid, these items – metabolism and weight loss – would need to be connected. And only answer choice D connects metabolism with weight loss. Choice A gets close, but “long-term effect” doesn’t necessarily mean “weight loss”. Choice B isn’t required, as the argument isn’t saying that caffeine is effective, as a whole, just that it’s as effective as exercise (which, based on the facts presented, may or not be effective). Choice C isn’t required, as it goes outside the scope of the conclusion. And choice E is also incorrect as the conclusion only compares exercise and caffeine, it doesn’t attempt to link them together as simultaneous weight loss methods.

Dear @GMATGuruNY,

Can you shed light why D is correct while E is wrong?

Choice E negated: A person who consumes caffeine is likely to supplement that consumption with physical exercise or other methods of weight loss.[/quote]

Here, the wight loss is not Only due to experiences which shatter the conclusion.

Where did I go wrong here?

Thanks

Mo2men,

D is most certainly correct here. Let us review:

Caffeine must be as beneficial for weight loss as exercise. After all, when a person consumes caffeine the chemical stimulates his or her metabolism in almost the exact same way as the body does when that person is involved in physical exercise.


Green = Conclusion
Blue = Premise

The argument above requires which of the following assumptions?

D. The effect an activity has on the body’s metabolism level is an adequate measure of how that activity will affect weight loss. -- Negated, this says metabolism is not a measure. When we look at the premise, this says that metabolism is equal for coffee and working out. Hence, the conclusion rests upon this premise.

E. A person who consumes caffeine is unlikely to supplement that consumption with physical exercise or other methods of weight loss. -- This says that a person who drinks coffee also works out. How does this create a comparison between the two? It doesn't. How does it smash our conclusion? It doesn't. It just talks about them going hand in hand, so we cannot know how they affect weight loss.


Does this help?

E. A person who consumes caffeine is unlikely to supplement that consumption with physical exercise or other methods of weight loss.


Premise: Caffeine stimulates metabolism the same way as exercise.
Conclusion: Caffeine must be as beneficial for weight loss as exercise.

The argument above is valid only if there is a link between METABOLISM and WEIGHT LOSS.
Apply the NEGATION TEST.
When the correct answer is negated, the conclusion will be invalidated.

D, negated:
The effect an activity has on the body’s metabolism level is NOT an adequate measure of how that activity will affect weight loss.
Here, the link between metabolism and weight loss is broken, invalidating the conclusion that -- because caffeine stimulates metabolism -- it must be beneficial for weight loss.
Since the negation of D invalidates the conclusion, D is an ASSUMPTION: a statement that MUST BE TRUE for the conclusion to hold.

When E Is negated, it is still entirely possible that the consumption of caffeine will lead to weight loss, since -- according to the premise -- caffeine stimulates the metabolism the same way as exercise.
The negation of E offers no information about the effect of caffeine on its own.
Since the negation of E does not invalidate the conclusion, eliminate E.

Mo2men Straight D When we negate Option E our conclusion does not falls apart as caffeine consumption can still lead to weight loss on its own. Option D provides us the missing link between premise and conclusion. If you negate Option D our conclusion shall fall apart as our stem is based on chemical metabolism as it has the same effect on the body in both the cases i.e. Consumption of Caffeine and doing exercise

Hope this helps....Kindly give kudos if this helps :-)
