### HideShow timer Statistics

Marketer: While running is one of the most efficient forms of exercise for losing weight, many would-be runners are unable to participate due to the joint pain – particularly in knees and ankles – that they experience while running. With our reduced-gravity treadmill, these people can derive the full weight-loss benefit of running without the intense joint pain.

Which of the following, if true, would most weaken the argument above?

(A) Most avid runners greatly prefer running outdoors to running on a machine.

(B) Experts believe that swimming, not running, is the most effective form of exercise for those looking to lose weight.

(C) A reduced-gravity treadmill can alter one’s natural running stride, leaning to muscle and tendon strain issues.

(D) While reduced gravity can lessen the severity of joint pain, those who experience pain from prior injuries will likely feel some joint pain while using a reduced-gravity

(E) Much of the weight-loss benefit from running is derived from a runner having to carry his own body weight across a long distance.

I was stuck b/w c and e.
After reading the last part(conclusion) of the argument,it was clear that e is the only correct option.

We need to find a weakener in the argument.

From the Stimulus

1. Due to joint pain -> potential runners can't participate in running.
2. New treadmills (RGT)-> i) full benefits of weight loss (ii) no pain.

Pre-Thinking: Something which shows that the new treadmill's features can't result in either of the benefits that they're claiming - for example, reduced gravity causes no difference in pain ( or maybe even more ) OR full gravity is needed for weight loss OR treadmills aren't effective ( etc. )

A. Runners' preference has no relation to the effectiveness of RGT
B. Swimming may be better but we're discussing runners and their issues.
C. Contender: This could be a reason to not use RGT, but it doesn't say why RGT is ineffective for weight loss or pain reduction. ( muscle issues may not necessarily cause pain, also we're more concerned about joint pain)
D. RGT is not effective in some cases. So what?

E. Weight loss due to running happens because of long-distance running and carrying your own body weight. In reduced-gravity situations, that won't be possible ( or as effective ). Hence this answer choice is correct.

IMO E.

The marketer suggests using reduced gravity treadmills for people who want to achieve weight loss but have joint problems. But if losing weight requires carrying one's weight over distance, then reduced gravity treadmills may not be helpful in achieving the said goal. Hence, E.

(E) Much of the weight-loss benefit from running is derived from a runner having to carry his own body weight across a long distance.

Official Explanation

In any Strengthen or Weaken question, remember that the specificity of the conclusion is king. Here the details matter quite a bit in the conclusion, which is that those who suffer joint pain when running normally can, by using this treadmill, realize the full benefits of weight loss from running without the severe joint pain. Note that the strongest part of the conclusion is the "full weight loss benefits" - if those benefits are compromised at all by the treadmill, the conclusion is weakened.
Choice (E) does exactly that: if much of the weight-loss benefit of running comes from having to carry one's full body weight, then lessening that burden will lessen the weight-loss effect. (E) shows that this product will not likely achieve the lofty "full benefits of weight loss" standard set in the conclusion.
Among the other choices:

(A) misses the scope of who will be using the treadmill. Avid runners already run, so they are not the profile of people who are "unable to run due to joint pain." Their preference is then irrelevant to this study.

(B) also shifts the scope of the argument: even if swimming is better for weight loss, this argument is only about whether people can derive the same benefits from running on this treadmill that they would from running in general. Beware the always-popular "better plan" answer choice on many Weaken questions - just because a better plan exists (swimming) that does not mean that this particular plan (the treadmill) cannot accomplish its goal (achieving the same weight loss benefit as regular running).

(C) again misses the specific scope of the conclusion, which only addresses joint pain. Muscle and tendon strain introduces another type of potential injury, but the conclusion is specific that these people can achieve running benefit without joint pain in particular.

And (D) misses the specificity of "intense" joint pain in the conclusion. By saying that some people might experience some joint pain, (D) does not go far enough to show that people in general would experience intense joint pain.
