Complete Question Explanation

Cannot Be True. The correct answer choice is (B)

In this stimulus we are told of the effects of sugared drinks on athletes. Their sweetness makes athletes more likely to drink them, avoiding dehydration, and in small doses sugar can enhance the hydration and forestall fatigue by maintaining glucose levels. While there are these benefits, there are potential hazards as well: large amounts of sugared beverages can draw water from the stomach, worsening dehydration.

The question stem tells us that all of the answer choices could be true except for one. Thus, among the answer choices we will see four wrong answers all of which are possible given the facts of the stimulus, and the one correct answer, which cannot be true.

Answer choice (A): The stimulus certainly allows for this possibility; glucose is the only sugar discussed, but there could be others.

Answer choice (B): This is the correct answer choice. It cannot be true that fatigue-fighting substances always worsen dehydration, because small amounts of sugar both fight fatigue and enhance hydration.

Answer choice (C): We are told that athletes like sugared beverages, but once they are dehydrated, as this choice specifies, their tastes could quickly change.

Answer choice (D): Fatigue and dehydration are distinct physiological problems, and they could have distinct factors lead to their respective exacerbations.

Answer choice (E): The stimulus discusses the effects of sugared beverages, but this still allows for the primary factor to be blood-water level.

Hi,

I apologize if this should be clear, but what exactly is (E) saying? And how does it relate to the stimulus? Thank you, I appreciate the help.

Choice (E) is telling us that there is a definite relationship between water absorption rates and the amount of water present in blood. This would tell us that one person with 90% water in their blood would have a faster or slower absorption rate than someone with 95% water in their blood.

The word "primarily" tells us that the amount of water already in blood is the most important factor in rate of absorption. Since the stimulus did not make claims about sugar being the most or only factor in water absorption, knowing that there is another more important factor is possible. Since this can be true, it is not the correct answer.

Hi, I just have a question for (B).

Can't there be other substances that "delay muscle fatigue when consumed"? Electrolytes, for instance, may fit into this category, thereby allowing (B) to no longer be limited to the discourse on "sugared beverages". If this be the case, then (B) could still be true despite what is said in the stimulus rendering it no longer a MBF answer choice.

Hi sureniti2024!

A problem with answer choice (B) is the language "invariably." The answer choice is saying that if substances that delay muscle fatigue are consumed, this "invariably" exacerbates problems caused by dehydration.

This must be false, because we're told in the stimulus that (1) "small amounts of sugar ... delay muscle fatigue," and (2) some amount of sugar in drinks "can be helpful in avoiding dehydration." So (small amounts of) sugar is an example of a substance that delays muscle fatigue but does not invariably exacerbate problems caused by dehydration.
