Aldolase is a protein found in the brain. In an experiment, subjects that consistently chose sweetened drinks when offered a choice between salty and sweetened drinks were found to have significantly higher concentrations of Aldolase in their brains than did subjects that consistently chose salty drinks over sweetened drinks. This observation strongly supports the conclusion that Aldolase causes subjects to crave sweetened drinks.

Which one of the following, if true, most supports the argument?


A. The craving for sweetened drinks does not invariably result in a subject’s choosing those drinks over salty drinks.
B. The brains of the subjects that consistently chose to drink sweetened drinks did not contain significantly more sugar than did the brains of subjects that consistently chose salty drinks.
C. The chemical components of Aldolase are present in both sweetened and salty drinks.
D. The subjects that preferred sweetened drinks had the higher concentrations of Aldolase in their brains before they were offered sweetened drinks.
E. Subjects that metabolize sugar less efficiently than do other subjects develop high concentrations of Aldolase in their brains.

Official Solution:


Aldolase is a protein found in the brain. In an experiment, subjects that consistently chose sweetened drinks when offered a choice between salty and sweetened drinks were found to have significantly higher concentrations of Aldolase in their brains than did subjects that consistently chose salty drinks over sweetened drinks. This observation strongly supports the conclusion that Aldolase causes subjects to crave sweetened drinks.

Which one of the following, if true, most supports the argument?


A. The craving for sweetened drinks does not invariably result in a subject’s choosing those drinks over salty drinks.
B. The brains of the subjects that consistently chose to drink sweetened drinks did not contain significantly more sugar than did the brains of subjects that consistently chose salty drinks.
C. The chemical components of Aldolase are present in both sweetened and salty drinks.
D. The subjects that preferred sweetened drinks had the higher concentrations of Aldolase in their brains before they were offered sweetened drinks.
E. Subjects that metabolize sugar less efficiently than do other subjects develop high concentrations of Aldolase in their brains.


This stimulus contains causal reasoning; the conclusion takes a correlation and turns it into a causal relationship. As with all causal arguments, once you identify the causality, you must immediately look to the question stem and then attack. In this instance, the author simply assumes that Aldolase is the cause. Why can’t the sweetened drinks lead to higher concentrations of Aldolase?
  1. The argument discusses the concentration of Aldolase in the brains of subjects; no mention is made of the sugar content of the brains of subjects. This answer, which focuses on the sugar content in the brains of subjects, therefore offers no support to the argument. Even though the brain might not contain more sugar, a subject could still consistently choose and drink drinks with higher sugar content.
  2. The argument discusses the concentration of Aldolase in the brains of subjects; no mention is made of the sugar content of the brains of subjects. This answer, which focuses on the sugar content in the brains of subjects, therefore offers no support to the argument. Even though the brain might not contain more sugar, a subject could still consistently choose and drink drinks with higher sugar content.
  3. The argument is that Aldolase in the brain causes subjects to crave sweetened drinks. The fact that Aldolase is in the drink does not help that assertion and may actually hurt the argument.
  4. Correct. The answer strengthens the argument by eliminating the possibility that the stated causal relationship is reversed - if the subjects had higher concentrations of Aldolase prior to taking the sweetened drinks, then the sweetened drinks cannot be the cause of the higher concentration of Aldolase.
  5. This answer choice is the opposite to what is asked in the question stem. This answer choice hurts the argument by suggesting that the causal relationship in the conclusion is reversed.

Answer: D

I think this question is poor and not helpful - the correct response is not coherent with its explanation.

I think explanation of this question is not correctly written for option A ( its same as B).

I can get why D is right but Can anyone explain why option A is wrong?

Option A states that its is not the craving that leads to choose Sugar over salt. Thus, supports that Aldolase is the cause and not any other factor,

Option A is incorrect because it says thet craving and choosing are not connected and even if a person chooses sweetened drinks he may actually crave for a salty one.
This option thus undermines the conclusion because it questions the conclusion that says "adolase makes people crave sweetened drinks".

I think this is a poor-quality question and I don't agree with the explanation. Pls explain why option a is wrong....
Pls clear whats wrong with Option A .as it says there could not be any other reason for conclusion to hold true..so only aldolase is the reason

Can someone help me with option E please? I think its supporting the conclusion perfectly. If you genereate less sugar, you need more to compensate it, so your body increases the level of A.. So this hormone stimulates someone to crave sweetened drinks.

why do they say this is reversed logic :D I know i am wrong i just dont get it :D

I think this is a poor-quality question and I don't agree with the explanation. Kindly look into this question. I think the options A and D have been interchanged. The answer explanation is also a proof.

Explanation for option choice A and option choice B is same. It appears that explanation for option choice B is also copied into explanation for option choice A by mistake.

I understand that in above question there are two option choices that strengthen the Causal Relationship. Here is my reasoning for the same.

Option choice C - The chemical components of Aldolase are present in both sweetened and salty drinks.
. What if aldolase is present only in sweetened drinks. That will lead to higher concentration of aldolase in the people who consumed sweetened drinks. In a way the causal relationship will be reversed that is sweetened drinks will lead to higher concentration of aldolase in the people. Information in option choice C eliminates this possibility by stating that aldolase is present in both drinks. Thus in a way strengthens the position that aldolase leads to the craving for sweetened drinks.


Option choice D - The subjects that preferred sweetened drinks had the higher concentrations of Aldolase in their brains before they were offered sweetened drinks.. As stated in the explanation - if the subjects had higher concentrations of Aldolase prior to taking the sweetened drinks, then the sweetened drinks cannot be the cause of the higher concentration of Aldolase.

Experts kindly comment.

Thanks
Sahil

I don't agree with the explanation. I understand the answer choice, but the explanation question by question of "why not" is poor-quality.
