Some scientists believe that sugar causes a specific type of pancreatic cancer. They have found that people who consume at least 2 carbonated drinks containing sugar per day have a 90% higher rate of pancreatic cancer than those who drink the same number of diet drinks per day. Therefore, if we were to substitute diet drinks for regular soda pop, it would considerably reduce our chances of getting pancreatic cancer.
Which of the following, if true, most seriously weakens the argument above.

a) Many diet drinks contain artificial sweeteners called cyclamates, which have been known to cause intestinal and bladder cancer in lab studies
b) Statistically, people who consume several sugared drinks a day are also the least likely to maintain a regular exercise regimen. It has been shown that regular exercise is a factor in reducing the pancreatic cancer.
c) People who generally avoid sugared beverages also tend to avoid sugar in other parts of diet.
d) Diet drinks have actually been linked to a higher risk of weight gain
e) The study showed that the increase in rate of pancreatic cancer remained the same whether the person drank 2 or 5 sugared drinks.

My doubts-

I know this is a classic cause - effect reasoning, however where I got confused is what we need to Weaken.
i.e whether we need to weaken is
sugar causes a specific type of pancreatic cancer -----equation A
or
Therefore, if we were to substitute diet drinks for regular soda pop, it would considerably reduce our chances of getting pancreatic cancer --- equation B

Correct answer choice is blatant enough. Need to understand that answer choice B is weakening equation A or B

Also, I need reasoning for choice C as why that is wrong.

Thanks

Edit: Corrected Option B.

Some scientists believe that sugar causes a specific type of pancreatic cancer. They have found that people who consume at least 2 carbonated drinks containing sugar per day have a 90% higher rate of pancreatic cancer than those who drink the same number of diet drinks per day. Therefore, if we were to substitute diet drinks for regular soda pop, it would considerably reduce our chances of getting pancreatic cancer.
Which of the following, if true, most seriously weakens the argument above.

Remember, in weaken questions, you have to weaken the conclusion which in this case states that by substituting diet drinks for regular soda pop, our chances of getting pancreatic cancer would considerably reduce.

Therefore we have to search for an answer choice that gives us reason to believe that regular soda pop is not a cause for pancreatic cancer.


a) Many diet drinks contain artificial sweeteners called cyclamates, which have been known to cause intestinal and bladder cancer in lab studies Ok.. so diet drinks cause other types of cancer. But this doesn't tell us anything about the effect of diet drinks relating to PANCREATIC CANCER which is what the conclusion of the argument clearly refers to. Therefore this does not weaken the conclusion in any way.
b) Statistically, people who consume several suggested (is this the same word used in the original question?)drinks a day are also the least likely to maintain a regular exercise regimen. It has been shown that regular exercise is a factor in reducing the pancreatic cancer.This provides us with with another reason as to why people who drink regular soda pop might be getting pancreatic cancer - Lack of exercise. Therefore since this alludes to the fact that lack of exercise and not soda pop is the reason they might be getting pancreatic cancer, this definitely weakens the conclusion.
c) People who generally avoid sugared beverages also tend to avoid sugar in other parts of diet. This makes no mention of whether these people get pancreatic cancer or not and therefore does not strengthen or weaken the conclusion
d) Diet drinks have actually been linked to a higher risk of weight gain We don't know the relation of weight gain to pancreatic cancer. Hence we cannot say whether this weakens the conclusion or not.
e) The study showed that the increase in rate of pancreatic cancer remained the same whether the person drank 2 or 5 sugared drinks. This, if anything, strengthens the argument by stating that irrespective of whether a person consumes 2 or 5 sugared drinks, there is definitely an increased risk of pancreatic cancer as a result of consuming sugared drinks.

One of the most important things in CR - you have to strengthen/weaken the conclusion of the stimulus. Just the conclusion.

So first thing to look for is the conclusion. It is pretty straight forward here, isn't it?
It starts with 'Therefore' and fits the description of conclusion perfectly. It is the conclusion of the stimulus then.

Focus on the conclusion: if we were to substitute diet drinks for regular soda pop, it would considerably reduce our chances of getting pancreatic cancer

What is it trying to tell you? It is saying that if you reduce your sugar intake, your chances of getting pancreatic cancer reduces.

I think the only confusion is between (B) and (C).
(B) is correct because it gives you an alternative cause of pancreatic cancer - no regular exercise. Since people who consume sugar drinks are also the ones who exercise little, the ones who consume diet drinks could be more active and hence, there could be an alternative explanation. Hence the conclusion that reduction in sugar will reduce your chances of getting pancreatic cancer is weakened.

(C) is a sneaky but incorrect option. It kind of strengthens the link between sugar and cancer, doesn't it? People who drink regular pop also consume more sugar in other things. So probably, people who consume diet drinks take less sugar in other things too and hence, their risk of cancer is lower. Don't forget the intent of the conclusion - it is establishing a relation between sugar and cancer, not between soda pop and cancer. The whole stimulus is based on the amount of sugar.

Thanks Karishma for the reply.

As you pointed out that we need to focus on Conclusion in Weaken /Strengthen question, however, I need to confirm one doubt. Can we state the conclusion in our own words as you did below(colored part). i.e. Are we allowed to state the logical intent of the conclusion, just as you found out in your reply?

While going through the explanation of this question from book, same conclusion is being derived i.e the one you found out logically and then options were analyzed in order to weaken it. That is where I got confused.

Please explain.
Thanks

Yes, you certainly have to focus on the intent of the conclusion. If one replaces sugar soda pop with diet soda pop but starts drinking fruit juices with added sugar, it doesn't help, does it?

That is how Verbal is different from Quant (though CR is closest to Quant). You take Quant on face value (if the variable given is 'a', it is 'a'. The author's intent cannot be 'b'.). In Verbal, you need to deduce the author's intent sometimes.

It has been shown that regular exercise is a factor in reducing the pancreatic cancer.

Does this mean that lack of regular exercise ---> increases the chances of cancer ???

Not simply a part of the pancreas, stomach or gallbladder are removed via the surgery treatment implemented in Whipple treatment for pancreatic cancer. Tumor concerning the pancreas may be tremendously helped with it. Usually, deficiency of information that's equally precise and simple to learn can easily weigh on already distressed individuals. This content can help patients, their own families as well as relatives to understand the Whipple procedure, survival rate, side effects and possible prospects.

Straight B.

One way to weaken the "To reduce pancreatic cancer, stop drinking sugared drinks" argument is to identify alternative causes of the disease. If exercise has been found to be a major reducer of the likelihood of the diseases, this revelation diminishes the need to cut down consumption of the sugared drinks.

Cheers,
Der alte Fritz.
