Question

One Zydol capsule contains twice the pain reliever found in regular aspirin. A consumer will have to take two aspirin in order to get the relief provided by one Zydol. And since a bottle of Zydol costs the same as a bottle of regular aspirin, consumers can be expected to switch to Zydol.

Which of the following, if true, would most weaken the argument that consumers will be discontinuing the use of regular aspirin and switching to Zydol?

(A) A regular bottle of aspirin contains more than twice as many capsules as does a bottle of Zydol.

(B) The pain reliever in Zydol is essentially the same pain reliever found in regular aspirin.

(C) Some headache sufferers experience a brief period of dizziness shortly after taking Zydol but not after taking regular aspirin.

(D) Neither regular aspirin nor Zydol is as effective in the relief of serious pain as are drugs available only by prescription.

(E) A Zydol capsule is twice as large as the average aspirin.

MsInvBanker · Answer

I think it is C because,

A. Brings Aspirin and Zydol at par
B. Strengthens argument in favor of Zydol
C.  Weakens argument in favor of Zydol 
D. Does nothing to the argument
E. It is medicine, so size doesn't really matter

pkshankar · Answer

'C' and 'A' are both close. I initially picked C but now I think A is correct.
A says that a bottle of aspirin has at least twice as many capsules as does a bottle of zydol.
So a bottle of aspirin will be more effective than a bottle of zydol as 2 capsules of aspirin = 1 capsule of zydol.
C on the other hand says that some people suffer from headaches, here some could be 1 to all.
Hence C to me seems weak.

One Zydol capsule contains twice the pain reliever found in regular aspirin. A consumer will have to take two aspirin in order to get the relief provided by one Zydol. And since a bottle of Zydol costs the same as a bottle of regular aspirin, consumers can be expected to switch to Zydol.

Which of the following, if true, would most weaken the argument that consumers will be discontinuing the use of regular aspirin and switching to Zydol?

Given: 1 - one zydol capsule contains twice the composition found in aspirin.strength of one zydol capsule is equivalent to strength of two aspirin capsule. 
 2 - cost of a bottle of zydol and aspirin is same.
 3 - consumer will switch to zydol because zydol capsule is more effective per capsule, and cost of bottle containing the capsules is same .

weaken: what if the bottle containing aspirin capsules has more capsules than the bottle containing zydol capsules in the same cost. so there wouldn't be any benefit in terms of cost of capsules.

(A)  A regular bottle of aspirin contains more than twice as many capsules as does a bottle of Zydol.(Correct) 
 
(B)  The pain reliever in Zydol is essentially the same pain reliever found in regular aspirin. ( it doesn't help to weaken the argument)

(C)  Some headache sufferers experience a brief period of dizziness shortly after taking Zydol but not after taking regular aspirin.(Dizziness may be a side effect of zydol but this side effect may be due to double strength of zydol.it is possible that after taking two capsule of aspirin people may experience dizziness.

(D)  Neither regular aspirin nor Zydol is as effective in the relief of serious pain as are drugs available only by prescription.(doesn't weaken the argument)

(E)  A Zydol capsule is twice as large as the average aspirin.(size is irrelevant)

Choice A weakens the argument.

Thanks

Hea234ven · Answer

answer should be A. But, there are confusions between a and c. In C, it's said that SOME sufferers(NOT ALL) face dizziness after taking zydol. So, because only some sufferers have problems, we can't conclude that zydol is bad in general. These sufferers may have allergy on specific capsule.
Here we have to judge on the basis of cost saving. In a, as it's said that aspirin bottle has more than twice the capsule of zydol bottle (and price of two bottles are same), we can't actually save money by buying zydol bottle. The low quantity of zydol (1 zydol capsule equivalent to 2 aspirin) can be offset by including more number of aspirin capsule in the aspirin bottle.

Official Explanation

Step 1: Identify the Question Type

This is a Weaken question.

Step 2: Untangle the Stimulus

The conclusion is that consumers can be expected to switch to Zydol. The evidence is that although they have to take two aspirins to get the relief provided by one Zydol, a bottle of Zydol costs the same as a bottle of aspirin. There are two assumptions here - one is that Zydol really is the better value, while the other is that there are no unstated, factors that would make consumers not want to switch.

Step 3: Predict the Answer

A weakener will attack the author's assumption. Here, it will either suggest that Zydol is not as great a value as it appears, or that there is some other difference between the two medicines that would make consumers not switch to Zydol.

Step 4: Evaluate the Choices

(A)  shows that Zydol is not a better value after all. While the bottles cost the same, and consumers have to take twice as many aspirin to get the same amount of pain reliever, aspirin bottles contain more than twice as many pills in them. In the end, aspirin is actual cheaper per dosage. This makes it less likely consumers will stop taking aspirin and switch to Zydol, and therefore  (A) is correct.

(B)  doesn't make it less likely that consumers will switch to Zydol. The argument is about pain relief and which medicine is a better value. If the pain reliever is essentially the same, a potential difference between the pills is removed, and the issue of value becomes even more important.  (B)  doesn't address that issue.

(C)  points out something undesirable about Zydol, yet by itself doesn't make it less likely that consumers will switch to Zydol. The reason is that  (C)  doesn’t indicate whether these same headache sufferers experience a brief period of dizziness shortly after taking aspirin as well. More information is needed, so  (C)  cannot be said to weaken the argument.

(D)  brings up other drugs, which have no effect on the argument concerning just Zydol and aspirin.

(E)  is incorrect because there is no way of determining whether the size of the capsules is relevant. Perhaps consumers prefer the larger Zydol capsule size, perhaps they prefer the smaller aspirin size. It's impossible to determine from  (E) , so  (E)  cannot be said to weaken the argument.

TAKEAWAY:    With Weaken questions, keep the focus on the connection between the stated evidence and the conclusion - the assumption. Don't forget that the task is to attack that connection. That will make it easier to avoid wrong choices.

Answer: A

Hope it helps

KarishmaB · Answer

1 Zydol capsule = 2 aspirin tablets = 1 dose of pain relief

1 zydol bottle (with some x number of capsules) costs the same as 1 aspirin bottle with some y number of tablets.

Conclusion: People will switch to Zydol.

Well, they are likely to if the number of capsules in each bottle are the same because Zydol will have twice the number of doses for the same cost. Since you will need to take only 1 capsule of zydol (vs 2 tablets of aspirin), you will get more value out of zydol bottle. 
Both will provide equal value if Zydol bottle has say 50 capsules and Aspirin bottle has 100 tablets. Both will provide 50 doses of pain relief for the same money.
But what if Zydol bottle has 50 capsules but Aspirin bottle has 200 tablets? Now for the same money Zydol gives 50 doses but aspirin gives 100 doses. So people will prefer aspirin only.

Option (A) says that aspirin has more than twice as many capsules as does Zydol. So if Zydol has 50, aspirin has more than 100 so it does provide more value. This means people will not switch to Zydol.

Answer (A)

k24Moriarty · Answer

Please explain why C cannot weaken the argument.

MartyTargetTestPrep · Answer

(C) does weaken the argument a little. (A) seriously weaken the support provided by the evidence.

It's not ideal that (C) weakens the argument, but (A) is a better choice. So, there is a path to getting this less than ideal question correct.

Mayankcadbury · Answer

Option A directly attacks the premise which is providing support to the argument. This argument focuses a lot on cost of medicine from beginning. Option C talks about qualitative aspect of both the medicines for which argument is not bothered about.Therefore option A is best suited to attack the argument

cigarboy · Answer

Argument is all about the number of pills and cost.

Option A: regular bottle of aspirin contains more than twice as many capsules as does a bottle of Zydol - Weakens the argument most.
