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.
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)
