Because of a recent drought in Florida during the orange-growing season, the price of oranges this season will be three times the usual price. This will drive up the cost of producing orange juice and thus push up the price of orange juice for the consumer.
Which of the following, if true, most seriously weakens the argument above?The argument assumes that a drought in Florida will make oranges much more expensive and that this will therefore raise the consumer price of orange juice. The best weakener is the one that shows Florida is not the only relevant source of oranges, so a Florida drought may not strongly affect orange juice prices overall.
(A) The recent drought was not as severe as scientists predicted.
This weakens the argument somewhat, but it does not directly show that orange prices or juice prices will not rise sharply.
(B) States other than Florida also supply oranges to orange juice manufacturers.
This is the best answer. If orange juice manufacturers can also get oranges from other states, then a drought in Florida may have much less effect on the overall cost of oranges used in juice production. That directly weakens the conclusion.
(C) Other ingredients are used in the production of orange juice.
This is too weak. Even if other ingredients are used, oranges could still be the main cost.
(D) Last year the price of oranges was actually lower than the average price over the past ten years.
This is irrelevant. The argument is about this season’s drought and this season’s prices.
(E) The price of oranges will eventually be $0.48 per crate.
This gives a number with no useful comparison, so it does not help evaluate the argument.
Answer: (B)
