Quote:
A certain apple orchard typically has a large yield mid-season, while the number of apples decreases near the end of the season. The apples picked early in the season are larger and brighter, and those picked late in the season are smaller and duller. A pie maker who uses the orchard's apples claims that her profits will increase near the end of this year's season.
Which of the following would be most useful in evaluating the pie maker's claim?
(A) comparing this year's predicted profits to last year's profits.
(B) calculating the number of apples needed to make each pie.
(C) determining whether smaller, duller apples make better-tasting pies.
(D) comparing this season's pie quality to last season's pie quality.
(E) determining whether the characteristics of the apples affect the price of pies.
The right answer here is
E, but option C is a tempting trap! The first thing to note with this question is that it's asking us to evaluate the argument. This means that we have a conclusion, but we don't know whether this conclusion is a sound one or not. It is our job to find a statement that can tell us whether this conclusion works or not. Hence, the option we're looking for should, depending on how we answer the statement, lead us to both possibilities (conclusion good/conclusion bad).
A - This comparison does nothing to help us evaluate the conclusion that "apple pie profits will increase toward the end of the season". It makes no difference whether these predictions are higher than last year's outcome or not, so this option is irrelevant.
OUTB - This may appear tempting at first but in reality answers nothing new. If the number of apples needed is very high (since they are smaller) it still doesn't tell us anything about profits, since there are so many other unanswered factors, such as the cost of said apples or the price of a pie.
OUTC -
This is a trap! On the outset, it may seem like this is relevant, because if the pies taste better, profits should increase, and if they taste worse, then profits should decrease. One problem though: this requires the further assumption that better tasting pies would lead to more profits. We don't know if buyers would pay more, or if this would affect the price of the pie in any way.
OUTD - This option is incorrect for the same reason that A is incorrect, it makes no difference if the pies taste better because the conclusion is about profits, not taste.
OUTE - By elimination, this option must be correct. But let's confirm. If the characteristics of apples do affect the price of pies, it will ensure better profits end the end of the season,
making the conclusion more valid. If not, we can't say that the profits will improve at the end,
making the conclusion less valid. Hence, this option allows us to clearly evaluate whether the conclusion is good or not and is therefore
CORRECT.
As with any question that deals with assumptions, it is essential that you correctly ID the conclusion, so as not to be led down the wrong path.
