Davison River farmers are currently deciding between planting winter wheat this fall or spring wheat next spring. Winter wheat and spring wheat are usually about equally profi table. Because of new government restrictions on the use of Davison River water for irrigation, per acre yields for winter wheat, though not for spring wheat, would be much lower than average. Therefore, planting spring wheat will be more profi table than planting winter wheat, since___________. (A) the smaller-than-average size of a winter wheat harvest this year would not be compensated for by higher winter wheat prices (B) new crops of spring wheat must be planted earlier than the time at which standing crops of winter wheat are ready to be harvested (C) the spring wheat that farmers in the Davison River region plant is well adapted to the soil of the region (D) spring wheat has uses that are different from those of winter wheat (E) planting spring wheat is more profi table than planting certain other crops, such as rye OA is A. I've got two questions. 1. What type of question should we put this question into ?? I feel confused about this question because I do not know what does the 'since___________' mean?? I mean I don't know whether I should do.. Should I find a statement that support the argument, or explain the reasoning of the argument, or the assumption of this argument? I confuse. 2. Why is C wrong? I think C helps explain the argument and rule out the possibility that spring wheat cannot survive in this region. So why is C wrong? Hope anyone can help me!! Thanks!

Here the conclusion is "Therefore, planting spring wheat will be more profitable than planting winter wheat, since" the main word is profitable. 9 out of 10 times answer choice that attacks this word (or you may call it a scope of the argument) must be the correct answer, saying this you should still read all the other answer choices and eliminate them. So here A and E are the answer choices that consider profitably but remember the arguments says the decision is between winter wheat and spring wheat, so E is out of scope.Hence answer is A. OA is A. I've got two questions. 1. What type of question should we put this question into ?? I feel confused about this question because I do not know what does the 'since___________' mean??

Hi, selango. But I think this article has already told us per acre yields for winter wheat, though not for spring wheat, would be much lower than average. Thus, if per acre yields for winter wheat are much lower than average, and per acre yields for spring wheat keep the same, then the planting Spring wheat will be more profitable, because they are equally profitable per acre yields. Hence I think A and C are both right because they both rule out the possibility that winter wheat will be more profitable than spring wheat under the condition that per acre yields for winter wheat would be lower than spring wheat. Hope more replies.

The argument also concludes that spring wheat will be more profitable than winter wheat. Given this evidence you must ask yourself, if these two wheats are normally equally profitable, why would the lower than average yield of winter wheat per acre make it less profitable than spring wheat? There is only one conceivable instance where less yield per acre of winter wheat will become equal or more profitable than the average spring wheat yield. If the winter wheat becomes more expensive, you might be able to conclude it is equally profitable or more profitable. If the price stays the same or decreases, then the profitability of winter wheat will decrease, because your making less money per acre beacuse there is less wheat. C is wrong because it doesn't tell us anything about the price, cost, or, therefore, the profitability of either plant. B and D are wrong for similar reasons. E is wrong because it compares the profitability of spring wheat to other crops which is irrelevant. A is correct. I hope this helps. Please let me know if you would like me to clarify my points.

Hi sk818020! Thanks for your reply. But I still think C is an correct answer IF this is an assumption question. Because if the farmers cannot plant the wheat, or if they cannot yield the plant, how can they make profits and how can spring wheat more profitable than winter wheat? Because spring wheat cannot even plant on this soil ! However, as David says, this is a support question, hence C here is incorrect. Thanks anyway, I know more about support and assumption questions from this post.

Hi! David! If this question is an assumption question, is A still correct?

rx_11 -

To answer your question, I would not treat this as an assumption just because it is asking for a premise that is not yet stated. All strengthen questions are looking for a premise that has not been stated. On official questions the word "assumption" or "assumes" will be there. However, if you do treat this as an assumption A is still the best answer.

sk818020 (Jared) has given a great explanation on answer choice A and that is why I commented on other aspects of the problem - no need for me to duplicate.

The argument already tells you that Spring wheat and Winter wheat are usually equally profitable. So as Selango says, the two wheats should each be fairly well adapted to the soil - or else they are both poorly adapted. In either case I do not think that C is an assumption. What if the wheat is not well adapted? What if it is only "okay" in terms of adaptation? What if the adaptation is average? That would not mean that Spring wheat will not be more profitable given what we are already told. The thing that has changed is that winter wheat yields are down. So this will result in less profit unless the price is up. As Jared says, as long as answer choice A is in place this means that spring wheat will be more profitable. The only way to make winter wheat more profitable is for winter wheat to command higher prices. Choice A eliminates this possibility.

So strengthen or assumption A is the correct answer.

Hi David,
this is from OG-12 Q 47.
I treated this as an assumption question as we need to find an additional premise(Since,......).

With my little stopwatch timer running, I spotted a gap in the arguement -"per acre yields for winter wheat, though not for spring wheat, would be much lower than average.". So I went like this - " We need to find an answer choice that would justify this ".

so I used C to fill in this GAP. -"all right the spring wheat is well adapted so it will give higher yields"

When I went back to review I realized the answer is A. After reading the explanations and applying the negation I am quite convinced that A is right. Still isn't C too close for comfort ?

Please let me now where my reasoning went wrong.

(Edit : I think I realize what I messed up. I made an additional assumption that higher yields = more profits)

The answer needs to address this year's differential between spring wheat and winter wheat because normally they are equally profitable. C tells us nothing about winter wheat. The only thing we might say is that it tells us that winter wheat is well-adapted since spring and winter wheat normally are equally profitable therefore presumably equally well-adapted.

Try the denial test. If the lower winter wheat yield WOULD be compensated for by higher prices, then we would not know whether to plant winter or spring wheat. Since denying A leaves us without evidence that spring would be more profitable, it kills the argument.
