Well guys, first time trying to help another fellow students here. I am hoping to do it well
.
I would say that this is one small text, so you guys should not spend more than 15 minutes in reading + answering.
So, let's go for the questions:
Quote:
1. Which of the following statements best sums up the purpose of McKillop’s experiment?
A. He contrasted several methods for establishing more credible methods for controlling rabbit populations.
B. He set out to express the damage inflicted by rabbits on farmers' crops in a more tangible, monetary sense.
C. He endeavored to prove that rabbits are more destructive than most people perceive them to be.
D. He hoped to determine the crop for which rabbits showed the most ardent appetite.
E. He wanted to portray the rabbit in a less flattering manner.
A.
We see in the end of the passage:
"Farmers may now be able to attach a dollar value to the crops that rabbits feed on, but they still lack the most important piece of information that Dr- McKiIlop's study did not reveal: how to stop them."
So, A is out.
B.
In the entire passage the author show to us this. Let's keep it for now.
C.
We can see that Gordon McKillop only appear after the author convince us that the rabbits can be a real problem. So, the study is not for showing this.
C is out.
D.
This one can confuse us a little.
See in the passage:
"just finished a study that monitored the appetites of rabbits let loose to graze on several crops. As a result, farmers can gauge rabbit damage more effectively, allowing them to anticipate the
mom (money) they will lose and make necessary compensation. "
But, after reading the whole passage is clear that he is talking about the costs, not the kind of crop.
E.
Well, I am not able to show how much this is wrong. Hopefully this is obvious for all of you.
Quote:
2. The passage supplies information about each of the following EXCEPT
A. the population density of rabbits
B. the best way to prevent rabbits from decimating a certain crop
C. the duration of McKiIlop’s study
D. the rate at which rabbits normally reproduce
E. the amount of grass usually grown annually upon a hectare of land
In this question I will go straight for the answer:
B.
Why?
"Farmers may now be able to attach a dollar value to the crops that rabbits feed on, but they still lack the most important piece of information that
Dr- McKiIlop's study did not reveal: how to stop them. "
I admit that while I was answering this one, I didn't find the another answers (please GMAT Ninja, forgive me for that. I know that I have to find 4 wrong answers). But, the text is really clear on this one. So, let's skip. (If you guys want, I can after show in the passage each one of the others.)
Quote:
3. Each of the following can be inferred from the passage EXCEPT
A. in the agricultural marketplace, barley is at least twice as expensive as grass
B. at one point. myxomatosis and viral hemorrhagic fever were more effective than they are now
C. the power wielded by a certain type of farmer is at least partly influenced by financial impact of that farmer's product
D. the cost incurred by farmers to rid themselves of large rabbit populations far exceeds the monetary damage done to the farmers' crops
E. rabbits are unable to tunnel through the ground at a depth that is greater than ten feet
A.
"This translates to more than $3 worth of damage per rabbit per year-a seemingly nominal sum until one considers that most grasslands are home to as many as forty rabbits per acre. The rabbits‘ taste for barley was about the same as that for grass in terms of percentage.but the cost was calculated to be almost $7 per rabbit. "
A is out.
B.
"most rabbits have developed resistance to viral diseases such as myxomatosis and viral hemorrhagic fever that have been introduced to curb reproduction."
B is out.
C.
Well, this one actually I couldn't find directly in any single part of the passage, because anywhere is talking about "power wielded by a farmer". But we can kind of admit it, it makes sense.
Let's hold it for one second.
D.
"Shooting and trapping rabbits is too time-consuming and inefficient".
This is what we were searching for. In this part of the passage, the author do not say anything about the cost.
D is much better than C.
E.
"To keep numbers constant, each enclosure was surrounded by fence that was entrenched ten feet into the ground"
E is out.
Quote:
4. Which of the following hypothetical situations best exemplifies a potential problem that would most seriously undermine the merit of McKillop’s study?
A. Several rabbits develop a new strain of myxomatosis that renders each completely sterile.
B. Due to a decrease in supply, the price of barley suddenly doubles.
C. It is determined that younger, more energetic rabbits consume almost double the food that an older rabbit does.
D. A rare drought inhibits plant growth in the enclosures for several months.
E. Soon after the experiment begins, a predatory animal finds its way into some of the rabbit enclosures.
In this question we are looking for the same reason that we have in "Weaken" questions in CR.
A. In the study the rabbits were of the same sex. So, the possibility that they were sterile is not a problem.
B. The price of any product rise wouldn't undermine the merit of the study. Here we are searching for things that would prevent the rabbit to eat the determined quantity.
C. Well, the author got me in this one. Just after saying that we need to search for quantities he put this answer. Well, it'is wrong just because this not interfere in the total quantity eaten for the total rabbits. Doesn't matter if some rabbits eat more or less. It matters the total eaten.
D. This one is easy to took off. It is saying nothing about rabbits.
E. A predatory animal would kill some rabbits, putting the quantity calculated into question. This is our answer
Quote:
5. in the last paragraph, the author is primarily concerned with
A. exposing a problem to which McKillop‘s study has failed to supply a solution
B. suggesting that rabbit farmers and chicken farmers are often at odds when it comes to agricultural legislation
C. citing evidence that McKiIIop’s study is woefully incomplete
D. comparing the various methods that farmers have used in order to keep rabbit populations under control
E. establishing that foxes have an equal appetite for rabbits as they do for chickens.
Finally the last question. I was getting tired of typing.
In this question we need to understand the last paragraph as a whole.
A. Well, it looks really nice to me. So, let's keep it.
B. The paragraph don't say nothing about agricultural legislation.
B is out.
C. I was really tempted to choose this one. Why I didn't?
2 motives:
1) It doesn't show any evidence. It points to us a problem, not a evidence.
2) It doesn't say anywhere that the study was unfinished.
C is out.
D. The paragraph show to us that the study failed to present any good method.
D is out.
E. The easier in this question. This is the last important thing in the paragraph.
I hope that you guys liked my answers. If not, please comment this post showing which parts I got wrong.
Thanks for reading until here
