Farmers in Australia have begun spraying their wheat fields with wheat germ oil after planting seeds. Even though mice are attracted to the scent of wheat, which wheat germ oil emits, the farmers believe that, by spraying their fields with wheat germ oil, they will reduce the number of planted wheat seeds taken by mice.
Which of the following, if true, provides the strongest reason to believe that the farmers’ strategy will work?This is a Strengthen Plan question.
The plan is the following:
spraying their wheat fields with wheat germ oil after planting seeds The goal of the plan is the following:
reduce the number of planted wheat seeds taken by mice As is common in Plan questions, the passage does not provide a reason to believe the plan will work.
In fact, in this case, the passage presents a reason to wonder how the plan can work:
mice are attracted to the scent of wheat, which wheat germ oil emitsSo, the correct answer will provide support for the conclusion that the plan will work even though mice are attracted to the scent of wheat, which wheat germ oil emits.
(A) A by-product of the wheat milling process, wheat germ oil is relatively inexpensive.This choice provides support for the wrong conclusion.
It supports a conclusion along the lines of that the plan is practical in financial terms.
Since the fact that wheat germ oil is inexpensive doesn't mean that spraying fields with it will serve to reduce the number of seeds taken by mice, this choice doesn't do what we need.
Eliminate.
(B) Mice cannot get any significant nutrition from wheat germ oil sprayed on fields.The fact that mice cannot get significant nutrition from wheat germ oil doesn't indicate that spraying fields with it will prevent mice from taking wheat seeds to get nutrition.
Eliminate.
(C) The population of mice in Australia has increased to record size in recent years.If anything, what this choice mentions works against the success of the plan.
The fact that the population of mice has increased to record size is certainly not a reason to believe that a plan to reduce the number of seeds taken by mice will work.
Eliminate.
(D) Mice locate planted seeds to take from farmer’s fields by using their sense of smell.This choice is interesting.
After all, if mice locate planted seeds to take from farmer’s fields by using their sense of smell, then, if entire fields are sprayed with wheat germ oil, which emits the scent of wheat, mice may have trouble locating planted seeds. After all, in that case, not only the seeds but everything around them will smell like wheat.
So, this choice provides reason to believe that the plan will work.
Keep.
(E) Spraying wheat germ oil on newly planted fields does not negatively affect the growth of wheat plants.This choice supports the wrong conclusion.
It supports a conclusion along the lines of that spraying fields with wheat germ oil won't negatively affect crop production.
Since that fact that spraying fields with wheat germ oil does not negatively affect growth of plants does not mean that it will serve to reduce the number of seeds taken by mice, this choice doesn't do what we need.
Eliminate.
Correct answer: D
