OG – 13. Q # 59Which of the following most logically completes the passage?
A recent government study links the high rates of respiratory ailments in Groverston to airborne pollutants released by the Woodco plywood manufacturing plant there. To address the problem the government imposed strict regulations on emissions which will go into effect in four years. Although Woodco plans to cut its emissions in half two years ahead of schedule, it is unlikely that the rate of respiratory ailments will decline before the regulations go into effect, since _______.
A.the number of facilities capable of treating respiratory ailments is not likely to increase
B.reducing emissions even further than planned would necessitate decreasing production at Woodco
C. it is difficult to make accurate, long-term predictions about emissions
D.not all respiratory ailments are caused by airborne pollutants
E.three new plywood manufacturing plants are about to go into production in Groverston
OA:
EWhy is D not the valid answer? There can be other factors as well which leads to respiratory ailments and these factors will only decline after the government regulations go into effect.
Pls help clarify this doubt. I was very confident of Option ‘D’. Was actually surprised to see that this is not the OA
OG – 13, Q # 65Which of the following logically completes the passage?
Pecan growers get a high price for their crop when pecans are comparatively scarce, but the prices drops sharply when pecans are abundant.
Thus, in high yield years, growers often hold back part of their crop in refrigerated warehouses for one or two years, hoping for higher prices in future.This year's pecan crop was the smallest in five years. It is nonetheless quite possible that a portion of this year's crop will be held back,since
A) Each of the last two years produced record breaking pecan yields
B) The Quality of this year's pecan crop is no more worse than the quality of the pecan crops of the previous five years
C) pecan prices have not been to sharp fluctuation in recent years
D) For some pecan growers , this year's crop was no smaller than last year's.
E) the practice of olding back part one year's crop had not yet become widespread the last time the pecan crop was as small as it was this year.
OA:
AWhy is ‘E’ wrong?
Option E states that the practice of holding back the crops had not become widespread which means that the crops were sold which means that the pecan growers had no inventory.
Furthermore, the quantity was the same. Hence they will hold back the crops this year in order to gain more profits in future
OG – 13 . Q # 67Several industries have recently switched at least partly from older technologies powered by fossil fuels to new technologies powered by electricity. It is thus evident that less fossil fuel is being used as a result of the operations of these industries than would have been used if these industries had retained their older technologies.
Which of the following, if true, most strengthens the argument above?
(A) Many of the industries that have switched at least partly to the new technologies have increased their output.
(B) Less fossil fuel was used to manufacture the machinery employed in the new technologies than was originally used to manufacture the machinery employed in the older technologies.
(C) More electricity is used by those industries that have switched at least partly to the new technologies than by those industries that have not switched.
(D) Some of the industries that have switched at least partly to the new technologies still use primarily technologies that are powered by fossil fuels.
(E) The amount of fossil fuel used to generate the electricity needed to power the new technologies is less than the amount that would have been used to power the older technologies.
OA:
EMy answer : C
But the
OG does not provide a clear explanation even though they have mentioned that this is what most would expect. Even the right answer has no explanation.
‘E’ states that the amount of fossil fuels used is less in new technologies as compared to older technologies. This strengthens the argument no doubt.
But As per ‘C’ , since more electricity is used , obviously less fossil fuel is being used --> Isn't this stronger than Option ‘E’
Pls clarify . Thanks
