Regulations will not allow a pesticide that is toxic to humans to be used inside houses
unless the pesticide will dissipate completely from the air within eight hours after its
application. One test that pesticide manufacturers standardly use to determine how
quickly anti-termite pesticides dissipate involves spraying the pesticides on the walls of
room-sized plywood boxes and then timing its dissipation.
Which of the following would it be most useful to know in order to evaluate whether a
dissipation time of just under eight hours on the manufacturers’ test indicates that an antitermite
pesticide that is toxic to humans obeys regulations for use in houses?
A. Whether anti-termite pesticides dissipate more slowly in furnished rooms than in
B. Whether people who apply anti-termite pesticide standardly wear protective
equipment that prevents them from being exposed to the pesticide
C. Whether people whose house is being treated with anti-termite pesticide generally
know that they should remain out of their house during the hours immediately after the pesticide’s application
D. Whether there are anti-termite pesticides that are toxic to humans that, when
subjected to the manufacturers’ test, dissipate completely from the air in the boxes
in well under eight hours
E. Whether anti-termite pesticides that are not toxic to humans tend to take longer to
dissipate than those that are toxic.
Thank God i got it correct this time. It is Option A.
Assumption question type and Evaluate question type have one thing in common i.e. an implied premise or a bridge between premise and conclusion.
In this question, Option A forms a bridge between the Most Important Premise and the conclusion. Lets evaluate all the options thoroughly:-
Option B:- Out of scope - as for the anti-termite pesticides that are toxic to humans to pass the test, there is no mention that the people should be wearing any
Option C:- Out of scope - People awareness is also not a part of the premise. The litmus test is whether the pesticide dissipates before 8 hrs of application.
Option D:- Out of Scope - Regulators do not care if there are no such pesticides that exist in the market or no. Even if they do not exist, it is not their business.
Option E:- Out of Scope - The argument does not talk about the pesticides that are not toxic to humans. We are only concerned with the pesticides that are toxic to
Option A:- This is exactly our concern and hence the right answer choice - The most important premise states that the regulators test the pesticide on 4 sided plywood walls, then will it be similar to the houses i.e. <= 8 hrs where pesticides shall be applied. If yes, then argument falls apart, if no then argument holds.
Hence, Option A is the correct answer.
Hope the above helps!!!
