Critical Reasoning

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
plywood boxes
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

Probably the easiest question that I have seen in a long time.

(A)

Agree - A

I also think it to be A

whats the OA?

IMO A.

OA is A

A 4sure,,,

picked A.

I marked D!

I am not getting why A is correct? - it does not tell anything about the dissipation time of eight hours!

I am confused here. Please help me with this question.

Thanks

I'd say A but I'm afraid more because of my intuition than any logic.

I will Go with option A in this case.
