Explanation:

Spraying the pesticides on plywood boxes seems a better alternative as this method is used to check the time it takes for the pesticide to dissipate.

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 anti-termite 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

A. Whether anti-termite pesticides dissipate more slowly in furnished rooms than in  plywood boxes.

Explanation:

The fact that the test was done in box sized room and timed and  not in the actual room is a  comparative clue, because  the  time of dissipation  of the pesticides on the walls of the room size board should    be an indicator  to determine if the pesticide will be applicable to actual sized room or not.

Assuming the dissipation   time  on  the walls of  room size box  is less than 8 hrs then it is  applicable to be used in actual room. However if  it lasts longer  than 8 hrs,then it will have a toxic effects on the wall of the actual room, and therefore  not applicable.

Therefore in option A, : Whether anti-termite pesticides dissipate more slowly in furnished rooms than in plywood boxes   if the pesticides dissipation time on the walls of  room -sized board is less than 8 hrs, then for it to be used in the actual room the dissipation time should  also be lesser or 8 hrs in the actual room walls. However if the time to dissipate is greater than 8 hrs then it is not applicable therefore A is the best option .
