Question

students know that a room common to them and their science lab will be bugged next year. the students want to know if the temperature in the room will be higher next year. how could students test if the bugging affects the reality of the supposed?
a. they can collect grubs living in the stream near the science lab to a problem.
b. they can do an internet search for the effects of bugging on the health of organisms.
c. they can compare measurements of daily temperature and humidity from this year to next year.
d. they can make a questionnaire and ask people if the use of bugging will be healthy or not.

Explanation:

To test if the bugging (assuming it's about some intervention like bugging a room for a purpose, maybe related to temperature or another factor) affects the outcome, comparing measurements (like temperature) before and after the bugging (intervention) is a valid experimental approach. Option C suggests comparing measurements of a variable (e.g., temperature) before and after the supposed bugging, which is a direct way to test the effect. Option A is about collecting opinions which is subjective, B is about internet research on effects (not testing the specific situation), and D is about a questionnaire on comfort which is also subjective. So C is the best way to test the reality of the supposed effect.

Answer:

C. They can compare measurements of key temperatures and humidity from outside the bugged room.
