The Solution:

The survey of every third student that enters the library is biased.

The option that is likely to make the survey less biased is:

(option 2) The survey of every third student who enters the cafeteria.

Step-by-step explanation:

The students the enter the cafeteria are more representative of the whole students than those students that enter the library or others in the choiced options.

Thus, the correct answer is option 2.
