Answer 1

In the context of collecting data, it is most reasonable to use the entire population instead of a sample when you have direct access to the complete group you are interested in.

Among the options given, the situation where it is reasonable to use the entire population is:

**A teacher wants to know his students’ favorite holiday in all of his math classes.**

This is appropriate because the teacher can easily survey all his students (the entire population) in his math classes without needing to use a sample.

The other scenarios involve larger populations or situations where a sample would be more practical or necessary for analysis.
