Answer 2

It is a biased question.

Explanation:

You are surveying students to find out if they prefer anchovies or vegetables on pizza.

Do you prefer slimy anchovies or fresh vegetables on your pizza?

This question is biased. Firstly, there are two different adjectives used like slimy and fresh and slimy cannot be anyone's choice for sure. If both were fresh, then it would be unbiased.
