Answer to Question 1

The first question will elicit greater support for cloning. The wording of the question appeals to the emotions of the respondent. The second question conjures up images of scientists experimenting on humans and cloned embryos, and will elicit less support. This is a form of response bias.

Answer to Question 2

B
