  A: Do you favor allowing doctors to use cloned cells in attempts to find cures for such terrible diseases as Alzheimer's, diabetes, and Parkinson's?
  B: Should research scientists be allowed to use cloned human embryos in their experiments?
 
  Which question do you expect will elicit greater support for cloning? Explain. What kind of bias is this?

Question 2

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
