Answer to Question 1

B
A group refers to a cell, or combination of treatment levels. The participants in a group do not actually meet, but are tested individually.

Answer to Question 2

D
Demand characteristics occur when participants know what the experiment is about. One way to reduce demand characteristics is to disguise the purpose of the experiment; for example, by using a cover story.
