   8. To test a hypothesis about a given variable, experimental and control groups are tested in parallel. Which of the following best explains the dual experiments?
   9. A) In the experimental group, a chosen variable is altered in a known way. In the control group, that chosen variable is not altered so a comparison can be made.
   10. B) In the control group, a chosen variable is altered in a known way. In the experimental group, that chosen variable is not altered so a comparison can be made.
