A researcher finds that people who own more than two cars have bigger homes, more garage space, and make more money than people who own only one or two cars. Therefore, the researcher concludes that having more than two cars causes people to have homes with bigger garages.

B. alternate forms reliability.
C. alternative explanations.
D. temporal precedence.
