a person is hired to be a pilot because they are a good driver.
to test for memory, participants were asked to recall a list of words previously read to them.

Explanation:

Internal validity refers to whether a test or study measures what it claims to measure. The first option uses a quiz about an unrelated war (Civil War) to assess knowledge of the Revolutionary War, which fails to measure the intended construct, creating an internal validity issue. The other options relate to inappropriate inferences about skills, but the first directly involves a measurement tool that does not match the variable it is supposed to assess.

Answer:

A. A quiz on the Civil War is used to determine knowledge of the Revolutionary War.
