Because people who exhibit mania have very elevated moods, a new test for mania includes questions about how happy a person feels and how often he or she laughs. This test has:

A) high face validity.
B) low face validity.
C) no face validity.
D) masked face validity.

High face validity means that the test appears to measure what it is supposed to measure. In this case, since mania involves elevated moods, questions about happiness and laughter directly relate to the condition being tested for, making the test's purpose clear and relevant.
