Question

Mr. Hanson is strongly suspected of embezzling money from his employer. He has denied the allegation. To determine whether he is lying, investigators are most likely to ask Mr. Hanson to take a(n) ________ test.
a. electrocardiograph.
b. polygraph.
c. myograph.
d. tomograph.

Answer 1

Answer: b. polygraph

Explanation:

A Polygraph test is used to record various bodily responses which when interpreted can be used to test if a person is lying. Things such as pulse, respiration, blood pressure and skin conductivity are tested while a person is asked a series of questions. The basic premise is that the body reacts to questions in a different way when telling the truth as opposed to when telling a lie.
