Question

Max is administering a polygraph test to a suspect in a murder investigation. Before he asks the suspect about the murder, Max asks him a series of easy questions, such as "Is your name X?" and "Do you live at X address?" Max notes the suspect's heart rate and respiratory rate as he answers these questions. What is the purpose of asking these questions?

A) To establish the suspect's identity.
B) To increase the suspect's anxiety.
C) To monitor physiological responses.
D) To test the suspect's memory recall.

Answer 1

The purpose of asking easy questions before asking about the murder is to monitor physiological responses.

Step-by-step explanation:

The purpose of asking these easy questions before asking the suspect about the murder is to monitor physiological responses. By noting the suspect's heart rate and respiratory rate as he answers these questions, Max can observe any signs of physiological arousal, such as increased heart rate, respiration rate, and sweating, which may indicate potential deception or concealment on the suspect's part.
