PrepTest 90+, Section 4, Question 14
Psychologist: Most people's blood pressure rises when they talk. But extroverted people experience milder surges when they speak than do introverted people, for whom speaking is more stressful. This suggests that the increases result from the psychological stress of communicating rather than from the physical exertion of speech production.

Which one of the following, if true, most strengthens the psychologist's argument?
Medications designed to lower blood pressure do not keep the people who take them from experiencing blood-pressure fluctuations when speaking.
In general, the lower one's typical blood pressure, the more one's blood pressure will increase under stress.
Introverted people who do not have chronically high blood pressure often sense the rises in blood pressure that occur when they speak in conversation.
Deaf people experience increased blood pressure when they sign, but no change when they move their hands for other reasons.
Extroverted people are more likely to have chronically high blood pressure than are introverted people and are more likely to take medication to lower their blood pressure.
