When a person speaks,brain waves and bloodflow are especially likely to reveal increased activity in the

A) hypothalamus.
B) left hemisphere.
C) amygdala.
D) right hemisphere.

The left hemisphere of the brain is typically associated with language production and comprehension, so increased activity in this area would be likely when a person is speaking. The hypothalamus and amygdala are more involved in emotional responses and regulation, and may not necessarily show increased activity during speech unless it is emotionally charged. The right hemisphere is typically associated with spatial processing and may not be as directly involved in language production.
