Question

lao needs current information for research. which detail from the selection helps analyze the usefulness for lao? a according to science america, what we experience as fear has to do with our brain and the animal instinct to survive. b the amygdala is responsible for communicating with the hypothalamus, a gland that floods the body with different chemicals. c every part of the body requires oxygen and blood in order to function, but the brain redirects blood flow in times of fear. d at the most basic level, our brains signal the body to produce adrenaline. this triggers a \fight or flight\ response in our bodies.

Explanation:

To determine which detail helps analyze fear's usefulness for survival, we evaluate each option:

• Option A: States fear is an animal instinct to survive, directly linking fear to survival utility, which is relevant for Lao's research on fear's usefulness.
• Option B: Describes amygdala - hypothalamus communication, focusing on brain - gland interaction, not fear's survival use.
• Option C: Discusses oxygen/blood flow in fear, about physiological processes, not survival usefulness.
• Option D: Explains adrenaline production in fear, about the "fight or flight" response mechanism, not the survival - related usefulness of fear.

Answer:

A. According to Science America, what we experience as fear has to do with our brain and the animal instinct to survive.
