Question

question 3 of 5
what discovery does the narrator in \exhalation\ make by dissecting his own brain?

a. physical pain derives from the brain.

b. brain activity slows due to low air pressure.

c. lung function is inhibited by lower oil content.

d. sight and body movement are intricately connected.

Explanation:

In Ted Chiang's "Exhalation," the narrator (a mechanical being) dissects his brain and discovers that brain activity depends on air pressure. As the world's air pressure equalizes over time, brain activity (and thus perception of time) slows, which is the key discovery from the dissection. The other options do not align with the story's plot points.

Answer:

B. Brain activity slows due to low air pressure.
