The author explains the "fight or flight" response by comparing and contrasting

A) humans to tigers
B) workers to bosses
C) modern man to cavemen
D) adrenaline to heart failure

I thinking d or b.

The author of what?

The correct answer is C) modern man to cavemen. The author explains the "fight or flight" response by comparing and contrasting how it was beneficial for cavemen (who had to quickly respond to physical threats in their environment) and how it is still relevant in modern times (as humans still experience stress and danger, although in different forms).

To determine the correct answer, let's break down the question and assess the options:

A) Humans to tigers: This option suggests a comparison between different species and their respective "fight or flight" responses. While there may be some similarities, this comparison is not explicitly mentioned in the question.

B) Workers to bosses: This option involves a relationship between different roles in a workplace but does not directly relate to the "fight or flight" response mentioned in the question.

C) Modern man to cavemen: This option highlights a comparison between different eras of humanity and their "fight or flight" responses. It seems to align with the question's context.

D) Adrenaline to heart failure: This option contrasts two different physiological phenomena and does not directly address the "fight or flight" response.

Considering the above analysis, the answer that best fits the author's explanation is C) modern man to cavemen. This comparison contextualizes the understanding of the "fight or flight" response by contrasting the experiences of modern humans with those of our early ancestors.
