3 Your heart is pumping at two to three times the normal speed, sending nutrient rich blood to the major muscles in your arms an
d legs. The tiny blood vessels (called capillaries) under the surface of your skin close down (which consequently sends your blood pressure soaring) so you can sustain a surface wound and not bleed to death. Even your eyes dilate so you can see better. Which best describes the purpose of paragraph three in this passage?
A) to describe the way the human body physically responds to stress
B) to describe the typical stresses that a caveman faced
C) to explain how modern stresses differ widely from ancient stresses
D) to differentiate between real stress and false alarm stresses
A) to describe the way the human body physically responds to stress
Explanation:
The excerpt does not describe a specific type of stress, so options B, C and D are already discarded since there's no mention of the type of stress that it would be.
Instead, the text actually gives us a detailed description of how our body works in a situation (any situation) of stress in a very detailed and interesting way.
