Question

peers who did not share the same opinion about the topic. in other words,
they were told to be true to themselves.
the students heartbeats and blood flow were measured during the
experiment. the researchers discovered that the students arteries
expanded, letting more blood flow to all the bodys tissues. according to
seery, more blood primes us for movement. it supplies us with extra
energy, making us more alert and able to deal with challenges. this
shows that the students experienced the situation as a positive challenge.
sticking up for our beliefs in the midst of opposition can become a
positive experience, seery concludes. the study highlights that if you
make expressing your individuality your goal, conflict doesnt have to feel
uncomfortable.
how does having more blood flow to the bodys tissues help humans?
it creates a positive challenge.
it warns the brain about danger.
it makes the heart beat less.
it raises the bodys awareness.

Explanation:

The text states that more blood flow supplies extra energy, making people more alert (which is related to raising awareness). Option A is incorrect as the positive challenge is the situation the students experienced, not the direct effect of more blood flow. There is no mention of warning the brain about danger (Option B) or the heart beating less (Option C) in relation to more blood flow.

Answer:

It raises the body’s awareness.
