I’ll give brainlist to who ever answers correctly The year is 2186. Humankind has taken to living
underground during a decades-long nuclear winter. There
is no government and no form of widespread
communication. Isolated pockets of individuals live in self-
sustaining shelters or caves, each group barely managing
to subsist.

Based on this passage, which statement best suggests that the story's
setting is a dystopia?

A. A disaster has caused people to adapt their lifestyles.

B. Humans are isolated from one another.

C. An authoritarian government controls people's lives.

D. Not everyone has equal access to scarce resources.

D.  Not everyone has equal access to scarce resources.

Explanation:

Dystopian aims to portray a story that is as dehumanizing and unpleasant as possible.

If not D, then it is B.

The book Red Rising is a dystopian novel, the characters do not all have equal access to scarce resources. (It's a good book, I recommend it lol)

b. they require a huge investment of time, dedication ,training, and patience almost from the day they are born.
