Which characteristic is not true of epics?

The heroes are usually flawed in some critical way.

Explanation: To answer this question, just take a classical epic and plug it into the answers. Take The Hobbit, for example. Bilbo, the hero of the story, goes on a journey outside of his normal world. He battles trolls, goblins, and other monsters along the way, and the series Lord of the Rings continues his story with his nephew Frodo, making the epic pretty long. The only choice that does not fit this story is B.

faulty parallelism is a construction in which two or more parts of a sentence are equivalent in meaning but not grammatically similar in form.

the correct version of this faulty parallelism in the sentence is:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.

the problem is the last sentence, the first two have a basic subject+verb+object structure.

so, to give a proper balance to the structure, or better said, to give a parallel structure, we must write a basic s+v+o structure in all three sentences:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.
