What is one way that the author develops a theme about new journeys?

 However, these journeys are not always simple physical journeys from one place to another. Writers often use journeys as metaphorical representations of life itself. In one way or another, journey metaphors enable writers to express notions of chance and choice, discovery and departure, and search and struggle.

Explanation:

And Buck was truly a red-eyed devil, as he drew himself together for the spring, hair bristling, mouth foaming, a mad glitter in his blood-shot eyes. Straight at the man he launched his one hundred and forty pounds of fury, surcharged with the pent passion of two days and nights.

Explanation:

We need to use a hyphen when we are transforming a group of two words or more into an adjective. That is, when those words characterize a noun and are placed right before it, they should have a hyphen between them.

In this excerpt, red-eyed is characterizing devil, and blood-shot is characterizing eyes. The other options given are not functioning as adjectives to a noun and, therefore, do not need the hyphen.

Check out some examples that show when to use it:

I live in a middle-class neighborhood.

I want to live in a neighborhood that is middle class.
