The narrator is brisk and businesslike;Wheeler takes his time is the answer
The correct answer is <span> A.Once things are done, there is no need to dwell on them, to worry about them, or to decide who is to blame.
Parallel structure means that the same form of a word is used throughout a sentence - here, the infinitive form of verbs is used: to dwell, to worry, to decide.
The rest of the sentences change the form of a word and are not consistent, which is why they don't have parallel structures. </span>
I believe that the answer you are looking for would be B. Here are some reasons why I think so:
1. <span>The twins represent the two ways of the world which are in all people. This is meaning that it is going directly with choice B, and they compare them
2. </span><span>The right-handed twin became angry and resentful. He was the truthful twin who always did the right thing. The left-handed twin was deceitful and did everything backward. You could never trust him. In this little bunch of sentences right here, It's doing exactly what B says, it's comparing the two sides of human nature.
