Answer 2

The best version of the sentence is B) Never one to settle down, Walton has worked as a truck driver, a welder, and a lifeguard--all in the past two years.

This sentence is the best structured since it applies a parallel structure. Parallel structure or parallelism in writing is the repetition of a pattern within the sentence. In this case, the repetition of the structure is present in the use of the verb phrase has worked, followed by as a truck driver, a welder, and a lifeguard. This structure balances writing and gives equal importance to all the occupations that are mentioned.
