Which is the best decision regarding the underlined portion of sentence 5 (reproduced below)?
Eventually the operation became a major employer, providing year-round jobs for about two hundred people and up to four hundred part-time jobs during harvest season coming after growing season.

Deleting the underlined portion results in a clear, economical sentence.
The other choices are incorrect because “coming after growing season,” “when the crops were ready to pick,” and “after the produce had ripened” are unnecessarily wordy and somewhat redundant additions to the sentence given that “harvest season” already suggests what each of these choices introduces.
