Which sentence correctly coordinates a series using parallel gerund phrases?

Answer and explanation

Correct answer: A. The curator's duties include cataloging artifacts, preserving textiles, and guiding visitors.

  1. Step 1: Parallelism requires items in a series to share identical grammatical forms.
  2. Step 2: The sentence 'The curator's duties include cataloging artifacts, preserving textiles, and guiding visitors.' coordinates three parallel gerunds: 'cataloging', 'preserving', and 'guiding'.
Answer
The curator's duties include cataloging artifacts, preserving textiles, and guiding visitors.
Why not the others: The sentence ending 'and to guide visitors' breaks parallelism with infinitive 'to guide'; the sentence with 'the preservation of textiles' shifts to noun phrase 'the preservation'; the sentence beginning 'The curator's duties include to catalog' mixes infinitives, gerunds, and base verbs.
