A student is editing a complex sentence to ensure it maintains parallel structure. The original sentence reads: 'The company's goals include increasing profits, to expand into new markets, and developing innovative products.' Which revision correctly applies parallel structure?

  1. AThe company's goals include to increase profits, expanding into new markets, and to develop innovative products.
  2. BThe company's goals include to increase profits, to expand into new markets, and developing innovative products.
  3. CThe company's goals include increasing profits, expanding into new markets, and developing innovative products.
  4. DThe company's goals include increasing profits, expansion into new markets, and the development of innovative products.
Show answer & explanation

Correct answer: C. The company's goals include increasing profits, expanding into new markets, and developing innovative products.

Parallel structure requires that items in a series or comparison have the same grammatical form. The original sentence mixes gerunds ('increasing') with an infinitive phrase ('to expand') and another gerund ('developing'). Option A uses a consistent gerund form ('increasing,' 'expanding,' 'developing') for all items in the list, correctly applying parallel structure.

Why the other options are wrong

  • A. This option incorrectly mixes infinitive phrases ('to increase,' 'to develop') with a gerund ('expanding'), violating parallel structure.
  • B. This option incorrectly mixes infinitive phrases ('to increase,' 'to expand') with a gerund ('developing'), violating parallel structure.
  • D. This option mixes a gerund ('increasing') with noun forms ('expansion,' 'development'), violating parallel structure.

Parallel Structure

The repetition of a chosen grammatical form within a sentence. By making sure all compared or listed items are in the same grammatical structure, parallel structure creates a sense of rhythm and balance.

  • Applies to words, phrases, or clauses in a series.
  • Ensures grammatical consistency.
  • Enhances clarity and readability.

Memory trick: Parallelism is like a balanced scale: all parts must match weight and form.
