Final answer:
The sentence correctly punctuated is 'Quentin's father gave him a golden pocket watch, which was a priceless family heirloom.' Proper punctuation and grammatical consistency are key when integrating quotations, and concise language is achieved by editing out unnecessary words.
Step-by-step explanation:
When integrating quotations in writing, it is important to maintain grammatical consistency and clear delineation between the author's words and the quoted material. The correct sentence with punctuation that follows these guidelines is: Example 2 - Quentin's father gave him a golden pocket watch, which was a priceless family heirloom. This sentence properly uses a comma to connect a dependent clause, as suggested in Chapter 13's review of punctuation. In contrast, the integration of quotations with signal phrases should include correct punctuation such as commas and quotation marks to separate the author's words from the quoted material, as seen in the explanation on editing for more effective sentences.
Furthermore, the method of reducing wordiness and achieving concise language involves eliminating unnecessary words and phrases. This editing process can include condensing wordy phrases and revising for clear and effective communication, as demonstrated in the example contrasting the 49-word sentence with the succinct 16-word and three-word sentences.
