Final answer:
The correct way to rewrite sentence 16 with proper punctuation is: 'Looking out over the ocean, we practiced a new song composed during the trip.'
Step-by-step explanation:
To rewrite sentence 16 to show the correct punctuation of a participle, the appropriate choice would be option c. Looking out over the ocean, we practiced a new song composed during the trip. The comma after the introductory participial phrase Looking out over the ocean is necessary to separate it from the main clause and to prevent a run-on feeling to the sentence.
The phrase composed during the trip does not require commas around it as it is essential information that specifies which song was practiced; hence, it is restrictive and commas are not needed.
To correctly punctuate the participle in sentence 16, the option "c" is appropriate: "Looking out over the ocean, we practiced a new song composed during the trip." The comma after "ocean" indicates the separation between the introductory participial phrase and the main clause.
This punctuation style ensures clarity and proper structure, allowing readers to seamlessly follow the narrative. It enhances the flow of the sentence, signifying that the action of looking out over the ocean is connected to the main action of practicing a new song composed during the trip.
Therefore answer is c. Looking out over the ocean, we practiced a new song composed during the trip.
