Question

which of the following shows the correct use of a comma? i went to bed early last night, and this morning i woke up rested and energetic. i went to bed, early last night and this morning, i woke up rested and energetic. i went to bed early last night and this morning i woke up rested, and energetic.

Explanation:

To determine the correct comma use, we analyze each option:

• First option: The comma is used before the coordinating conjunction "and" to separate two independent clauses ("I went to bed early last night" and "this morning I woke up rested and energetic"), which follows the rule for using commas with coordinating conjunctions to join independent clauses.
• Second option: The commas after "bed" and "morning" are incorrect as they disrupt the natural flow of the sentence; "early last night" is an adverbial phrase modifying "went to bed" and should not be separated by a comma, and "this morning" is part of the second clause and doesn't need a comma there.
• Third option: The comma before "and" is incorrect because "rested" and "energetic" are adjectives in a compound predicate, and commas are not used before "and" in a compound predicate (unless there's a series of three or more items).

Answer:

The first option: "I went to bed early last night, and this morning I woke up rested and energetic."
