which of the following sentences is punctuated correctly?
since the store isnt open yet we should find a place to sit.
since, the store isnt open yet we should find a place to sit.
since the store isnt open yet, we should find a place to sit.

Explanation:

Step1: Identify dependent clause

The phrase "Since the store isn't open yet" is a dependent adverbial clause that starts the sentence.

Step2: Apply comma rule

When a dependent clause precedes an independent clause ("we should find a place to sit"), a comma must separate the two clauses.

Step3: Evaluate options

• Option 1: Missing comma after dependent clause, incorrect.
• Option 2: Misplaced comma right after "Since", incorrect.
• Option 3: Correctly places comma after the dependent clause, matching the rule.

Answer:

Since the store isn't open yet, we should find a place to sit.
