Practice Questions
Question 1
What punctuation is needed?
Show Answer
Add comma after "raining"
Because it was raining, we stayed inside. (Dependent clause first needs comma)
Question 2
Is this an independent or dependent clause?
Show Answer
Independent Clause
It has a subject (dog), verb (barked), and expresses a complete thought.
Question 3
Is this an independent or dependent clause?
Show Answer
Dependent Clause
It starts with "when" and doesn't express a complete thought. What happens when the bell rings?
Question 4
Does this sentence need a comma? Why or why not?
Show Answer
No comma needed
The dependent clause "if I have time" comes AFTER the independent clause, so no comma is typically needed.
Question 5
Add the correct punctuation.
Show Answer
Although she was tired, she finished her homework.
Comma after "tired" because the dependent clause comes first.
Question 6
Is this a complete sentence? Why or why not?
Show Answer
Not a complete sentence
This is a dependent clause (starts with "since"). It needs an independent clause to complete the thought.
Question 7
Why is the comma used here?
Show Answer
Comma before "and" joins two independent clauses
Both parts could stand alone as sentences. When joining with "and," use a comma.

Where should the comma go?
Show Answer
Before the game started, the players warmed up.
