From Exercise 9 you should know the three ways to fix a sentence fragment:
1) Attaching the fragment to an indpendent clause before or after it.
2) Rewriting it as an independent clause.
3) Adding a comma before the independent clause if the subject and verb are not in it.

Activity: Examine the following sentences.  Correct the sentence fragment errors in your notes.

example:

When she is helping at home. The work is finished sooner. (fragment)
When she is helping at home the work is finished sooner. (correct: dependent clause joined to an independent clause)

1.  The man gave him a deal on the price of the car. Because Grampa knew him.
2.  Our entertainment unit collapsed! While the television is on the table. We have to eat in the living
     room.
3.  Since the earth goes around the sun. We have a sunrise and sunset.
4.  I couldn't find a job in Halifax. Then I decided to move to Toronto.
5.  Because the job opportunities were limited.
