Conjunctions — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. The bell rang the students rushed outside. Add: The bell rang, and the students rushed outside.
Adding a comma plus 'and' fixes the run-on by making it a proper compound sentence with two joined independent clauses.
2. I was tired, I kept reading my book. Fix: I was tired, but I kept reading my book.
Comma splices can be fixed by adding a coordinating conjunction. 'But' shows the contrast between being tired and continuing to read.
3. We can play outside or we can watch a movie inside.
'Or' joins two independent clauses to offer alternatives, fixing what would otherwise be a run-on.
4. It was raining hard yet we still went to the soccer game.
'Yet' works like 'but' to show contrast and is a FANBOYS conjunction that can fix a run-on between two related clauses.
5. The store was closed so we drove to the next town.
'So' joins two clauses where the second is a result of the first, fixing the run-on with a logical link.
6. My friend called so I went to the door to greet him.
So shows result; call caused door action in this sentence pair.
7. We went home because the rain started pouring down.
Because introduces a reason; rain is the reason we went home.
8. I will pack a snack in case I get hungry on the trip.
In case shows a possible future condition that justifies packing.
9. You should rest until you feel ready to play again.
Until marks a time boundary when the resting can end safely.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.

Run-ons are fixed by adding a comma plus a coordinating conjunction (FANBOYS) that fits the meaning, like 'and' for adding ideas or 'so' for showing a result.
