11. Independent clause: Jason decided to stay up late; Subordinate clause: because he had a lot of homework to do; Type: Complex
12. Independent clause: If you hurry, we might get to school on time; Subordinate clause: (none); Type: Simple (Note: "If you hurry" is a conditional clause, but the sentence structure is simple because it's not a dependent clause modifying the main clause in a complex way. The sentence is a conditional statement, but the clause "If you hurry" is not a subordinate clause in the traditional sense of modifying a main clause. It's a conditional clause that stands alone as a condition for the main clause. However, in this context, it's often considered a subordinate clause. Let's re-evaluate: "If you hurry" is a dependent clause, and "we might get to school on time" is the independent clause. So, it's a complex sentence.)
13. Independent clause: Although Monica had a cold, she went to school; Subordinate clause: because she had a test; Type: Compound-Complex
14. Independent clause: While washing the car, Todd slipped on the soap and fell; Subordinate clause: (none); Type: Simple (Note: "While washing the car" is a participial phrase, not a subordinate clause. The sentence is simple because it has one independent clause.)
15. Independent clause: Dad takes the train to work; Subordinate clause: even though he has a car; Type: Complex
16. Independent clause: After Mom arrived, she put the disk in the DVD player; Subordinate clause: (none); Type: Simple (Note: "After Mom arrived" is a subordinate clause, and "she put the disk in the DVD player" is the independent clause. The second part "and we watched a great movie" is another independent clause, making it a compound sentence. Let's re-evaluate: "After Mom arrived" is a subordinate clause, "she put the disk in the DVD player" is an independent clause, and "we watched a great movie" is another independent clause. So, it's a compound-complex sentence.)
17. Independent clause: Even though his heart pounded with dread, Ben bolted up the stairs; Subordinate clause: (none); Type: Simple (Note: "Even though his heart pounded with dread" is a subordinate clause, and "Ben bolted up the stairs" is the independent clause. The second part "and he checked out the strange noise" is another independent clause. So, it's a compound-complex sentence.)
18. Independent clause: Molly baked brownies; Subordinate clause: since she had nothing else to do; Type: Complex
19. Independent clause: Karen made a list of what was needed; Subordinate clause: and she double-checked it so she wouldn't forget anything; Type: Compound-Complex
