Clause	Type
Stephen jumps on the trampoline
Until I hear from you
So that Jack could go to college
The teammates celebrated at center court
After they won the championship

Answer 1

A good technique to use is to begin with the phrase: I know that.

If the sentence makes sense doing that, it's an independent clause. If it doesn't, it's a dependent clause.

Looking at the examples:

1. I know that Stephen jumps on the trampoline - That makes sense. Independent clause
2. I know that until I hear from you - You're still waiting to find out important information. I know that until I hear from you ... what? That's a dependent clause.
