is the sentence:
"By using a statement that began with 'I,' Ramon was able to state his feelings clearly."
a simple sentence or a complex sentence?
It's complex. Here's why:
independent clause = "Ramon ... clearly."
dependent clause = "that began with 'I'"
The rest is a phrase, but phrases don't count when you're determining simple (1 ind. clause) or compound (2 ind clauses) or complex (1 ind. + 1 dep. clause).
