Answer: If I had been working alongside Elizabeth Cady Stanton, I would have told her how much I admire her.
"I would have told her how much I admire her" is an independent clause because it can stand alone as a sentence. In other words, it contains all the information that is necessary to be a complete sentence. Moreover, the whole sentence ("If I had been working alongside Elizabeth Cady Stanton, I would have told her how much I admire her") is a complex sentence since it combines a dependent clause, which cannot stand by itself, and an independent clause.
