Answer: [2] He faced insults and difficulties doing this; however, he was determined to continue making money, which he did.
Step-by-step explanation:
Every sentence above comprises of two clauses with some being independent and others being dependent clauses. Sentence two is different from the rest in that it contains three clauses instead of two.
Two of those clauses are independent clauses and the third is a dependent clause. The two independent clauses are: " He faced insults and difficulties doing this" and "he was determined to continue making money". The dependent clause is, "which he did".
