Answer:
Since Erin loves green beans, he grows vegetables.
Explanation:
A complex sentence involves a independent clause and one or more dependent clauses. Independent clauses have one subject and one verb and dependent clauses depend on the independent. So, in this case, you could put he grows vegetables as the independent and since Erin loves green beans as the dependent. To make sense, you should write it as "Since Erin loves green beans, he grows vegetables." Hope it helped.
