Answer:
1. If you give me a reason. Dependent clause.
2. After months of research. Dependent clause.
3. I enjoy ice cream. Independent clause.
4. John hit the base ball. Independent clause.
Step-by-step explanation:
An independent clause is a group of words that form a complete and meaningful sentence. It can stand on its own and can be accepted as a full sentence. On the other hand, dependent clauses are those words that cannot stand on their own as a sentence and needs to be paired or put with independent clauses to be a full, meaningful sentence.
In the given options, sentences 1 and 2 are dependent clauses as they do not form a complete and meaningful sentence. Sentences 3 and 4 are complete sentences and thus, are independent clauses.
