3. Independent clause
4. Dependent clause
Step-by-step explanation:
In English language, there are two types of clauses (a group of words that contain subject and predicate) viz; independent clause and dependent clause.
INDEPENDENT CLAUSE is a clause that can stand alone to form a complete sentence, possessing a subject and a predicate.
On the other hand, a DEPENDENT CLAUSE cannot stand alone to form a complete and meaningful sentence, but instead depends on another sentence to make sense. It is often recognizable as they start with subordinating conjunctions such as while, because, when etc.
According to this question, the following are examples of independent and dependent clauses:
1. Because he cannot pick up our son - dependent clause
2. I am typing on the computer - independent clause
3. They will have gone to Disney World - independent clause
4. Before we arrive in Florida - dependent clause
