Answer:
1.) "Gene calculates the area of the room." This is an independent clause
2.) "If he measures and calculates correctly." This is a dependent clause
3.) "Because the rain was so heavy." This is a dependent clause
4.) "Daisy drove the yellow car home." This is an independent clause
Explanation:
An independent clause is a group of words that can <em>stand on its own as a sentence</em>: it has a subject, a verb, and is a complete thought.
A dependent clause does not express a complete thought and <em>cannot stand on its own as a sentence.</em>
