I'll check only one more of your answers.

Is it A

To identify the sentence that contains a dependent clause, we need to understand what a dependent clause is. A dependent clause is a group of words that contains a subject and a verb but does not express a complete thought. It relies on the main clause to complete its meaning.

Let's analyze each sentence:

A. My mother, who never wastes anything, rinsed and saved the take-out boxes.
In this sentence, the dependent clause "who never wastes anything" is providing additional information about "my mother." However, it cannot stand alone as a complete sentence.

B. We were running late, and we had to skip stopping by the post office.
This sentence does not contain a dependent clause because both "We were running late" and "we had to skip stopping by the post office" are independent clauses that can function independently as separate sentences.

C. I have never been to New York before this spring.
This sentence also does not contain a dependent clause. It is a simple sentence with one independent clause expressing a complete thought.

D. You should take an umbrella to the game.
Similarly, this sentence is a simple sentence with one independent clause expressing a complete thought.

Therefore, the answer is:
The sentence that contains a dependent clause is A. My mother, who never wastes anything, rinsed and saved the take-out boxes.
