Which of the following is a compound sentence? We saw pandas during our visit to the zoo.

This is not a compound sentence. It is a simple sentence with a subject ("we") and a verb ("saw") and an object ("pandas"). A compound sentence is made up of two or more independent clauses connected by a coordinating conjunction or a semicolon.

The sentence "We saw pandas during our visit to the zoo" is a simple sentence, not a compound sentence.

To determine if a sentence is compound, we need to check if it consists of two or more independent clauses joined together by a coordinating conjunction (such as "and," "but," "so," "for," or "yet"). Let's examine the given sentence: "We saw pandas during our visit to the zoo."

In this case, the sentence only contains one independent clause ("We saw pandas during our visit to the zoo"), and there is no coordinating conjunction present. Therefore, this sentence is not a compound sentence. It is a simple sentence.
