Explanation:

A simple subject is the main word or words in a subject. It does not include any of the modifiers that might describe the subject or conjunctions that connect multiple simple subjects.

Some sentences contain multiple simple subjects. So "owl" is a simple subject in this sentence, and "elephant" is also a simple subject in it.
