Another activity I enjoy is drawing horses. What is simple subject?
What do you think the simple subject of this sentence is?
Nope, "drawing horses" is part of the predicate.
First, take out the subordinate clause: "(that) I enjoy."
That leaves: "Another activity is drawing horses."
The verb is "is."
Ask yourself WHAT is?
The answer will give you the simple subject.
Right. The simple subject is "activity."
