Read and study Subject and Verb in this website.

Locate the verb first; ask yourself what's happening? what's the action?
Then ask yourself who or what ________ (<~~insert verb there)?

Let me know.

Answer 2

I hope you came up with these:
thrombosis = simple subject
was treated = simple predicate (main verb)
