Which choice best describes the underlined words in this sentence?

Should you have been walking the dog without a leash?

Underlined is:

Should _____ have been walking

it does not include the word "you" so I just did an under score to represent that.

A- simple predicate

B- complete predicate

C- compound predicate

D- none of the above

I am kinda confused on this one. I have been seeing a lot of different answers for this question.

dentify the choice that best describes the underlined word for questions 5–8.

Both Jewel and Lauryn Hill are known as singers and songwriters.

Ok, that makes sense. Thank you for the link! :)

You're welcome.

sorry but not much help to me. i'm a different question

should have been walking is the verb. Therefore it is the simple predicate.

The complete predicate is "should have been walking the dog without a leash."

But isn't "have been walking" a verbal phrase? Then wouldn't the answer be none of the above?

I found a website, but it would not let me post the url.
It was under Verbal Phrase Examples.

Yes, it's a verbal phrase. But its function in this sentence is as a simple predicate.
