Which best describes the underlined words in the sentence?
on the next cloudless night, go outdoors and look at the sky.
a.
compound verb
b.
simple predicate
c.
complete predicate

I think the answer is B-simple predicate. I think it's B because the other one also include the word predicate which means to do something- like going somewhere or something example is the boy went to the zoo, and so a completed predicate is 'completed':so not letter C. And finally it's not A because you don't have FANBOYS anywhere in that sentence. 

To be honest i really don’t know but ask some one else they will tell u

Hold one let me think
