Sorry I don’t know how to answer this
Authors often vary the types of phrases and clauses they use in order to add interest to their writing
Your answer is B) just got done taking the test and got results back.
The correct answer is present progressive.
It means that there is some progression, that something is going on at the moment when this sentence is taking place. So, they are currently climbing to the top of the Aztec temple.
Present emphatic would be 'they do climb,' basic present would be 'they climb,' and present perfect would be 'they have climbed.'
Sentace that requires work. A comma is needed after song.
