Ring Formation Mechanism

[The GreekFreak]

I am currently working in an organic chemistry lab for a summer internship. My mentor gave me this problem today and I can't quite figure it out. I haven't done actual arrow pushing in over a year so I am having trouble. Thank you!

A good place to start is to high light where the starting materials are in the product, and use that to identify which atoms have formed bonds between them. Another question that may help, do you know what the functional group is on the aromatic starting material above the arrow is called?
