Input: Read this: Greek art has a long and varied history. Greeks have contributed to the visual, literary and performing arts. In the West, ancient Greek art was influential in shaping the Roman and later the modern western artistic heritage.

Input: Read this: Yale's residential college system was established in 1933 by Edward S. Harkness, who admired the social intimacy of Oxford and Cambridge and donated significant funds to found similar colleges at Yale and Harvard. Though Yale's colleges resemble their English precursors organizationally and architecturally, they are dependent entities of Yale College and have limited autonomy. The colleges are led by a master and an academic dean, who reside in the college, and university faculty and affiliates comprise each college's fellowship. Colleges offer their own seminars, social events, and speaking engagements known as "Master's Teas," but do not contain programs of study or academic departments. Instead, all undergraduate courses are taught by the Faculty of Arts and Sciences and are open to members of any college.
Question: Who teaches Yale's residential college's undergraduate classes?

Output: Faculty of Arts and Sciences
