I want to know the answer to the following question:
When was Yale Graduate Schools and Arts and Sciences established?
All the background I'm provided with is that "Yale expanded gradually, establishing the Yale School of Medicine (1810), Yale Divinity School (1822), Yale Law School (1843), Yale Graduate School of Arts and Sciences (1847), the Sheffield Scientific School (1847), and the Yale School of Fine Arts (1869).". Is that enough to answer the question?
Answer: yes
