The Quizbowl Resource Center

I found this question on the internet. It was used in a quizbowl competition and was swept by the team that played it. Please tell me the answers.

MASTERPIECES IN THE PRADO
I'll name the artist and you give the title.
5 Hieronymous Bosch
10 Diego Velasquez
15 Francisco de Goya

I found the question here. It was so good that it not only was used in a national tournament--it was used in a write-up of the tournament that focuses on how awesome the tournament was.
