Professor C. D. Rock ran out of teasers, so he went to Teaserville to buy some more. After arriving there he went to 6 different stores. He first went to the "Theater" to buy some teasers about movies. He then went to the "ER Hospital" to buy teasers about health, and the human body. Then he went to, in order, the "Art Center," the "Supermarket," and the "Energy Plantation." He then went to one last store. It was one of the following:
A. Library
B. High School
C. Dance Arena
D. Saloon
E. Dog Pound
F. Railroad Station
G. Petting Zoo
H. Carnival
Can you figure out which place Professor C. D. Rock visited lastly?
