Passage Four
Elephants who paint aren’t new. Paintings by Ruby, an Asian elephant who lived at the Phoenix Zoo in Arizona, sold for up to $ 5,000 in the late 1980s, said Dick George, a consultant with the zoo.
"Ruby was about seven months old when she first came to the zoo," said George. "She lived with a goat and some chickens, but she didn’t have an elephant companion for a number of years. She spent a lot of time drawing in the dirt with a stick to make her days more stimulating. Her keeper bought her some art sup- plies." George said, "Ruby was excited about painting right from the beginning."
The elephants at the art academies in the Southeast Asia are taught to hold a paintbrush with the tip of their trunks. Initially, the keeper guides the elephant’s trunk over the canvas(画布) and offers rewards for good performance.
"It only takes a few hours to a day to teach them," said Mia Fineman, an art historian whose book When Elephants Paint is an illustrated history of the Asian Elephant Art and Consrvation Project.
A．She used a stick to draw in the dirt.

C．She stimulated herself every day.
D．She painted with her keeper’s art supplies.
