When primatologist Akira Suzuki began studying snow monkeys in the 1950s, he found that they often roamed out of the mountains to feed in apple orchards. After a decade of observing this behavior, Suzuki began to feed the monkeys in their mountain habitat by providing them with soybeans to eat. The monkeys no longer raided the orchards. When Suzuki began his work, 23 snow monkeys lived in the region he studied. The population today is 270 snow monkeys and is expected to continue growing.

Summary
Primatologist Suzuki found that monkeys often roam out of their mountain habitat to feed in apple orchards. After studying this behavior for a decade, Suzuki began feeding the monkeys in the mountains with soybeans, after which the monkeys no longer ate from the orchards. When Suzuki started, 23 monkeys lived in the region, which has grown to 270 today.

Strongly Supported Conclusions
Feeding monkeys in their natural habitat led them to stop leaving their habitat for other sources of food.

A
Snow monkeys do not feed outside of their mountain habitat when food is readily available within it.
This is strongly supported because although the snow monkeys left their habitat to get apples at one point, they stopped doing this when Suzuki fed them soybeans in their natural habitat.
B
For snow monkeys, soybeans provide more complete nutrition than other beans.
This is unsupported because we don’t have any way of comparing soybeans to a different type of bean.
C
In feeding soybeans to the monkeys, Suzuki did not intend to provoke the phenomenal population growth that resulted.
This is unsupported because we don’t know what Suzuki’s intentions were when beginning this experiment.
D
Snow monkeys eat apples only if there is no other fruit to eat.
This is unsupported because we don’t know whether or not the monkeys would choose an apple or another fruit if they had equal access to both.
E
Feeding soybeans to snow monkeys has proved to be an environmentally unsound policy.
This is unsupported because we don’t know if the impact on the environment was negative due to feeding the monkeys soybeans.
