Stimulus

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 The population today is 270 snow monkeys and is expected to continue growing.

What this question is testing

Most Supported

Anticipate

The cleanest pattern in the stimulus is the before-and-after: monkeys went to orchards before, and stopped going once Suzuki put soybeans in their mountain habitat.

Evidence

That sequence tells us a lot. The monkeys' trips out of the mountains looked like food-seeking — and once food was easy to get at home, the trips stopped.

Goal

Find the answer that follows from this: the monkeys leave the mountain when food is scarce there, and stay home when it is plentiful.

Answer choices, explained

  1. Correct93% picked this

    Snow monkeys do not feed outside of their mountain habitat when food is readily

    Why this is right

    This follows directly from the before-and-after pattern. When food was not readily available in the mountain habitat, the monkeys roamed out to feed in apple orchards. Once Suzuki started providing soybeans in the mountain habitat — making food readily available there — the monkeys stopped raiding the orchards. That is exactly what this answer claims: snow monkeys do not feed outside their mountain habitat when food is available within it.

  2. Unsupported1% picked this

    For snow monkeys, soybeans provide more complete nutrition than

    The stimulus says nothing about how soybeans compare to other beans nutritionally. The monkeys ate soybeans because Suzuki provided them; we have no information about which beans are most nutritious or whether the monkeys would behave the same way with a different bean.

  3. Unsupported4% picked this

    In feeding soybeans to the monkeys, Suzuki did not intend to provoke the phenomenal population

    The stimulus tells us what Suzuki did but not what he intended. Whether the population growth was a goal, a surprise, or a regret to him is simply not addressed. Most-strongly-supported answers cannot rely on the unstated motivations of people in the stimulus.

  4. Unsupported1% picked this

    Snow monkeys eat apples only if there is no other fruit

    The stimulus says monkeys roamed to apple orchards before being fed soybeans. It does not tell us anything about other fruit or rank apples among other foods the monkeys might eat. This answer makes a much sharper claim — that monkeys eat apples only when no other fruit is available — that the stimulus simply does not establish.

  5. Unsupported0% picked this

    Feeding soybeans to snow monkeys has proved to be an environmentally

    Whether feeding the monkeys was environmentally unsound is a value judgment the stimulus does not make. The population growth is described neutrally; the stimulus does not call it harmful or weigh costs against benefits.
