Passage Summary: Baby monkeys like soft surfaces when food is available on both, but they will choose a hard surface if it's the only one that provides food.

Reasoning: Infant monkeys preferred a soft surrogate over a wire one when both provided milk, but they preferred a wire surrogate with milk over a soft one without it.

Analysis: This stimulus presents two controlled scenarios to rank the monkeys' priorities. In the first case, with food held constant, the monkeys show a clear preference for comfort (the suede covering). In the second case, when comfort and food are pitted against each other, food wins out. We are looking for a synthesis that acknowledges both factors but recognizes the hierarchy. A supported statement will likely suggest that while physical comfort is a preference for these infants, the availability of nourishment is a more decisive factor in their choice.
