    When judging animal intelligence, scientists look for insight, which they define as a flash of sudden understanding. When a young gorilla could not reach fruit from a tree, she noticed crates scattered about the lawn, piled them and then climbed on them to reach her reward. The gorilla’s insight【T10】______ without trial and error. The ability to use tools is also an important sign of intelligence. Crows use sticks to pry peanuts out of cracks. The crow exhibits intelligence by showing it has learned what a stick can do. Likewise, otters use rocks to crack open crab and, in a series of complex moves, chimpanzees have been known to use sticks to get at favorite snack-termites. Many animals have learned to communicate using human language. Some primates have learned hundreds of words in sign language. One chimp can recognize and correctly use more than 250 abstract symbols on a keyboard and【T11】______ and can understand the difference between numbers, colors, and kinds of object.
    The research on animal intelligence raises important questions. If animals are smarter than once thought,【T12】______ ? Would humans stop hunting them for sport or survival?

Finding the answer to these tough questions makes a difficult puzzle even for a large-brained, problem-solving species like our own.
