B
When a robin(a kind of bird) sees itself in a window or mirror,it seems to think the reflection(映像) is another robin. The bird may hit the glass,trying to drive the other bird away.
In the 1970s,Dr. Gordon Gallup had an idea. He thought more intelligent(智力的) types of animals might know that their reflections show themselves. To find out,he created an experiment called the mirror test. If an animal passes the test,scientists say that it has "self-awareness". In Dr. Gallup's experiments,chimpanzees(黑猩猩) passed,but monkeys failed.
So far,only eight have passed,including humans. Four of them are in the chimpanzee family. Magpies(喜鹊),dolphins,and elephants also passed.
The mirror test has four stages.

In studies with children,a research group put stickers on the foreheads of children who just learned how to walk when they weren't paying attention. By the age of two,most could notice the sticker in a mirror and take it off.
In Dr. Reiss's dolphin study,the researchers put marks on two dolphins' heads. Both dolphins noticed the mark in a mirror. One of them swam to the side of the pool and tried to rub the mark off. A mark placed on elephants' heads gave similar results.
"Animals that pass the mirror test have a lot in common," Dr. Reiss says. "They all have large,complicated brains compared to their body size. They all live in social groups and work with each other. They care about others." The mirror test can't make us know about every animal's intelligence. (Dogs might be self-aware,but they use their noses much more than their eyes.)
Dr. Reiss says self-awareness is only one form of intelligence. "Many highly social animals communicate in their own ways. It isn't about who is more intelligent. It is about what kind of intelligence they show."
