Context: Read the text about bats.
Several kinds of animals "talk" to one another in the wild. Dolphins whistle, birds sing, and wolves howl. In recent years, researchers have paid more attention to animal "languages," and they have made some surprising discoveries. Egyptian fruit bats, for example, have a very complex way of talking to one another. In fact, they are one of the few animals that direct their calls to another individual. Most animals make calls to their entire group. Bats can also share more complex information than other animals. This is because they have special sounds to communicate specific issues.
Researchers at Tel Aviv University in Israel wanted to learn more about what bats are really saying to one another. First, scientist Yossi Yovel and his team recorded sound and video of twenty-two bats. Fifteen thousand bat calls were collected over a period of seventy-five days. Then, the researchers tried to match each bat call with a behavior. They used special software to help them tell different bat calls apart and decipher the bats' messages.
What Yovel and his team found was astonishing. Egyptian fruit bats are not just making squeaky noises; they are expressing very distinct concerns. One type of call means the bats are arguing over food. Another type of call means the bats are figuring out where they are going to sleep. A third call is used when one bat has gotten too close to another.
The researchers made another startling discovery. A bat can alter the sound of its call when addressing different members of the group. This is similar to how humans may use a different tone of voice when speaking to different people. It turns out that bats use language as a way to communicate their needs to each other, almost like humans do.

A. They can communicate with many kinds of animals.
