Limit on Number of Library Books

Currently, students can take out as many books from the library as they want. But I think the library should limit the number of books students can take out at one time to ten. This will prevent students from checking out more books than they need. Sometimes, students take out additional books and never use them. In addition, this plan should help reduce the number of lost books each year. Students often have a hard time keeping track of large numbers of library books, and they often get misplaced.

Sincerely,

Task 3

Reading

Alarm Calls

One way that animals communicate with other members of their group is by emitting alarm signals that warn nearby members of danger in the area. Many species sound an alarm call to warn others of approaching predators. Alarm calls promote the survival of the group by warming others of danger and allowing them to escape. However, sometimes alarm calls convey a deceptive, of false, message to other members of the group. These false alarm calls may frighten other members away from an area, this reducing competition for food or mates.

Explain how the example of vervet monkeys from the lecture illustrates the of alarm calls.
