In fact, beavers are very timid animals. They like a quiet environment and generally live along the rivers of cold temperate and subboreal forests. They are mostly found in Europe and rarely appear in other areas. Beavers are timid because their self-defense capabilities are relatively weak, so they are generally active at night and rarely leave their burrows during the day. However, beavers are very good at swimming and diving, and are also known as "the civil architects of the animal kingdom". Does anyone know why this is?

options: A. Dam, B. Trap.
The beaver is known as the "civil architect of the animal kingdom" mainly because it is good at building dams. Beavers have their nests underwater, not only to avoid natural enemies on land, but also to take advantage of their good swimming and diving abilities. And they build dams to protect their nests. When the river enters the dry season, the water level will drop. By building dams, beavers can keep the water surface relatively stable and avoid losing the protection of their nests.
In fact, beavers build dams that benefit others and themselves, and are also beneficial to other creatures. Because the dam can maintain a relatively stable water level in the river, a "natural reservoir" is formed in the upper reaches of the dam, creating a good living environment for other animals. Due to the destruction of their habitat, the population of beavers has been reduced. It has been listed in the " World Conservation Union " and is also a first-level protected animal in my country.
