In the United States, the beaver is one of the largest members of the rodent family. This animal  can manipulate the environment to suit its own needs and can even construct its own home. Beavers are vulnerable to predators when they are on dry land, so they need deep water for safety. If nearby  water is not deep enough, a beaver will build a dam to make the water deeper. A beaver dam can be  very large and can contain thousands of pieces of wood cut by the beaver. Beavers even cut down small  trees to eat the bark, leaves and twigs. Because beavers are members of the rodent family, they have  four incisor teeth in the front of their mouths that never stop growing, so beavers must continuously  chew on wood to keep their teeth from growing too long. 

Why must beavers continually chew on wood?

• to satisfy their hunger during the winter 

   

• to keep their teeth from growing excessively

• because they are unable to find water lily tubers 

• to cut down trees so they can build a lodge

Beavers have other unusual characteristics that make them fascinating. Some of these flat-tailed  creatures build homes called lodges while some live in holes in the riverbanks. Years ago, beavers were  prized for their fur and so many were trapped that they almost became extinct. Hunters found the beavers by looking for their dams and lodges, so some beavers stopped building and began living in riverbank holes. Even though beavers are now protected, some beavers still live in these holes, but most  build lodges. Even beavers that build lodges keep a few riverbank holes and escape tunnels to use in  case of an emergency. 

According to the passage, why did some beavers begin living in riverbank holes?

•   They were easier to build than tree branch lodges. 

• So that hunters could not use the lodges to find them. 

• Because the holes stay warmer in winter than lodges. 

• Because more beavers can live together in a hole than a lodge.

Another interesting feature of beavers is that they will store a bunch of branches under the  water near their lodge to use as food during the winter. When their lake or stream is covered with ice,  the beaver has a handy supply of food sealed under the ice. A colony of beavers, which usually consists of five or more, can stay warm in their lodge with their food supply nearby. They can survive in their  lodge for at least four months during the coldest days of winter. When spring comes and the ice thaws,  beavers will feast on water lily tubers, clover and the new green shoots and bark of saplings, or small  trees. Though the beavers eat tree branches and bark, this pruning actually helps some of the trees  grow new branches, making them bushier the next year.

 How do beavers prepare for the winter?

• They build a dam in which to live. 

• They have many babies. 

• They store branches under the water. 

• They grow a thick fur coat.

What unique quality almost caused beavers to no longer exist?
