Read the following passage carefully and then answer the questions that follow.

             Do you have a pet mammal ? If you have a dog or a cat, or a hamster, then you do. You must have seen puppies or kitten feeding from their mother's body.  We are mammals too. All mammals' babies drink milks from their mother's body.
             It may be cold or hot, but  the mammals' bodies stay at the same temperature all the  time. So all the mammals are warm-blooded.
             Mammals have  fur or hair.  The fur can be short, long or straight or curly. They may be lots of it covering every part of the body,  as on bears or dogs, or a few whiskers in one place as on whales and dolphins.
             Unlike other animals , mammals manage to live almost everywhere.  Polar bears live in some of the coldest places in the world.  Camels live in the hottest places.  Dolphins are mammals that spend their whole life swimming in the ocean.  Bats are mammals that often live in dark caves and can fly.
             For mammals home is where food is.  Some mammals feed  vegetables, others hunt for meat, so they can be carnivorous or herbivorous.
