Read the paragraph and then select the correct answer below.
Within the branches of a eucalyptus tree in Australia lives one of God's special creations, the cuddly koala. He is often called a koala "bear," but he is not a bear. He is a marsupial or a "pouched" animal. The koala is native only to Australia. He has large bushy ears, a black nose, and no tail. He would make a nice pet, but he rarely survives in captivity. Once hunted for his fur, the koala now enjoys government protection.
"Within the branches of a eucalyptus tree in Australia you can find one of God's special creations, the cuddly koala."
