7. Evidence Which sentence from the passage best supports the idea that the polar bear's body suits its home?

   Young polar bears are called cubs. One reason the polar bear survives is a thick layer of fat called blubber, which keeps it warm in freezing water. (Blubber means a thick layer of fat under the skin.) It also has wide, furry paws, which spread its weight so it does not sink into snow or break thin ice. Under its white fur, a polar bear's skin is black, which helps it soak up heat from the sun. Its food includes seals, fish and bird eggs.
8. Inference Based on the passage, why would the polar bear have trouble surviving somewhere near fresh water?

   It would grow too big. It would have nothing to do all day. Its young would be called something else. Its body and habits are suited to a place that is freezing cold.
