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

   One reason the arctic fox survives is fur that turns white in winter and brown in summer, which helps it blend in with snow or with rocks and plants. (Camouflage means colors or patterns that help an animal blend in.) It also has a short nose, short legs and small ears, which help it lose less heat in the cold. A family may raise more than ten kits in one underground den. To find food, it listens for lemmings under the snow, then leaps up and dives in headfirst to catch them. Arctic foxes can stay warm in temperatures as low as minus 50 degrees Celsius.
8. Inference Based on the passage, why would the arctic fox have trouble surviving somewhere warm and rainy?

   It would grow too big. It would forget how to find its home. It would have nothing to do all day. Its body and habits are suited to a place that is freezing cold.
