Beavers are able to adapt to the changing conditions of all four seasons. Which of the following would threaten the survival of
ELEN [110]

Answer:

C

Explanation:

The question says that beavers are able to adapt to changin questions in each season, so we know that snow in winter, or heat in summer won't bother them. These types of variations in weather are what the beaver is used to. This would eliminate A (July is in summer, so the beavers would expect heat), B (December is in winter, so the beavers would expect freezing conditions), and D (January is in winter, so the beavers expect the snow). That leaves us with C. Fires are not a typical condition for a season- fires aren't expected every fall. Therefore, when there is a fire, beavers will not know what to do. Hope this helps, and feel free to ask me for more clarification!
