Water quality has improved. There are too many trees. The temperature is too cold. Housing developments have replaced fields.
I gave my students this multiple choice question: The snowshoe hare was once common in Maryland. In 1986, researchers in the state noted that the snowshoe hare was no longer found in Maryland. Which statement best explains why the snowshoe hare is no longer found in Maryland?

Only one answer is correct among these 4 choices:
- Water quality has improved.
- There are too many trees.
- The temperature is too cold.
- Housing developments have replaced fields.

Could you tell me which one is correct?

Housing developments have replaced fields.
