阅读下面短文，从每题所给A、B、C、D四个选项中选出最佳答案。

Koalas are cute and easy to recognize, with fluffy ears and a large, spoon-shaped nose. They’re popular with people.

They used to be common across Australia, but the last 200 years haven’t been good for them. Their forests have been cut down and burnt in bushfires. Now, koalas are endangered, so it’s necessary to make sure of koala populations by counting（数）them in different areas. This information can be used to find out where help is most needed. Then it’ll become much easier to protect them and their homes.
