选项 A、The number of protected sites would increase to 54.
B、The protected vegetation types would increase to 54.
C、The land area covered by protected sites would increase by 5496.
D、The cost-effectiveness of protected areas would increase by 54%.
答案 B
解析 根据题干中的replacing just 1 per cent of the least cost-effective areas可以快速定位到第5段第3句。解题关键在于弄清the number指的是什么的数量。答案在上一句找。该段第2句说到，澳大利亚60种植被中只有18种得到了保护，因此可以判断这里的the number指的是受保护植物的数目。因此排除A，选B。
