The situation is now becoming so bad that environmentalists feel it many be necessary to shock the world into saving water in a similar way to the shock caused by the oil crises in the 1970’s.
At that time, the oil crisis became such
A. People now pay as much for water as they did 200 years ago.

C. Water now costs as much as it used to.
D. Water now has become more expensive than it was.
