Many agriculturally intensive areas of the world are beginning to encounter water scarcity problems. As a result, many farmers in these areas are likely to reduce their output as the water supply they need in order to maintain production shrinks. However, one group of farmers in such a region plans to increase their production by implementing techniques for water conservation.
Which of the following, if true, would most strongly support the prediction that the group`s plan will succeed?
- AFarmers who can gain a larger share of the food market in their regions will be better positioned to control more water resources.
- BMost agricultural practices in areas with water shortages are waterintensive.
- COther regions of the world not facing water shortages are likely to make up for the reduction in agricultural output.
- DDemand for agricultural products in the group`s region is not expected to decline.
- EMore than half the water used for agriculture in the farmers` region is lost to evaporation or leakage from irrigation channels.
请问b为什么是削弱呢。。。因为这个地区农业是水资源密集型的，所以采用新技术之后农业能用的水就更多了，就会增强当地农业的产量 不对吗
og对b的解释是，没有证据证明这个技术会为增产而提供更多的水。但节水不就是为了提供更多的水吗。。。
对不起脑子突然堵住了qaq 求解答
