Quarrying is cited as an example to show that ______.
A．there will be little difficulty obtaining funds for research
B．underwater research should be completed as soon as possible
C．damage to the sea bed has not been recorded accurately so far
D．the use of scanners may have practical benefits for industry
参考答案
正确答案：D
解析：这是道细节题。从最后一段的“In addition，commercial applications are a real possibility． Aggregates for the construction industry are becoming increasingly expensive，and bathymetry scanners could be used to identify suitable sites for quarrying this material．”另外，这种技术还很有可能被用到商业中去。建筑行业的骨材变得越来越贵，而深海测量扫描机可以用来辨别出适合采石这种材料的场所。绘制海床图还可以辨别出哪里是稀少植物和贝壳类动物安家的地方。因此我们可以看出答案为D。
