【分析解答题】　Questions 11 to 15 are based on the following passage:
About 16 million people in ale United States have lost some of their hearing. About two million others are extremely or completely deaf. They cannot hear speech or most other sounds in their everyday life, even with a hearing aid to make sounds louder.
There are several kinds of hearing loss. The first kind results from disease or injury to the outer or middlepart of the ear. The damage prevents sound waves from reaching the inner ear. Usually, this form of hearing loss is not extreme. And a hearing aid or medical treatment call often restore hearing. A second kind of hearing loss involves the nerves. It is caused by damage to the inner ear. A loud noise or disease may destroy some of the tiny nerve cells that carry sound. People suffering this kind of damage may lose the ability to hear some sounds, high or low. The third kind of deafness is called a central hearing loss. It is caused by damage to the hearing nerves leading to the brain or in the brain itself.
Deafness is the most common bodily disability in America. Often nothing can be done to stop it. But manycases can be prevented. One simple thing is responsible for most hearing loss. That one thing is noise. Telephone bells, loud music, machines. In industrial countries, especially, these things make the world very noisy. Studies have shown that old men in quiet African villages have much better hearing than young people in America. Other sources of deafness include accidents, drugs and illnesses.

【单选题】一个关于世界海底资源开发问题的世界会议建议，将对所有通过海底开矿、在国际水域的食品捕捞或其他的发展形势而对这些资源的使用征收一种国际税，税率固定在一个盈利百分比上。税收的所得将用来支持世界最贫穷国家的工业发展。这项计划，如果被采纳的话，将可能停止所有海底资源的未来发展，因为失去了盈利刺激，计划设置的税将使工业国家对开发这些有价值但很遥远的海底资源进行投资失去信心。

A．哪类发展计划将被计划设置的税收支持
B．提出的税率将是从海底资源开发中得来的盈利的百分之几
