答案解析

正确答案是：B。这是一道细节题。文章最后一段第一句话就提到：此外，北海道的一位研究员Takeji Kobata开发了一种划时代的技术，他通过燃烧废弃轮胎制造出活性炭。所以B是正确答案。
　　参考译文
　　轮胎回收率
　　1993年，日本的轮胎回收率已达93%。在这里，废弃的轮胎以三种方式被回收再利用。最常见的一种回收利用方式是按照它们的原样——它们本来的形状——将其重新用作学校及公园的操场娱乐设施，有时这些轮胎还被用在一些“新干线”列车的铁轨上以减少震动。
　　废弃轮胎的另一种常见的回收再利用方式是从它们中间提取橡胶加工成新产品。一心致力于轮胎回收再利用研究的Muraoka橡胶公司总裁Minoru Muraoka说：“你可以百分之百地、无数次地回收橡胶。用来做轮胎的橡胶韧性很强÷所以从废弃轮胎中提取出来的橡胶回收再利用的用途也就很多。”除了将提取的橡胶重新用来制造轮胎外，它还被用于制造薄片状橡胶，另外，橡胶碎料还被用来制造房瓦及人行道边板，因此也能美化我们的城市。废弃轮胎的第三种用途是作燃料。现在，有一半的废弃轮胎被用作燃料，为那些需要大量热能的建筑设施服务。
　　此外，北海道的一位研究员Takeji Kobata开发了一种划时代的技术，他通过燃烧废弃轮胎制造出活性炭。这种从轮胎中制造出来的活性炭与市场中现有的其他活性炭相比，质量更好，吸收力更强。用Kobata开发的这种方法，一个重7千克的汽车轮胎可以制出1.5千克的活性炭。Kobata已在美国、加拿大和台湾获取了生产专利，并向英国、法国、德国和巴西的公众开放已经获得专利权的加工过程．

1 　　Soviet-American Relations　　In the fall of 1946. President Truman asked for a comprehensive study of Soviet- American relations,which he knew would be the central problem of American foreign policy. The result was an important state paper prepared through the Secretary of State(国务), the Secretary of War. the Attorney General(检察长). the Secretary of the Navy, Fleet Adrmiral(海军司令) Leahy (who had been Roosevelt's chief military adviser), the Joint Chiefs of Staff(参谋长联席会议主席). Ambassador Edwin W．Pauley (in charge of negotiating postwar reparations), the Director of Central Intelligence(中央情报局局长), and other persons with special knowledge of foreign affairs.The document was imposing in its scope and depth, comprising nearly a hundred thousand words and divided into an introduction and six sections. It dealt with Soviet foreign policy, Soviet-American agreements, Soviet violations of its agreements with the U. S.,conflicting views on reparations, Soviet activities affecting American security, and U.S. policy toward the Soviet Union.
　　This study Truman asked for was drafted on the premise (前提) that only through an accurate understanding of the Soviet Union would the U. S. be able to make and carry out policies that would re-establish international order and protect the U. S. at all times. The key, according to the study; was to realize' that Moscow's leaders adhered to the Marxist theory of ultimate destruction of capitalist states by communist states, but that they sought to postpone the inevitable conflict while they strengthened and prepared the Soviet Union for its clash with the　Western democracies: The study said Moscow's main concern regarding the other nations of Western Europe was to prevent the formation of a Western　bloc (集团). It noted, too, that Red Army troops and Russian planes in combat readiness outnumbered American units opposite them in Germany, Austria, and Korea in overwhelming strength, placing U.S.forces literally at the mercy of the Soviet government.The text associates President Truman with_________

A．peace with hono

B．anti-Communist sentiment

C．the long-standing Cold, War

D．Western imperialism (帝国主义)
