America has found most problems it recognized as soluble. China, in its history of millennia, came to believe that few problems have ultimate solutions. America has a problem-solving approach; China is comfortable managing contradictions without assuming they are resolvable.
【正确答案】：美国发现大多数难题都是可以解决的。中国在几千年历史中逐渐认定，几乎所有难题都没有最终解决办法。美国主张解决难题，中国则满足于控制矛盾而不认为矛盾是可以解决的。
