单选题 4.  In the 1600s there was intense competition in Europe to discover how to make porcelain. The two groups of Europeans working in China—Dutch merchants and French missionaries—each tried to discover the Chinese manufacturers' secrets. The first French missionary journal, was not published until 1717, several years after European porcelain manufacture began. Therefore, rather than copying the Chinese techniques, the European manufacturers must have learned by experiment.
    Which of the following, if true, provides the strongest support for the argument? ______
【正确答案】 E

   B:和瓷器品质无关。
   C:这进一步说明了欧洲人复制中国技术的可能,削弱。
   D:和原材料无关。
