By merging its two publishing divisions, the company will increase (their share of the country's $21 billion book market from 6 percent, a market ranging) from obscure textbooks to mass-market paperbacks.
B from 6 percent to 10 percent its share of the $21 billion book market in the country, which ranges
E to 10 percent from 6 percent its share of the country's $21 billion book market, which ranges
我选择的是E，GWD答案是B。我觉得B最大的问题是which ranges貌似修饰的不是book market 而是country。而E正确使用了which ranges。而且看老外们的讨论，说to**from**这个短语也是存在的，很多人也都选择了E。
请问NN们到底哪个选项才对呢？
拜谢！
