In little more than a decade, Argentina has become the world’s leading exporter of honey, with nearly 90,000 tons a year sold to foreign markets, almost half of which going to the United States.

A. with nearly 90,000 tons a year sold to foreign markets, almost half of which going
B. with the sale of nearly 90,000 tons a year to foreign markets, and almost half of it that goes
C. with the sale to foreign markets of nearly 90,000 tons a year, with almost half of it going
D. selling nearly 90,000 tons a year to foreign markets, and almost half of it goes
E. selling nearly 90,000 tons a year to foreign markets, with almost half going

Answer: E

E的with almost half going....是什么功用啊

还有BCD的it都是指honey吗

那A的which又是代谁呢?

谢谢

表状态伴随或补充说明，这里是后者

BCD中it只能指代honey故错误，应该去指代tons

which用法错，有指代markets的嫌疑，实际上也应指代tons

can "it" in BC refer to "the sale"?

B、C的 it 是指代 the sale，和D不同。

B、C错的其中一个原因是
        动词sell 优于
        名词
        sale
