(B)each is exporting to the other one

(D)they are exporting to one another

想請教各位熊熊,關於choice A 為何對及 E 有何錯,
感激不盡！

幾天沒看題目......有生疏感~~~

D E中的they......在原句中沒有複數名詞可以代表.
D的one aonther好像是要三者以上才用.
C應該沒人會選.....
B中的one可以省略,以及突然出現個進行式....

請其他人補充: choice A 為何對

[josephcfan]

Excuse me, can we veiw "the United States and Canada "as plural noun?

我想在AT考試中是不行的,畢竟是要選最好的答案.

我想both 跟 each other感覺有點囉唆.
