求詳解

Answer 1

最佳解答

只能選C，讓smart cards成為主句的主詞，這樣句首的already in wide circulation才合理，是smart cars are in wide circulation。

A的主詞是we，會造成語病：we are in wide circulaiton。

B的主詞是easy solution，也是用語病：easy solution is in wide circulation。

D的主詞是they，因為沒有前句可以參考，無法判定they are in wide circulation的they代表什麼，會造成句意不清楚的毛病。

Answer 2

Let (c)=main clause=smart card,because can be refering to subordinate clause"Already in wide circulation".
