Question

At first driving requires a lot of concentration, but over time, it just becomes_____.

A．authentic

B．available

C．automatic

D．awake

Answer 1

C

句意:一開始駕駛需要集中精力,但是一段時間后就成為無意識的行為。automatic 意思為“無意識的；不經思考的”，英語解釋為done without thinking about it，這與題干中concentration（the ability to think carefully about something you are doing）相對應。authentic可靠的；真正的；available可用的；有效的；awake 醒著的;清醒的。
