21．【A】這是一道例證，按照常規(guī)套路文中的例子，所要證明的主題應(yīng)該在例子之前，所以定位例子的前一句，Americans are willing to tolerate time-consuming security protocols in return for increased safety. 關(guān)鍵信息是tolerate time-consuming security美國(guó)人愿意忍耐耗時(shí)的安檢，對(duì)應(yīng)A選項(xiàng)的內(nèi)容，同義替換。

This allows the TSA to focus on travelers who are higher risk, saving time for everyone involved. 根據(jù)指代句的內(nèi)容，使用use expedited screening lanes這種方法，可以達(dá)到這樣一種后果saving time for everyone involved.節(jié)省大家的時(shí)間，所以這道題答案應(yīng)該選擇更快。南京考研補(bǔ)習(xí)班有哪些
