单选题

    First two hours, now three hours—this is how far in advance authorities are recommending people show up to catch a domestic flight, at least at some major U.S. airports with increasingly massive security lines.

    Americans are willing to tolerate time-consuming security procedures in return for increased safety. The crash of EgyptAir Flight 804,which terrorists may have downed over the Mediterranean Sea, provides another tragic reminder of why. But demanding too much of air travelers or providing too little security in return undermines public support for the process. And it should: Wasted time is a drag on Americans’ economic and private lives, not to mention infuriating.

    Last year, the Transportation Security Administration (TSA) found in a secret check that undercover investigators were able to sneak weapons—both fake and real—past airport security nearly every time they tried. Enhanced security measures since then, combined with a rise in airline travel due to the improving economy and low oil prices, have resulted in long waits at major airports such as Chicago’s O’Hare International. It is not yet clear how much more effective airline security has become—but the lines are obvious.

    Part of the issue is that the government did not anticipate the steep increase in airline travel, so the TSA is now rushing to get new screeners on the line. Part of the issue is that airports have only so much room for screening lanes. Another factor may be that more people are trying to overpack their carry-on bags to avoid checked-baggage fees, though the airlines strongly dispute this.

    There is one step the TSA could take that would not require remodeling airports or rushing to hire: Enroll more people in the PreCheck program. PreCheck is supposed to be a win-win for travelers and the TSA. Passengers who pass a background check are eligible to use expedited screening lanes. This allows the TSA to focus on travelers who are higher risk, saving time for everyone involved. The TSA wants to enroll 25 million people in PreCheck.

    It has not gotten anywhere close to that, and one big reason is sticker shock: Passengers must pay $85 every five years to process their background checks. Since the beginning, this price tag has been PreCheck’s fatal flaw. Upcoming reforms might bring the price to a more reasonable level. But Congress should look into doing so directly, by helping to finance PreCheck enrollment or to cut costs in other ways.

    The TSA cannot continue diverting resources into underused PreCheck lanes while most of the traveling public suffers in unnecessary lines. It is long past time to make the program work.

答案:

C

解析:

答案精析:根据题干中的long waits at major airports定位至第三段第二句。此句说到,从那以后,安检措施得到加强,加之因经济增长和低油价造成的搭乘飞机出行的游客增多(a rise in airline travel),导致芝加哥奥黑尔国际机场等主要机场内的安检队伍变长。由此可知,旅客人数的增多导致了主要机场里的长时间等候,答案为C。

错项排除:carry-on bags出现在第四段最后一句。此处说的是,更多的人为了省行李安检费用,会在随身行李里装得满满的,但这里并没有提到新规定,A错。全文并未提到运输安全管理局的效率问题,B错。第三段第一句中提到运输安全管理局进行了一次秘密检查,但并未指出调查频率如何,D错。
