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 securities lines.

Americans are willing to tolerate time-consuming security protocols in return for increased safety. The crash of Egypt Air Flight 804, which terrorists may have downed over the Mediterranean Sea, provides another tragic reminder of why. But demanding too much of air travels or providing too little security in return undermines public support for the process. And it should: Wasted time is a drag on American’s 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一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 airlines 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 fact 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 USA could take that would not require remodeling airports or rushing to hire: En?roll 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 travels who are higher risk, saving time for everyone involved. 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 can't continue diverting resources into understand PreCheck lanes while most of the traveling public suffers in unnecessary lines. It is long past time to make the program work.

Which of the following would be the best title for the text?

• A.Less Screening for More Safety
• B.PreCheck—A Belated Solution
• C.Getting Stuck in Security Lines
• D.Underused PreCheck Lanes

We often use the words "growth" and "development" as if they meant basically the same thing. But this may not always be the case. One can easily imagine instances in which a country has achieved higher levels of income （growth） with little or no benefit coming to most of its citizens （ development）.

In the past, most development policies were aimed at increasing the growth rate of income per capita. Many are still based on the theory that the benefit of economic growth will come to all members of society. If this theory is correct, growth should encourage development.

By the early 1970s, however, the relationship between growth and development was being questioned. A major study by the World Bank in 1974 concluded that it is now clear that more than decades of rapid growth in developing countries has been of little benefit to a third of their population.

The World Bank study showed that increase in GNP per capita did not promise important improvements in such development indicators as nutrition, health, and education. Although GNP per capita did in?deed rise, its benefit came down to only a small part of the population. This realization gives rise to a call for new development policies. These new policies favor agriculture over industry, call for national redistribution of income and wealth, and encourage programs to satisfy such basic needs as food and shelter.

In the late 1970s and early 1980s, the international macroeconomic crises of high oil prices, worldwide recession and the third world debt, forced attention away from programs designed to get rid of poverty. How?ever, the lesson remains: economic growth does not promise economic development. Efforts may be required to change growing output capacity into economic benefit that reach most of a nation's people.

If the passage continues, what would the author most likely discuss in the next paragraph?

• A.How to turn growth into development
• B.How to remove poverty from society
• C.How to decrease the third world debt
• D.How to cope with economic crises
