The wings of a moth may seem grey and dull to us, but to insects they may appear beautiful, showing colours which we cannot see. (Passage 3)

According to reports in major news outlets, a study published last week included a startling discovery: the nation's Jewish population is in shrinking. The study, the National Jewish Population Survey, found 5.2 million Jews living in the United States in 2000, a drop of 5 percent, or 300,000 people, since a similar study in 1990．What's truly startling is that the reported decline is not true. Worse still, the sponsor of the $6 million study, United Jewish Communities, knows it.

Both it and the authors have openly admitted their doubts. They have acknowledged in interviews that the population totals for 2000 and 1990 were reached by different methods and are not directly comparable. The survey itself also cautions readers, in a dauntingly technical appendix, that judgment calls by the researchers may have led to an undercount. When the research director and project director were asked whether the data should be construed to indicate a declining Jewish population, they flatly answered no. In addition, other survey researchers interviewed pointed to other studies with population estimates as high as 6.7 million.

Despite all this, the two figures—5.2 million now, 5.5 million then—are listed by side in the survey, leaving the impression that the population has shrunk. The result, predictably, has been a rash of headlines trumpeting the illusionary decline, in turn touching off jeremiads by rabbis and. moralists condemning the religious laxity behind it. Whether out of ideology, ego, incompetence or a combination of all three, the respected charity has invented a crisis.

United Jewish Communities is the coordinating body for a national network of Jewish philanthropies with combined budgets of $2 billion. Its population surveys carry huge weight in shaping community policy. This is not the first time the survey has set off a false alarm. The last one, conducted by a predecessor organization, found that 52 percent of American Jews who married between 1985 and 1990 did so outside the faith. That number was a fabrication produced by including marriages in which neither party was Jewish by anyone's definition, including the researchers.

Its publication created a huge stir, inspiring anguished sermons, books and conferences. It put liberals on the defensive, emboldened conservatives who reject full integration into society and alienated ordinary folks by the increasingly xenophobic tone of Jewish communal culture. The new survey, to its credit, retracts that figure and offers the latest survey has spawned a panic created by the last one.

So why did the organization flawed figures once again? Some scholars who have studied the survey believe the motivation then came partly out of a desire to shock straying Jews into greater observance. It's too early to tell if that's the case this time around. What is clear is the researchers did their job with little regard to how their data could be misconstrued. They used statistical models and question formats that, while internally sound, made the new survey incompatible with the previous one. For example, this time the researchers divided the population of 5.2 million into two groups—"highly involved" Jews and "people of Jewish background" — and posed most questions only to the first group. As a result, most findings about belief and observance refer only to a subgroup of American Jews, making comparisons to the past impossible.

We can't afford to wait a decade before these figures are revised. The false population decline must be corrected before it further sours communal discourse. The United Jewish Communities owes it to itself and its public to step forward and state plainly what it knows to be true: American Jews are not disappearing.

According to the passage, which of the following statements is NOT true about the National Jewish Population Survey?

A．It found a decline of 300,000 Jews in ten years.

B．It was carried out by United Jewish Communities.

C．This is the first time United Jewish Communities has made mistakes in the population survey.

D．The reported decline is not reliable.

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 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 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 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 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.
