CATSAGia Andina de Triconos (CATSA), a Bolivian joint venture of the U. S. Dresser Industries and local investors, which had based its investment (19) an allocation under the metalworking program, closed its doors after (20) to penetrate the Andean market after more than two years in operation.The prospect of (21) access to the Andean market, plus protection provided by a 55 percent "ad valorem" common outer tariff on bits sourced from outside the bloc, made the sales outlook seem (22) . However, CATSA’s "monopoly" position in Ancom proved specious. (23) the plant went on stream in 1974, the company was never able to export a single drill bit to the Andean market, and its local sales were (24) a state-owned petroleum company. This market was clearly (25) , since the operation had been based on exporting the bulk of the plant’s 200-unit-per-month capacity to the Andean area.CATSA could not penetrate the Ancom market for several reasons:Although Ancom (26) a 55 percent common outer tariff on third-country imports, some Ancom countries had previously (27) LAFTA (Latin American Free Trade Association) tariff concessions, which take precedence over the Ancom tariffs.Ancom members simply did not (28) the spirit of the metalworking agreement. After the installation of the CATSA facility, plants producing tricorne bits (29) in Peru and Venezuela. Under the metalworking program, participating (30) were committed to prohibiting new foreign investment in allocations of other Ancom countries. But on the question of new investment by local industry, the obligation was only not to encourage it, with no requirement to prevent it. (31) Venezuela, it has no commitment to limit local production or to honour the outer tariff, because it was not yet a member of Ancom when the metalworking agreement was signed and was thus not a (32) to the pact.

26-30 The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones. RTCA, an organization which advises the aviation (航空) industry, has recommended that all airlines ban (禁止) such devices from being used during "critical" stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights. The difficulty is predicting how electromagnetic fields might affect an aircraft’s computers. Experts know that portable devices emit radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not. The fact that aircraft may be vulnerable (易受损的) to interference raises the risk that terrorists may use radio system in order to damage navigation equipment. As worrying, though, is the passenger who can’t hear the instructions to turn off his radio because the music’s too loud. Few airlines want to impose a total ban on their passengers using electronic devices because______.

A. they don’t believe there is such a danger as radio interference
B. the harmful effect of electromagnetic interference is yet to be proved
C. most passengers refuse to take a plane which bans the use of radio and cassette players
D. they have other effective safety measures to fall back on

At the fall 2001 Social Science History Association convention in Chicago, the Crime and Justice network sponsored a forum on the history of gun ownership, gun use, and gun violence in the United States. Our purpose was to consider how social science history might contribute to the public debate over gun control and gun rights. To date, we have had little impact on that debate. It has been dominated by mainstream social scientists and historians, especially scholars such as Gary Kleck, John Lott, and Michael Bellesiles, whose work, despite profound flaws, is politically congenial to either opponents or proponents of gun control.① Kleck and Mark Gertz, for instance, argue on the basis of their widely cited survey that gun owners prevent numerous crimes each year in the Untied States by using firearms to defend themselves and their property. If their survey respondents are to be believed, American gun owners shot 100,000 criminals in 1994 in self-defense—a preposterous number. Lott claims on the basis of his statistical analysis of recent crime rates that laws allowing private individuals to carry concealed firearms to deter murders, rapes ,and robberies, because criminals are afraid to attack potentially armed victims. However, he biases his results by confining his analysis to the year between 1977 and 1992, when violent crime rates had peaked and varied little from year to year. He reports only regression models that support his thesis and neglects to mention that each of ’those models find a positive relationship between violent crime and real income, and inverse relationship between violent crime and unemployment.Contrary to Kleck and Lott, Bellesiles insists that guns and America’s "gun culture" are responsible for America’s high rate of murder. In Belleville’s opinion, relatively few Americans owned guns before the 1850s or know how to use, maintain, or repair them. As a result, he says, guns contributed little to the homicide rate, especially among Whites, which was low everywhere, even in the South and on the frontier, where historians once assumed gun and murder went hand in hand. According to Bellesiles, these patterns changed dramatically after the Mexican War and especially after the Civil War, when gun ownership became widespread and cultural changes encouraged the use of handguns to command respect and resolve personal and political disputes. The result was an unprecedented wave of gun-related homicides that never truly abated. To this day, the United States has the highest homicide rate of any industrial democracy. Bellesile’s low estimates of gun ownership in early America conflict, however, with those of every historian who has previously studied the subject and has thus far proven irreproducible. Every homicide statistic he presents is either misleading or wrong.Given the influence of Kleck, Lott, Bellesiles and other partisan scholars on the debate over gun control and gun rights, we felt a need to pull together what social science historians have learned to date about the history of gun ownership and gun violence in America, and to consider what research methods and projects might increase our knowledge in the near future. ② The term "abate" in Line 8, Para. 2 possibly means().

A. vanish
B. terminate
C. fall
D. flourish
