In the years since the city of London imposed strict air-pollution regulations on local industry, the number of bird species seen in and around London has increased dramatically. Similar air-pollution rules should be imposed in other major cities.
Each of the following is an assumption made in the argument above EXCEPT:
(A) In most major cities, air-pollution problems are caused almost entirely by local industry.
(B) Air-pollution regulations on industry have a significant impact on the quality of the air.
(C) The air-pollution problems of other major cities are basically similar to those once suffered by London.
(D) An increase in the number of bird species in and around a city is desirable.
(E) The increased sightings of bird species in and around London reflect an actual increase in the number of species in the area.
答案选D， 我选的是A， 觉得还是A比较合理。
In 1986, the city of Los Diablos had 20 days on which air pollution reached unhealthful amounts and a smog alert was put into effect. In early 1987, new air pollution control measures were enacted, but the city had smog alerts on 31 days that year and on 39 days the following year. In 1989, however, the number of smog alerts in Los Diablos dropped to sixteen. The main air pollutants in Los Diablos are ozone and carbon monoxide, and since 1986 the levels of both have been monitored by gas spectrography.
Which of the following statements, assuming that each is true, would be LEAST helpful in explaining the air pollution levels in Los Diablos between 1986 and 1989?
(A) The 1987 air pollution control measures enacted in Los Diablos were put into effect in November of 1988.
(B) In December of 1988 a new and far more accurate gas spectrometer was invented.
(C) In February of 1989, the Pollution Control Board of Los Diablos revised the scale used to determine the amount of air pollution considered unhealthful.
(D) In 1988 the mayor of Los Diablos was found to have accepted large campaign donations from local industries and to have exempted those same industries from air pollution control measures.
(E) Excess ozone and carbon monoxide require a minimum of two years to break down naturally in the atmosphere above a given area.
答案是B 可是觉得A也least， 因为他不能说明1989年的
Studio executives carefully examine how a film performs on its opening weekend in order to determine whether-and how-to invest more in that film, Many decisions, such as increasing the number of screens that show the film' and··expanding the marketing campaign, are best made after reactions can be gathered frornaudiences who actually purchased tickets. Therefore, to maximize returns on their marketing investments, studios should initially release all their films on a small ,number of screens and with a limited advertising campaign. The plan to maximize returns by initially releasing films on only a small number of screens and limiting advertising depends upon which of the following assumptions?
(A) Large marketing investments made before the opening weekend never eventually yield greaterproflts than small initial marketing investments.
(B) New advertising techniques, such as Web-baSed viral marketing, have not substantially reduced the average marketing costs for films.
(C) A film's prior performance in noncommercial settings, such as festivals, is not well correlated with how the general public tends to react to that film.
(D) Across the movie industry, marketing investments do not influence the eventual financial returns of films in predictable ways.
(E) How a film performs during its opening weekend is a strong indicator of the film's financial performance over its lifetime.
