Directions: Read the following four passages. Answer the questions below each passage by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1.Passage One To paraphrase 18th-century statesman Edmund Burke, "all that is needed for the triumph of a misguided cause is that good people do nothing." One such cause now seeks to end biomedical research because of the theory that animals have rights ruling out their use in research. Scientists need to respond forcefully to animal rights advocates, whose arguments are confusing the public and thereby threatening advances in health knowledge and care. Leaders of the animal rights movement target biomedical research because it depends on public funding, and few people understand the process of health care research. Hearing allegations of cruelty to animals in research settings, many are perplexed that anyone would deliberately harm an animal. For example, a grandmotherly woman staffing an animal rights booth at a recent street fair was distributing a brochure that encouraged readers not to use anything that comes from of is tested in animals--no meat, no fur, no medicines. Asked if she opposed immunizations, she wanted to know if vaccines come from animal research. When assured that they do, she replied, "Then I would have to say yes." Asked what will happen when epidemics return, she said, "Don’t worry, scientists will find some way of using computers." Such well-meaning people just don’t understand. Scientists must communicate their message to the public in a compassionate, understandable way--in human terms, not in the language of molecular biology. We need to make clear the connection between animal research and a grandmother’s hip replacement, a father’s bypass operation, a baby’s vaccinations, and even a pet’s shots. To those who are unaware that animal research was needed to produce these treatments, as well as new treatments and vaccines, animal research seems wasteful at best and cruel at worst. Much can be done. Scientists could "adopt" middle school classes and present their own research. They should be quick to respond to letters to the editor, lest animal rights misinformation go unchallenged and acquire a deceptive appearance of truth. Research institutions could be opened to tours, to show that laboratory animals receive humane care. Finally, because the ultimate stakeholders are patients, the health research community should actively recruit to its cause not only well-known personalities such as Stephen Cooper, who has made courageous statements about the value of animal research, but all who receive medical treatment. If good people do nothing, there is a real possibility that an uninformed citizenry will extinguish the precious embers of medical progress. The example of the grandmotherly woman is used to show the public’s ______.

Directions: Read the following passage. For each numbered blank there are four choices marked A. B, C and D. Choose the best one and mark your answers on ANSWER SHEET 1. In the late 1960’s, many people in North America turned their attention to environmental problems, and new steel-and-glass skyscrapers were widely criticized. Ecologists pointing (21) that a cluster of tall buildings in a city often overburdens public transportation and parking lot (22) . Skyscrapers are also enormous (23) , and wasters, of electric power. In one recent year, the addition (24) 17 million square feet of skyscraper office space in New York City raised the (25) daily demand for electricity by 120,000 kilowatts-- enough to (26) the entire city of Albany for a day. Glass-wailed skyscraper can be especially (27) . The heat loss (or gain) through a wall of half-inch plate glass is more than ten times (28) through a typical masonry wall filled with insulation board. To lessen the strain (29) heating and air-conditioning equipment, (30) of skyscrapers have begun to use double-glazed panels of glass, and reflective glasses (31) with silver or gold mirror films that reduce (32) as well as heat gain. However, (33) skyscrapers raise the temperature of the surrounding air and (34) neighboring buildings. Skyscrapers put severe pressure on a city’s sanitation (35) , too. If fully occupied, the two World Trade Center towers in New York City would alone generate 2.25 million gallons of raw sewage each year--as (36) as a city the size of Stamford, Connecticut, which has a (37) of more than 109,000. Skyscrapers also (38) with television reception, block bird flyways, and obstruct air traffic. Still, people (39) to build skyscrapers for all the reasons that they have always built them--personal ambition and the (40) of owners to have the largest possible amount of rentable space.
