问题     Major companies are already in pursuit of commercial applications of the new biology. They dream of placing enzymes in the automobile to monitor exhaust and send data on pollution to a microprocessor that will then adjust the engine. They speak of what the New York Times calls "metal-hungry microbes that might be used to mine valuable trace metals from ocean water." They have already demanded and won the right to patent new life forms.
    Nervous critics, including many scientists, worry that there is corporate, national, international, and inter-scientific rivalry in the entire biotechnological field. They create images not of oil spills, but of "microbe spills" that could spread disease and destroy entire populations. The creation and accidental release of extremely poisonous microbes, however, is only one cause for alarm. Completely rational and respectable scientists are talking about possibilities that stagger the imagination.
    Should we breed people with cow-like stomachs so they can digest grass and hay, thereby relieving the food problem by modifying us to eat lower down on the food chain? Should we biologically alter workers to fit the job requirement, for example, creating pilots with faster reaction times or assembly-line workers designed to do our monotonous work for us? Should we attempt to eliminate "inferior" people and breed a "super-race"? (Hitler tried this, but without the genetic weaponry that may soon issue from our laboratories.) Should we produce soldiers to do our fighting? Should we use genetic forecasting to pre-eliminate "unfit" babies? Should we grow reserve organs for ourselves, each of us having, as it were, a "savings bank" full of spare kidney, livers, or hands?
    Wild as these notions may sound, everyone has its advocates (and opposers) in the scientific community as well as its striking commercial applications. As two critics of genetic engineering, Jeremy Rifkin and Ted Howard, state in their book Who Should Play God? "Broad scale genetic engineering will probably be introduced to America much the same way as assembly lines, automobiles, vaccines, computers and all the other technologies. As each new genetic advance becomes commercially practical, a new consumer need will be exploited and a market for the new technology will be created."
What does Jeremy Rifkin and Ted Howard’s statement imply?

选项 A、The commercial applications of genetic engineering are inevitable.
B、America will depend on other countries for biological progress.
C、Americans are proud of their computers, automobiles and genetic technologies.
D、The potential application of each new genetic advance should be controlled.

答案A

解析 推理判断题。最后一段最后两句提到,杰里米.里夫金和特德.霍华德在书中说,大规模的基因工程将会像流水线、汽车、疫苗、电脑等科技一样引进美国;随着基因发展在商业上变得实用,这种技术将创造新的消费需求和新的市场。由此可推测,他们认为基因工程的商业化应用不可避免。
