[单项选择]Unlike the scientist, the engineer is not free to select the problem which interests him；he must solve the problems as they arise, and his solutions must satisfy conflicting requirements. Typically, the engineering solution to most problems must take into account many factors.
To the engineer, efficiency means output divided by input. His job is to secure a maximum output for a given input or to secure a given output with a minimum input. The ratio may be expressed in terms of energy, materials, money, time, or man. Most commonly the denominator (分母) is money；in fact, most engineering problems are answered ultimately in dollars and cents.
The emphasis on efficiency leads to the large, complex operations which are characteristic of engineering.

A. He must choose the long-term solution to a problem.
B. He may study the problem he has an interest in.
C. He can avoid the conflict between work and pleasure.
D. He should be familiar with some engineering problems.

Passage One

A scientist who does research in economic psychology and who wants to predict the way in which consumers will spend their money must study consumer behavior. He must obtain data both on the resources of consumers and on the motives that tend to encourage or discourage money spending.
If an economist were asked which of three groups borrow most -- people with rising incomes, stable incomes, or declining incomes -- he would probably answer: those with declining incomes. Actually, in the years 1947 -- 1950, the answer was: people with rising incomes. people with declining incomes were next and people with stable incomes borrowed the least. This shows us that traditional assumptions about earning and spending are not always reliable. Another traditional assumption is that if people who have money expect prices to go up, they wil
A. rely on traditional assumptions about earning and spending
B. try to encourage or discourage consumers to spend money
C. carry out investigations on consumer behavior and obtain data on consumers’ incomes and money spending motives
D. do researches in consumer psychology in a laboratory

Mad Scientist Stereotype Outdated

Do people still imagine a physicist as a bearded man in glasses or has the image of the mad scientist changed The Institute of Physics set out to find out whether the stereotype of a physics "boffin" (科学家) still exists by conducting a survey on shoppers in London. The people were asked to identify the physicist from a photograph of a line-up of possible suspects. 98 percent of those asked got it wrong. The majority of people picked a white male of around 60, wearing glasses and with a white beard.
While this stereotype may have been the image of an average physicist fifty years ago, the reality is now very different. Since 1960 the number of young women entering physics has doubled and the average age of a physicist is now 31.
The stereotype of the absent-minded scientist has lasted a long time because the media and Hollywood help promote the image of men in white lab coats with glasses sitting
A. Right
B. Wrong
C. Not mentioned
