问题     Many of the modern world’ s most famous discoveries and inventions were not made by scientists, but by amateur inventors. Often these inventors had such unusual ideas that they were often laughed at. But people like these inventions. Working on their own, these inventors gave us many of the things we use every day.
    Clarence Birdseye, who invented frozen foods, was both a successful inventor and a good businessman. But it took him years to overcome the biggest problem of successful inventions—convincing people to try something new and different. Birdseye first tried to freeze fish. After years of experiments, he started Birdseye Seafoods, Inc. Even though the experiments were successful, people didn’ t believe that frozen fish could possibly be good. The company was losing money and soon it went bankrupt. Birdseye did not lose heart. It took a long time, but people finally accepted frozen food. By the end of his life, Birdseye, who was a completely self-taught inventor, sold his patents for a total of 22 million dollars.
    Few inventors were as successful as Birdseye. Some did not realize the importance of their discoveries. The son of the inventor of Coca-Cola sold the recipe for $ 2 ,300. Today the product is worth billions of dollars. In 1853, Karl Gerhardt invented aspirin but he didn’t know what to do with it. Fifty years after his invention, a German company discovered that was a painkiller and has made millions selling it. Edwin Armstrong invented FM radio, but he spent his life trying to protect his invention. Competitors stole his patents, and companies cheated him out of money. Finally, he became so disappointed with his failures that he ended his life by jumping out of a window.
    Most great inventors, like Gerhardt and Armstrong, made little or nothing from their inventions. The first person with a new idea may get attention, but he also gets the problem of an untried idea. In business, it is sometimes better to be second.
The writer of the selection implies that most inventors ________.

选项 A、are from wealthy families
B、are great scientists
C、are not good businessmen
D、do not get attention at all

答案C

解析 推理判断题。根据文中最后一句,在生意场上,通常是利用别人的发明更有利可图。由此可见,发明家本人往往不能从发明中获利。故选C。
