We have only to look behind us to get some sense of what may lie ahead. No one looking ahead 20 years possibly could have foreseen the ways in which a single invention, the chip, would transform. our world thanks to its applications in personal computers, digital communications and factory robots. Tomorrow's achievements in biotechnology, artificial intelligence or even some still unimagined technology could produce a similar wave of dramatic changes. But one thing is certain: information and knowledge will become even more vital, and the people who possess it, whether they work in manufacturing or services, will have the advantage and produce the wealth. Computer knowledge will become as basic a requirement as the ability to read and write. The ability to solve problems by applying information instead of performing routine tasks will be valued above all else. If you cast your mind ahead 10 years, information services will be predominant. It will be the way you do your job.
A characteristic of the information age is that __________

We invited staff volunteers who had a strong liking for either Coca-Cola Classic (传统型) or Pepsi, Diet(低糖)Coke, or Diet Pepsi. These were people who thought they'd have no trouble telling their brand from the other brand.
We eventually located 19 regular cola drinkers and 27 diet cola drinkers. (80) Then we fed them four unidentified samples of cola one at a time, regular colas for the one group, diet versions for the other. We asked them to tell us whether each sample was Coke or Pepsi; then we analyzed the r6cords statistically to compare the participants' choices with what mere guess-work could have accomplished.
Getting all four samples right was a tough test, but not too tough, we thought, for people who believed they could recognize their brand. In the end, only 7 out of 19 regular cola drinkers correctly identified their brand of choice in all four trials. The diet-cola drinkers did a little worse--only 7 of 27 identified all four samples correctly.
While both groups did better than chance would predict, nearly half the participants in each group made the wrong choice two or more times. Two people got all four samples wrong. Overall, half the participants did about as well on the last round of tasting as on the first, so fatigue, or taste burnout, was not a factor. Our preference test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price.
According to the passage the preference test was conducted in order to ______.
