As an example of how this worked, when facial tissues (面巾纸) were first put on the market in 1924, they were made in limited quantities and sold at 65 cents per box of 200. People like these facial tissues immediately and began asking for them when they went into different stores. Because there was such a demand for the product, manufacturers began making tissues in larger and larger quantities. Because the manufacturers were making tissues in greater quantities, their production costs were lowered, so that the price of tissues went down. (80) In the meanwhile, the quality of facial tissues was constantly improving, because more manufacturers went into the business of making tissues, and each manufacturer strove to make his product better than his competitors’. Today, instead of costing 65 cents, a box of 200 tissues costs around one—third of that price, and they are both softer and stronger.
When people are free to compete—when they are free to make more things and make them better—everyone benefits.
In regard to the production of goods in greater quantities, the author states that ______.
A．the price of the goods should drop
B．the quality of the goods should improve
C．the price and the quality should both rise
D．the quality and the price should both drop

This materialistic outlook has seriously influenced education. Fewer and fewer young people these days acquire knowledge only for its own sake. Every course of studies must lead somewhere: i.e. to a bigger wage pocket. The demand for skilled personnel far exceeds the supply and big companies compete with each other to recruit students before they have completed their studies. Tempting salaries and “fringe benefits” are offered to them. Recruiting tactics of this kind of have led to the “brain drain”, the process by which highly skilled people offer their services to the higher bidder. The wealthier nations deprive their poorer neighbors of their most able citizens. While Mammon is worshipped as never before, the rich get richer and the poor, poorer.
Will mankind continue to live longer and have a higher quality of life？ In large measure the answer depends on technology and our ability to use it wisely. If we keep making progress as we have over the past fifty years, the answer is definitely yes. (82) The advancement of technology depends upon research and development, and the latest statistics show that the United States is continuing to pump billions of dollars annually into such efforts. So while we are running out of some scarce resources, we may well find technological substitutes for many of them through our research programs.
Therefore, in the final analysis the three major factors of production (land, labor, capital) are all influenced by technology. When we need new skills or techniques in machinery, people will start developing new technology to meet these needs. As equipment proves to be slow or inefficient, new machines will be invented. Technology responds to our needs in helping us maintain our standard of living.
