The long years of food shortage in this country have suddenly given way to apparent abundance. Stores and shops are choked with food. Rationing is virtually suspended, and overseas suppliers have been asked to hold back deliveries. Yet, instead of joy, there is widespread uneasiness and confusion. Why do food prices keep on rising, when there seems to be so much more food about Is the abundance only temporary, or has it come to stay Does it mean that we need to think less now about producing more food at home No one knows what to expect. The recent growth of export surpluses on the world food market has certainly been unexpectedly great, partly because a strange sequence of two successful grain harvests in North America is now being followed by a third. Most of Britain’s overseas suppliers of meat, too, are offering more this year and home production has also raised. But the effect of all this on the food situation in this country has been made worse by simultaneous rise in food prices, due chiefly to the gradual cutting down of government support for food. The shops are over- stocked with food not only because there is more food available but also because people, frightened by high prices, are buying less of it. Moreover, the rise in domestic prices has come at a time when world prices have begun to fall with the result that imported food, with the exception of grain, is often cheaper than the home- produced variety. And now grain prices, too, are falling. Consumers are beginning to ask why they should not be enabled to benefit from this trend. The significance of these developments is not lost on farmers. The older generations have seen it all happen before. Despite the present price and market guarantees, farmers fear they are about to be squeezed between cheap food imports and a shrinking home market. Present production is running at 51 percent above pre-war levels, and the government has called for an expansion to 60 percent by 1956; but repeated ministerial advice is carrying little weight and the expansion program is not working very well. Why didn’t the government’s expansion program work very well

A. Because the farmers were uncertain about the benefits of expanding production.
Because the farmers were uncertain about the financial support the government guaranteed.
C. Because the farmers were uncertain whether foreign markets could be found for their product.
D. Because the older generation of farmers were strongly against the program.

Revolutionary innovation is now occurring in all scientific and technological fields. This wave of unprecedented change is driven primarily by advances in information technology, but it is much larger in scope. We are not dealing simply with an Information Revolution but with a Technology Revolution. To anticipate developments in this field, the George Washington University Forecast of Emerging Technologies was launched at the start of the 1990s. We have now completed four rounds of our Delphi survey — in 1990, 1992, 1994, and 1996 — giving us a wealth of data and experience. We now can offer a reasonably clear picture of what can be expected to happen in technology over the next three decades. Time horizons play a crucial role in forecasting technology. Forecasts of the next five to ten years are often so predictable that they fall into the realm of market research, while those more than 30 or 40 years away are mostly speculation. This leaves a 10- to 20-year window in which to make useful forecasts. It is this time frame that our Forecast addresses. The Forecast uses diverse methods, including environmental scanning, trend analysis, Delphi surveys, and model building. Environmental scanning is used to identify emerging technologies. Trend analysis guides the selection of the most important technologies for further study, and a modified Delphi survey is used to obtain forecasts. Instead of using the traditional Delphi method of providing respondents with immediate feed- back and requesting additional estimates in order to arrive at a consensus, we conduct another survey after an additional time period of about two years. Finally, the results are portrayed in time periods to build models of unfolding technological change. By using multiple methods instead of relying on a single approach, the Forecast can produce more reliable, useful estimates. For our latest survey conducted in 1996, we selected 85 emerging technologies representing the most crucial advances that can be foreseen. We then submitted the list of technologies to our panel of futurists for their judgments as to when (or if) each technological development would enter the mainstream, the probability that it would happen, and the estimated size of the economic market for it. In short, we sought a forecast as to when each emerging technology will have actually "emerged". Various research methods are employed in order to______.

A. reach a consensus of opinions
B. provide immediate feedback
C. increase the accuracy of predictions
D. select crucial technologies
