PART IV READING COMPREHENSION
　　In this section there are five passages followed by fifteen questions or unfinished statements, each with four suggested answer marked A, B, C and D.    Choose the one that you think is the correct answer.
　　TEXT A The worldwide consumption of bakery products is increasing. Many populations that formerly relied solely on rice or coarser grains as their main source of carbohydrates show a preference for compounded bakery products as new industry and increased incomes make them more widely accessible. Japan is an outstanding example of countries following this trend. The United States has shown a steady downward trend in per capita consumption of cereal-based foods for many years, and the consumption of sweet bakery foods, such as cakes or pastry, has been increasingly displacing bread consumption. Probably 95% of the white bread sold in the United States is enriched with thiamin, niacin, riboflavin, and iron, and about 30% of the 50 states have laws requiring white bread enrichment. Formerly, calcium and vitamin D were frequently added to enriched bread, but lack of consumer demand and questionable nutritional benefit led to gradual phasing out of these enrichments. India has attempted to encourage consumption of protein-enriched bread, with some success. Except for research projects, little has been done in other countries, however. In areas where bakery products comprise a large proportion of the diet, they could provide an ideal vehicle for nutritional supplementation. Then need for better quality protein in the daily diet occurs mostly in the developing countries, where carbohydrate foods —— usually cereals —— are the basic components of the diet and therefore the logical protein carriers.
