Yet, he consider   1   (him) a farmer because he continually works the land in his research. Indeed, his slim   2   strong body is just like that of millions of Chinese farmers,   3   whom he has devoted his life. Yuan Longping was born in 1930 in Beijing. His parents wanted him   4   (pursue) a career in science or medicine. However,   5   concerned him most was that farmers often had poor harvests and sometimes even had a serious   6   (short) of food to eat.

Today,   19   is estimated that about 60 percent of domestic rice   20   (consume) in China is comprised of crops   21   (generate) from Yuan’s hybrid strains, and his strains have allowed China’s farmers to produce around 200 million tons of rice per year, Yuan’s   22
