There are those who consider it questionable that these defense-linked research projects will either improve our standard of living or do much to protect our diminishing resources. -->这句话只是说明了有人这么认为,但是不一定是事实。所以E的说法也只是部分人的观点,而不是事实。
C可以通过第一段说明: A recent study of important inventions made since the turn of the century reveals that more than half were the product of individual inventors working alone, independent of organized industrial research. While industrial laboratories contributed such important products as nylon and transistors, independent inventors developed air conditioning, the automatic transmission, the jet engine, the helicopter, insulin, and streptomycin. Still other inventions, such as stainless steel, television, silicones, and Plexiglas were developed through the combined efforts of individuals and laboratory teams. 即:individual inventors+ laboratory teams + combination = All research. 而more than half were the product of individual inventors working alone. 因此individual inventors > (laboratory teams + combination ) > laboratory teams |
