According to the passage, the five well-known plant hormones are not useful in controlling the growth of crops because______ [br] The passage suggests that, unlike the pleiotropic hormones, oligosaccharins could be used effectively to______
选项
A、trace the passage of chemicals through the walls of cells
B、pinpoint functions of other plant hormones
C、artificially control specific aspects of the development of crops
D、alter the complement of genes in the cells of plants
E、alter the effects of the five major hormones on plant development
答案
C
解析
The best answer is C. Lines 16-18 state that because each pleiotropic hormone has so many different effects on a plant, pleiotropic hormones “are not very useful in artificially controlling the growth of crops” (lines 17-18). In contrast, the passage indicates that oligosaccharins have specific effects on the growth and development of plants. Thus, in comparison to the pleiotropic hormones, oligosaccharins could potentially be effective in artificially controlling specific aspects of crop development. Choices A, B, D, and E can be eliminated because they describe functions that are not attributed in the passage either to the pleiotropic hormones or to oligosaccharins.
