题目内容
A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals that are toxic to most other plants. Agronomists studying the growth of this herb have discovered that it produces large amounts of histidine, an amino acid that, in test-tube solutions, renders these metals chemically inert. Hence, the herb`s high histidine production must be the key feature that allows it to grow in metal-rich soils.

In evaluating the argument, it would be most important to determine which of the following?
  • AWhether the herb can thrive in soil that does not have high concentrations of the toxic metals 分析该选项
  • BWhether others of the closely related group of plants also produce histidine in large quantities 分析该选项
  • CWhether the herb`s high level of histidine production is associated with an unusually low level of production of some other amino acid 分析该选项
  • DWhether growing the herb in soil with high concentrations of the metals will, over time, reduce their concentrations in the soil 分析该选项
  • EWhether the concentration of histidine in the growing herb declines as the plant approaches maturity 分析该选项
