28. GWD28-Q28:

Which of the following most logically completes the argument?

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 herb have discovered that it produces large amounts of histidine, an amino acid that, in test-tube solutions, renders these metals chemically inert.  Possibly, therefore, the herb’s high histidine production is what allows it to grow in metal-rich soils, a hypothesis that would gain support if ___E__.

A.    histidine is found in all parts of the plant—roots, stem, leaves, and flowers

B.    the herb’s high level of histidine production is found to be associated with an unusually low level of production of other amino acids

C.    others of the closely related group of plants are also found to produce histidine in large quantities

D.    cultivation of the herb in soil with high concentrations of the metals will, over an extended period, make the soil suitable for plants to which the metals are toxic

E.     the concentration of histidine in the growing herb declines as the plant approaches maturity

 请问大家，为什么选C呢？

力挺E. GWD的答案是C

应该是C。答案正确。

E起不了加强的作用，而C能加强。

GWD20套里的,我也错了

C确实加强

说明不是因为因为种在这里才导致高含量的.
