這題答案個人覺得沒有爭議，是C。
※ 引述《yuanz (rock your body)》之銘言：
: 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 ______.
: (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
文章第一句就說了「同類的植物都能抗毒」
所以其中一種產histidine，要支持就是說其他能抗毒（同類）的植物都是因為histidine
這叫做舉更多例子加強連結。
: (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
結論說的是「這種植物能活下去的原因」，跟其他原本受毒的植物能不能活下去無關
: (E)the concentration of histidine in the growing herb declines as the plant
: approaches maturity
成長過程中histidine的量變多或變少，跟大量的histidne殺毒與否沒有直接關係
