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
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

I'm going with c too.

I don;t think its D because the stimulus does not say anything about the effect of these amino acids on soil.

C

C: others of the closely related group of plants are also found to produce histidine in large quantities
OK. The arg says that histine allows the plant to grow in toxic soil. This would be strengthened if the others plants of the group produce also hisitine. If the the other plants of the group dont't produce H, then there is another factor explaining this phenomenon and that wd weaken.

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
NOK: there is no reference to Histine, which is the main point of the argument. Here, something else could make the soil suitable.

bit late but D it is.

C talks about the group that is irrelevant to hypothesis. Moreover,

'renders these metals chemically inert. Possibly, therefore, the herb’s high histidine production is what allows it to grow in metal-rich soils'

since metals are made chemically inert. this can be easily proved if we have plants that react to metals grow in presense of metals.

Sure:

"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 ______. " means that we are looking for a statement, that, if correct, strengthens the argument.

The original argument has 3 interesting statements:

1. the metals being discussed are toxic to most plants
2. histidine renders toxic metals inert
3. This is a hypothesis, and would be strengthened by some evidence...

Consider D. It shows that the above theory is correct because if the soil becomes suitable for plants to which the metals are toxic, then it means the toxicity is removed...all of this strengthens the theory that its the histidine in the soil rendering the metals inert....

Does this help?
