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 ______.

如今JJ里面GWD28-Q28题,逻辑一题,哪个答案更好?

本月有人考到这个逻辑题目,哪个答案更好呀?C?,E?

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 ______.

 

 

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

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

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

  4. 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

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

別帖我已經把選E的理由講出來拉

http://forum.chasedream.com/dispbbs.asp?boardID=22&ID=290071&star=2&page=  20F

原題有這一句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. 

選C不就自打嘴巴便成否定了

在強調一次...CR裡面採用OTHER /OTHERS開頭出現正確答案的機會不高...

這題選C變成否定

LS的对题目第一句话理解有偏差吧,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.  这种草药只是能在重金属土壤环境中茁壮生长的一种,还有其他

文中講的植物xx是相近類別植物YY中的一種....然後xx有histidine

....這裡沒說YY有沒histidine....

然後選項C說~YY也有histidine...那不就表是..xx有histidine不能表示他抗重金屬...

變成否定...那就錯拉..怎可能選C...

E是正確的我很肯定~~~

好拉不講了~~解釋半天~~

累了

以下是引用peter27在2007-11-25 21:51:00的发言:

晕啦?只有C和E值得讨论。偶支持E,你呢?
