不太確定 Huang大大要闡述什麼樣的意思?
不過點到題目中的主要邏輯思維點…
提到:"答案C的others....不就都是在高濃度有毒金屬土壤裡生長茂盛的植物嗎?"
正確
所以如果能確定那些其它植物, 生長於高濃度有毒金屬土壤的那些, 都有produce histidine,那就大大的支持(C)嚕!
由於題目只說到A certain cultivated herb 只是其中一個group,如果又能確定其它的都能produce histidine,就更加的確定produce histidine是生長於高濃度有毒金屬土壤的重要關鍵!!
題目:A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals
C: others of the closely related group of plants are also found to produce histidine in large quantities
one of a group 對照 others of the closely related group ( one ....others)
以上參考○魯!!
