[求助]大全44-5题

Although much of this picture has been sustained by more recent research, it seems fundamentally wrong in one respect. Among the bacteria, there are organisms that are significantly different both from the cells of eukaryotes and from the true bacteria, and it now appears that there are three stems in the tree of life. New techniques for determining the molecular sequence of the RNA of organisms have produced evolutionary information about the degree to which organisms are related, the time since they diverged from a common ancestor, and the reconstruction of ancestral versions of genes. These techniques have strongly suggested that although the true bacteria indeed form a large coherent group, certain other bacteria, the archaebacteria，which are also prokaryotes and which resemble true bacteria, represent a distinct evolutionary branch that far antedates the common ancestor of all true bacteria.

5.     If the “new techniques” mentioned in line 31 were applied in studies of biological classifications other than bacteria, which of the following is most likely?

(A) Some of those classifications will have to be reevaluated.

(B) Many species of bacteria will be reclassified.

(C) It will be determined that there are four main categories of living things rather than three.

(D) It will be found that true bacteria are much older than eukaryotes.（A）

(E) It will be found that there is a common ancestor of the eukaryotes, archaebacteria, and true bacteria.

A和B都有相关bacteria大类需要调整导致2分法变3分法的意思。我觉得B明显更具体直接的靠近原文，比标准答案A好。请NN解。

我当时也选了B，但回头再看文章的时候，我发现自己犯了一个可笑的错误

此题题干中已经说了applied in studies of biological classifications other than bacteria,也就说问的是此技术应用在除bacteria之外的生物学划分领域，那显然B就不对了。

ps:想必楼主已经考完了，但是希望这个解释对后来的跟我们犯同样错误的xdjm有帮助。

首先是other than的意思, 我查了字典:

1.
            in addition to someone or something

2. except for someone or something

所以other than的意思有兩種, 應該視前後文判斷

這題答案(A)可以對應到這句 it now appears that there are three stems in the tree of life.

第二段開頭就說傳統的二分法有瑕疵, 應該有第三類classification

而(B)的species比較像是classification下的細微分類, species will be classified不是文章討論的重點

问题是：如果新技术应用于包括/除了细菌的生物分类研究，哪项最有可能？

回答应该是：生物分类将会发生……变化。而不是仅限于细菌分类吧？

问答对象一致。

new techniques指出：archaebacteria是早于true bacteria的另一个分支。如果new technique没有研究bacteria，那么人们就会默认所有的bacteria都来源于同一个祖先。而从第一段最后得知，bacteria的祖先比eukaryotes的共同祖先来得要晚。
仅此而已。
我觉得A选项刚好针对的是new techniques被应用到bacteria上的情况，这恰恰与题干问的情况相反。

旧题重拿出来讨论哈，这个我也错了，同意这个解释
但现在看A和B选项的措词：一个说有些分类会被reevaluated，会被重新评估，这个说法很研谨
而B说许多物种需要被重分类，如果用了这个新科技就真的会导致许多被重分类吗？我觉得说得有点过了。所以相比还是A项好
