题目分析：
略。
选项分析：
A选项：本选项具有语法错误。未划线部分的whereas the honeybee’s stinger is heavily barbed and cannot be retracted from the skin是由连词whereas引导的状语从句，划线部分中because the yellow jacket has a comparatively smooth stinger是原因状语从句。在语法上，当一个主句拥有两个状语从句时，应该用并列连词and连接，不能直接扔在主句身前，例如：
(1) Because I was hungry and because I wanted to have a rest, I stepped into that restaurant.
(2) ** Because I was hungry, because I wanted to have a rest, I stepped into that restaurant.
句(2)是错误的。
B选项：代词them是复数代词，只能指代复数名词，但是本题中的yellow jacket是单数名词。另外，并列连词and连接的两句在语法上虽然没有问题，但是补出and身后省略的主语则有：
the comparative smoothness of the yellow jacket’s stinger used again.
显然地，use的发出者不能是smoothness。
C选项：Correct. 本选项在语法和逻辑上均是正确的。
D选项：介词短语in comparison和whereas均表示对比，因此in comparison赘余。
E选项：in comparison赘余错误同选项(D)。
in comparison和whereas均表示对比，因此in comparison赘余。
1. A选项：本选项具有语法错误。未划线部分的whereas the honeybee’s stinger is heavily barbed and cannot be retracted from the skin是由连词whereas引导的状语从句，划线部分中because the yell
ow jacket has a comparatively smooth stinger是原因状语从句。在语法上，当一个主句拥有两个状语从句时，应该用并列连词and连接，不能直接扔在主句身前
2. B: the comparative smoothness of the yellow jacket’s stinger used again.
显然地，use的发出者不能是smoothness。
3. 介词短语in comparison和whereas均表示对比，因此in comparison赘余。
Whereas 和 in comparison 重复
介词短语in comparison和whereas均表示对比，因此in comparison赘余。
B 主谓不一致 yellow jacket 单数
m
介词短语in comparison和whereas均表示对比，因此in comparison赘余。
B选项的yellow jacket's 是所有格，所有格不是名词，解析里面提出的yellow jacket是单数名词是不是有些不合适额
A，两个状语从句 whereas ... because ... ❌ ，需要连词

A：it指代不清，乱
B：them找不到指代对象
C：因为黄蜂的针顺滑，所以可以拔出来
D：in comparison赘余
E：同上
DE redundancy是一方面，我觉得D 后面那句， and thus able to这里省略的是主语stinger ，明显stinger是不能用able to 的。只有有主观生物才可以able or unable
E 是主语主语和从句主语不一样了，不能对比
做题的时候在BC里纠结了一下，其实B错的还是很明显的
把and之后的部分对应到前面发现没有主语可以连接 jacket's stinger并不能can use it...
至于DE：Ron：
"Whereas" already implies that you're drawing a contrast between two different situations. So, "whereas" + "in comparison" = redundant.
in comparison 冗余
是两种stinger之间的比较，排除ABE。赘余排除D。
选项A具有两个状语从句，需并列
选项B的them指代也有问题，the comparative smoothness of 结构复杂 use的发出者是smoothness也有问题
DE 的in comparison 坠余错误
