You're right that it's not easy to cut out a middleman here. We have to analyze the whole thing and see which parts are modifying which other parts.

The main subject of the sentence is Marconi. Let's start with a simple sentence and build up:

Marconi conceived of the radio.

Here, Marconi is the subject and radio is the object.

Marconi conceived of the radio as a tool.

Here, we have added an object complement. The portion "as a tool" describes how Marconi conceived of the radio.

Marconi conceived of the radio as a tool for private conversation.

Now we have modified the object complement to add detail. What kind of tool was the radio supposed to be? A tool for private conversation.

Marconi conceived of the radio as a tool for private conversation that could substitute for the telephone.

We have added a helping verb to the object complement. What could substitute for the telephone? "A tool for private conversation." Of course, since the tool in question is the radio, we could say that this also refers to the radio, but structurally it is tacked onto the part about the tool.

At this point, we can simplify the structure of the sentence down to "X conceived of Y as Z."
X=Marconi
Y=the radio
Z=a tool for private conversation that could substitute for the telephone.

So after all that, perhaps you can see why a semicolon shows up. We already have a rather full sentence! To retain clarity, the author essentially begins a new sentence to express the actual fate of the radio. Although we might follow the meaning if the sentence went on with "but" (" . . . telephone, but it has become . . ."), the meaning of "it" at this point might be a bit unclear. By starting a new independent clause, we are removed from all the mucky modifiers and complements, and can return back to the direct object--radio.

这题很难，我不太同意用跳跃修饰的讲法去考虑这个问题，因为也有很多种情况下n1+prep+n2,which也就是n2的，从句意的角度讲我们说话中会用到这样的修饰方法，所以我觉得跳跃修饰只是在我们无法解题是用来解释一个相对较正确选项的手段而不是解题思路。


不考虑conceive of...as的话，which无论就近修饰telephone或者conversation或者跳过插入语修饰conversation或者telephone都是和句意不符合的，可以排除BD


E的other than what it is既无法代替instead/but的转折意思，本身放在句中很混乱的结构，前面是一个完整句子，other than what it is在这里是连词作用还是插入语呢？所以排除


A的话a tool for...在这里是有修饰歧义的，我本来也选择了A，我的理由是BCDE和A的意思不符合，因为我以为a tool for private conversation修饰的是telephone！！虽然可以不认为它是同位语是独立主格，但是读句子时就近修饰的概念是不会变得，所以就产生了语义歧义，这是比指代不清更严重的错误。事实上如果你去看老外对此题的解释也有很多人在问为什么A错了，后面几句都把句意改变了这样的问题


但是解题时候这么思考一分钟甚至一分半可能根本不够，动词优于名词以及conceive of ... as ...的结构应该还是王道啊

C的that的确也是有歧义可以就近指代conversation的，但是读到substitute以及for telephone的时候马上会想到这是指代在前面的内容radio或者tool。我觉得比较好的方法是把C改成：M conceived of the radio that could substitute for the telephone as a tool for private conversation; instead...

但要光因为动词优于名词的原则要排除A真是要花很大决心的，因为M's conception of the radio并没有错，而且你说的对，全句看上去很对称，如果a tool for private...修饰telephone, a tool for communication修饰radio

我觉得A 可对称了。

接受 Silent7706 关于A项 it 的指代, 指代 M's conception；
接受 Silent7706 关于C项 that 的修饰， a tool for private conversation

............
再看一遍，觉得C项: M conceived of the radio as a tool for private conversation that could substitute for the telephone.
是跳跃指代，指代the radio.

ABE选项中的 a tool for private conversation有没有可能修饰telephone呢 求解

li3360065

我觉得谈论句意永远比用什么结构 什么句型 什么套路 要重要。
GMAT 我觉得做语法 先用简单语法排除，时态，单复数等等，然后是否make sense  最后再排除 akward ,wordy 选项。

A 中 conception 不能是 telephone 的substitute,而是radio.
B a tool for private conversation修饰出错了，主句的意思是想修饰radio, But 这个转折太突兀。which 错误的修饰了conversation.
C correct.
D 归类于idiom,conceive of xxx as 而不是 to be .which修饰错误。
E to be 直接秒杀

其实A选项最大的问题是:这句话的主语是M's conception,于是分号后面的it指代的一定是这个主语，所以错了

定语从句的that不是一定要紧跟在被修饰的对象后面的吗？只有which才可以跳跃介词短语修饰的吗？我就是按 ...

內文說可以跳躍指代，可是附件裡面說S+V+O, which 指代 S一定錯

106. Originallydeveloped for detecting air pollutants, a technique called proton-induced X-rayemission, which can quickly analyze the chemical elements in almost anysubstance without destroying it, is finding uses in medicine, archaeology, and criminology.

紅色句子可以還原成 a technique that is called proton-induced X-ray emission
省略 that is 作為分詞片語 修飾 technique
可是後面接上, which 是對 X-ray emission修飾? 還是technique修飾?
抓到最近的that 子句應該會是對 X-ray emission
我好奇問一下 這邊我有點不太明白 ,which 可以做跳躍 又不指代S+V+O的S

我不是完全同意li3360065对B选项的解释

A错在Conception...was as a substitute...原句是说radio是substitute而非conception

B中的modifier: a tool for private conversation本身是没问题的，修饰的是telephone；这个选项错在but which，因为有了but，表明了是parallelism，所以 which is... 作为modifier与a tool for private conversation平行，修饰的是telephone，句意出错（因为which is... 这个modifier应该修饰radio）

B中另一个更明显的错误是parallel的两个modifier不是真正的对称，一个是appositive，另一个是which引导的

D和E最实用的判断方法就是conceive of A as B这个idiom；当然这两个选项中还有其他错误，但是做题时没那么多时间进行那些分析

BAT, BABYMM, DUKB都是经典啊

西卜儿的兔子

C选项中的that的疑问都解了，但是关于后面的instead,it has become的it,OG上说的很清楚地是指代radio，但是it之前还有不少其他名词，像tool,telephone什么的，这样不是It的指代就不清楚了吗？求哪位大神指点！谢谢！
