OA is provided

Why not D?

The modifiers CANNOT modify across "and", "but" etc.
The modifier in the status quo is "but on hearing". So it will modify the clause that comes just after this modifier WHEREAS without "but" in modifier, it seems that "on hearing" can modify either side of it, creating ambiguity.
B implies that Galileo WAS the inventer because the other device was being made; lacks the subject; is a run on.
C and D have modifier ambiguity.; D lacks the subject.
E changes the meaning by implying that the other device was still being made WHEREAS the original intent says that the other device had already been made.

Hi Jaiidex,

In my opinion, the difference between the two for GMAT purposes at least is not worth worrying about. There may be a difference in style, but that's it.

You've correctly ascertained that there is no grammatical issue with either, so this should suffice...

Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he quickly built his own device from an organ pipe and spectacle lenses.

A. Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he Best choice - all verbs work together

B. Galileo had not invented the telescope, but when he heard, in 1609, of such an optical instrument having been made, Wrong - second clause is a fragment; no need for past participle + "invented" because the sentence is clear without it.

C. Galileo, even though he had not invented the telescope, on hearing, in 1609, that such an optical instrument had been made, he Wrong - two subjects in the sentence; part participle + "invented" is not needed because there is no need to distinguish the past; wordy and awkward.

D. Even though Galileo did not invent the telescope, on hearing, in 1609, that such an optical instrument had been made, Wrong - sentence is a fragment without a subject.

E. Even though Galileo did not invent the telescope, but when he heard, 1609, of such an optical instrument being made, he Wrong - multiple modifiers make the sentence wordy; "being made" indicates a progressive tense, altering the meaning of the sentence.

IMO A

can somebody plz explain the difference between "on hearing that" and "when he heard of"? I think both is correct but it is a difference in the sentences and I was not able to understand the different meanings of it


"on hearing" is an prepositional phrase, and the object of the preposition is the gerund "hearing." Thus, "hearing" must be a noun which implies the act of hearing.

"when he heard of" is adverbial clause, and "heard" is describes the noun - i.e. what the subject does.

In general, "on hearing" is wordy and imprecise because other phrases are likely to follow. After all, it's natural that someone creates a sentence from either a series of prepositional phrases or structured with relative pronouns. Good writers can mix both together. Only if the answer choice permits, choose the less wordy one.

I hope this helps.

First split:- Modification of last clause (quickly....lenses)
Since it modifies Galileo we need to plug "he" before "quickly".
Eliminate -->B, D

Second split --> past perfect (had been) vs continuous (being)
This is the case for past perfect
Eliminate --> E

Third Split --> Use of Even though and also intended meaning of the sentence
Even though is used to show paradox. Also if you remove the modifiers in C it gives an impression that on hearing about the creation of optical instrument created his own which is not the intended meaning.
Eliminate --> C

Answer --> A

"but" is a co-ordinating conjunction. So "but" should introduce an independent clause. So my question is:

but on hearing, in 1609, that such an optical instrument had been made, he quickly built
Then the entire portion marked in bold acts as a modifier for the subject "he" and the verb "built". Is that it?

"But" does not necessarily join two independent clauses. Like "and", it can be used to join nouns, verbs, participles, etc.

Not John, but Jack is responsible for the accident. (2 nouns joined)
I will not sleep but work during this night. (2 verbs are joined)

Nonetheless in option A two independent clauses are joined:
Galileo did not invent, but he quickly built.

("Eliminate middlemen" as Manhattan SC guide suggests.)

"on hearing......had been made" is a modifier.

A. Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he

B. Galileo had not invented the telescope, but when he heard, in 1609, of such an optical instrument having been made,

D. Even though Galileo did not invent the telescope, on hearing, in 1609, that such an optical instrument had been made,

E. Even though Galileo did not invent the telescope, but when he heard, 1609, of such an optical instrument being made, he

Past perfect wrong in "Galileo had not invented the telescope". this is a simple fact that Galileo didn't invent the telescope.
Between A & E :

E : "Even though" introduce a paradox in the sentence :

Even though I am not well, I am working 24/7.

No need of even though here

Galileo did not invent X, but on hearing that (someone did invent X), he built his own device.

I did not invent the GMAT, but on hearing that such a test had been made, I quickly developed my own practice GMAT software. :)

B uses wrong tense (had not invented), wrong idiom (heard... of), and wrong tense again (having been made)
C is not a complete sentence (it basically says: Galileo, on hearing, he quickly built...).
D changes the meaning - he didn't build a telescope "even though" he didn't invent it. "Even though" indicates some kind of cause-effect connection. The original sentence is just telling us - he wasn't the inventor but he did build one soon after its invention.
E repeats multiple errors already discussed above

If one is clear about fragmentation and redundancy in a sentence, then he or she can sail through most of this topic with ease.

A is flawless.

B Had not invented is not correct 2. The main clause in the complex sentence does not have a subject.

C has redundancy with two subjects Galileo and he and a fragmentation with no predicate for the subject Galileo.

D is a fragment with no subject for the main clause.

E has redundancy since the coordinator 'but' and the subordinator 'even though' bring about out the same effect.

I really hate it when people post on a forum discussing an answer and call the right answer "flawless" How does that help anyone? And "A" is not flawless. It's a very flawed correct answer, but I am not saying it isn't correct.

Let's analyze the sentence


"Galileo did not invent the telescope", Nothing wrong with this. Has a subject past verb and object



"but on hearing, in 1609," This is very awkward also it's very unclear that this is a coordinating conjunction at first. It only becomes clear after reading. Also it's sloppy to use a but clause and then use a subordinating conjunction right after in "That":


"that such an optical instrument had been made," . So sloppy to start a coordinating conjunction with a "that clause"

he quickly built his own device from an organ pipe and spectacle lenses. This makes sense only if we assume the but is a coordinating conjunction and the that began a subordinating conjunction therefore the "he" part doesn't make a double subject.


It's very easy to read the but as a comparison and not a coordinating. They do use a comma though to give you a hint. However, I would hardly call starting a coordinating conjunction with a subordinating as flawless writing. That is a crappy response. It's a very crappy sentence even if it's correct. And no one would write like this, where they use a past verb, a participle, a past perfect and a past.

we can hear of something and we can hear of an idea.

I can hear of scholarship for mba in us
I can hear that you get the scholarship.

if we wan to say that we hear of an idea, we use that-clause to express an idea. we do not use noun+doing to express this idea. if we use this pattern, the meaning is "hear of +noun".

depending on meaning needed to express, we can use "hear+noun" or "hear + that-clause".
the meaning in this context require us to use "hear+that-clause".

Hi all.

Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he quickly built his own device from an organ pipe and spectacle lenses.

Since it is not difficult to understand the meaning of this sentence, let’s quickly get into the error analysis:

1. Use of past perfect tense is correct because 1609, the telescope had been already made and after that Galileo made his own version of the instrument. So there are two past events and “had been” correctly denotes that telescope was first made and then Galileo came up with his own version.
2. “but” correctly presents the contrast.
3. No errors.

PoE:

a) Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he: Correct for reasons stated above.

b) Galileo had not invented the telescope, but when he heard, in 1609, of such an optical instrument having been made, Incorrect.
1. Use of “had not invented” is incorrect because the sentence here just presents a general fact that should be written in simple past tense.
2. Use of “having been made” is also incorrect in this choice.
3. This choice also misses the subject “he” for the verb “built”.

c) Galileo, even though he had not invented the telescope, on hearing, in 1609, that such an optical instrument had been made, he: Incorrect.
1. Same verb tense error as in Choice B.
2. Use of pronoun “he” after “even though” is incorrect because Galileo has already been mentioned in the beginning of the sentence. This construction makes Galileo hanging without a verb.
3. Use of “even though” is incorrect. This expression is used to present contrast in that it denotes two opposite situations. For example:
Even though he is poor, he has managed to go to a good B school.
However, this choice does not present opposite situations. It simply says that Galileo did not invent telescope but he later developed one. There is co opposite things going on in here.

d) Even though Galileo did not invent the telescope, on hearing, in 1609, that such an optical instrument had been made,: Incorrect.
1. Use of “even though” is incorrect as in Choice C.
2. Absence of “he” before “built” leaves this verb without any subject.

e) Even though Galileo did not invent the telescope, but when he heard, in 1609, of such an optical instrument being made, he: Incorrect.
1. Use of “even though” is incorrect.
2. Use of “but” is redundant because “even though” already presents the contrast.

Hope this helps. :)
Thanks.
Shraddha



Nice explanation,
Some query want to clarify.
1. Is the use of "heard of" correct?
2. For E, i do understand the redundant stuff. Can you explain why the use of "even though" is incorrect.

Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he quickly built his own device from an organ pipe and spectacle lenses.

(A) Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he - CORRECT.. "did not invent" simple past tense is rightly used here as we are talking about a simple fact
(B) Galileo had not invented the telescope, but when he heard, in 1609, of such an optical instrument having been made, - no reason to use past perfect "had not" since we are presenting a simple fact and therefore simple past tense is preferred + "having been made" is incorrect
(C) Galileo, even though he had not invented the telescope, on hearing, in 1609, that such an optical instrument had been made, he - "even though" is to present a contrast but here there is no contrast, Galileo made telescope on hearing that it had been made earlier + the first "he" after "even though" is not required as "Galileo" is mentioned earlier
(D) Even though Galileo did not invent the telescope, on hearing, in 1609, that such an optical instrument had been made, - same problem as option C with "even though" + "he" missing after "made,"
(E) Even though Galileo did not invent the telescope, but when he heard, in 1609, of such an optical instrument being made, he - same problem as option C with "even though" + "even though" and "but " cannot be together

Hello Experts,

I wanted to understand the structure of this sentence.

Quote:
Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he quickly built his own device from an organ pipe and spectacle lenses


According to my understanding the structure is something like the below

Independent Clause, modifier, Independent clause

My question is, how do we identify that the modifier is not modifying the preceding clause but modifying the following one?

Can you put some light on this?

@Pikolo

The doubt is whether the modifier modifies the IC in front or the IC at the end.

Cue 1. There is a comma plus coordinate conjunction' 'but' before the modifier. We do not join a modifier with a conjunction; We splice a modifier with a comma. Therefore, the phrase starting with 'but' should modify the clause at the end.
Cue 2. However, indicates a contrast and there is nothing to indicate that the modifier is in contrast to the first IC. It should, therefore, be related to the second IC and in fact, it is quite rational to say he was not the originator but a follower. This confirms, that the modifier modifies the IC at the end
The presence of 'but' might confuse sometimes. 'But' is a genuine connector of the second part starting with the modifier phrase 'on hearing …" and followed by the essential main clause of the second part. The 'but' cursor reveals the subsequent part as an independent entity from the previous one.
