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,
C. Galileo, even though he had not invented the telescope, on hearing, in 1609, that such an optical instrument had been made, he
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, in 1609, of such an optical instrument being made, he

I would go with A.

A: Correct
B: wrong use of verb tenses -- had not invented implies that he will invent the telescope in the future
C: Galileo, on hearing that such an optical instrument had been made, he -- totally wrong
D: missing "he" at the end
E: "even though" and "but" are redundant

B, D -- are out.. "he" is missing before "quicklly"
C -- Galileo,...,he .. he is redundant
E. eventhough .. but --> redundant and "being made" --> wrong

A -- looks better.

Galileo didn't invednted (pastense),... optical instrument had been made.(past perfect -- passive voice.)

pefect..

To be frank i found it tough

Did not invent should be correct since invention is one time event
had not invnted deviates us thinkin he had not invented but can invent later .So eliminate B,C
NOw remains A,D,E :
E is eliminated since even though... but usage is not suggested
D is eliminated since HE is missing here statement apopears incomplete
A is perfect => IMO A

Correct useage of tenses, right placement of but.
In GMAT, not always but most of the times, you can eliminate choices with 'having' & 'being'.

noboru,

I think if there is some contrast in the sentence and conjuction is present then we need a subject. For example,
Although X...., subject
x........, but (pronoun-x)/y.........

Hi,
But in D, there is actually a || between did not invent and built, so I dont follow you when you say that "he" is needed there.
Could you clarify?
Thanks!

Hey guys,

I've always liked this question. My approach:

First, whenever I see a question with a large portion underlined and without a clear (to me) decision point in that underline, I like to look at the first and last word of the answer choices to see if I can find a quick decision point. Very frequently the first or last words are different and you can determine whether you need one or the other.

Here, three use the last word "he" and two do not, so that became a first decision point for me. You'd need "he" in this case to refer back to Galileo unless the verb that follows "quickly built" is set up as a parallel verb to another past tense event before it. Because that doesn't happen in B or D, they're both incorrect.

The first words, either "Galileo" or "Even though Galileo", also note a decision to be made - here, you have to set up a transition between "did not invent the telescope" and "built one quickly after it was invented (paraphrase)". That can be done either with "Even though" at the beginning or "but" halfway through, but not with both. Therefore, E, which does both, is incorrect.

Keeping on that theme, check C for that transition - C uses "even though", but does so as a modifier to describe Galileo. Because modifiers separated by commas are nonessential information, you can remove them to check the rest of the sentence. Here, you'd then have:

Galileo he quickly built...

That's a redundant, unnecessary use of a pronoun and it's used without separation, so it's incorrect. A, although incredibly awkward to the ear, is the only one left standing without error, and is therefore correct.

(a)
(b) Galileo had not invented the telescope, but when he heard, in 1609, of such an optical instrument having been made,
(c) Galileo, even though he had not invented the telescope, on hearing, in 1609, that such an optical instrument had been made, he
(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, in 1609, o such an optical instrument being made, he

Here your ability to notice redundancy is being tested.
In E the idea of contrast is already expressed in but or even though so you don't need both to express that idea. E is out.
In D we want to express that there is a contrast but the way eventhough is used here kind of alters the meaning of the sentence. Even though also means in spite of the fact that, and that is not the idea that we want to express (according to the original sentence).
D is out.
In C, for the same reason as D you can eliminate C.
In B, the verb tenses used are not correct. "Galileo had not invented the telescope" the words in red should have been written in the simple past tense because what Galileo did was in fact in the past. "of such an optical instrument having been made" the words in blue should have been in the past perfect tense b/c that occurrence happened before an occurrence (Galileo did not invent the telescope) that took place in the past.

A is correct. On hearing is like saying upon hearing or right after he heard. That is the correct idiom.

There is one grammatical flaw in D. "that such an optical instrument had been made," Right at the end the pronoun "he" should have been placed.
