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.

A. sequence of tense.


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.

1. "Galileo did not invent the telescope" is an independent clause.
2. "but on hearing, in 1609, that such an optical instrument had been made" is a dependent clause.
3. "he quickly built his own device from an organ pipe and spectacle lenses" is an independent clause.

Sequense of events: "such an optical instrument had been made" occured before "Galileo did not invent the telescope" and "he quickly built his own device from an organ pipe and spectacle lenses". so

1. "Galileo did not invent the telescope" is in past perfect tense.
2. "but on hearing, in 1609, that such an optical instrument had been made" is in simple past tense.
3. "he quickly built his own device from an organ pipe and spectacle lenses" is in simple past tense.

so choices other than A violets these rules and are incorrect....

A.

I had a slightly different approach.

Besides C, D and E having all sorts of errors, I would eliminate C, D and E because even though would change the context slightly.
The original sentence emphasizes the fact that he wasn't the first person to invent the telescope. Inserting even though instead of but, the passage seems to emphasize the fact he did made the telescope and sounds more forgiving about the fact he wasn't the first.

Having been made on B is obviously wrong. so I went with A.

Does my reasoning make sense or valid? let me know.

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.

B. no reason to use past perfect tense.
C. redundant subject - Galileo and he
D. subject not present
E. 1609 is wrong. we need a preposition.

E: "even though" together with " but" is redundant--> out
D: "even though" forms two related clauses, we can't find the subject for th 2nd clause in D--> out.
B: yup, the use of past perfect is unsuitable here-->out
C: every part is disorderly displaced---> out.
A it is.

Lets use POE

You need had been -because instrument was built first and then Galileo heard
so, B and E - gone

OK , A,C and D

D - I like D if there was a ' he ' in the end , without that this sentence goes for a toss

C is no good as well , if you remove all non-required clauses - you are left with Galileo and he . Also , this sentence uses two had been - not a good way to describe sequence of events - gone

A is the answer

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!


hi noboru,
Let me try to work out your concern about (D).
First Look at "even though blah blah blah"
1. When we have a sentence beginning with "even though,...",the clause following "even though" is subordinate clause and we need the main clause which have S + V --> that why we need "he" working as a S here
2. "even though" is different in meaning with "but. "Even though" shows something paradox so it is not appropriate when applying in the meaning of this sc.
Hope it helps. Please correct me if i'm wrong

In "D", After using "on hearing", there should have been the use of "he" in the end. "he" is missing in "D".

The answer is A .
But for the qn what is wrong with two hads..
The invention is a one time activity and so past perfect tense shouldn't be used.
It should be ..he didn't invent..but not he had not invented(Its not continuing).
We are talking abt an instance of an event(invention), which didn't take place.

But if it happened even before something else in the past (hearing the news in this case), shouldn't past perfect be used? For example, "I had thought that he was wrong before he explained." Would it be wrong to say "He had already invented it when other people started to think about it"? If no, why would it be wrong to say "He had not invented when other people started to think about it"? Is it because it in fact did not happen, rather than "happened before something else in the past"?

D and E don't keep the meaning of the sentence by using "Even though"- The same for C. Be is incorrect because the tense of the the first verb is not correct. I choose A.
