OA is (B).
But, Why is (E) wrong?? also, these are generally accepted theories then why use past tense for them ?

I eliminated A because of "those of" since we are comparing a theory with another theory.
C and D are primarily eliminated because of the word "solar" not making any sense without "system"

For me this was between B and E. E looks gramatically correct, BUT it changes the meaning of the original sentence. The original sentence says that the theory was that "our [system of planets] was a solar system" and the words "solar system" are modified by "in which..." that gives more information about what a solar system actually is.

E changes the meaning of the "theory" discussed in this sentence.

So i chose B

B says that ours “was” a solar system. Does that mean that our is not a solar system now? Remember please they are still live and relevant theories.Are we not supposed to use simple present for eternal and universal facts?

When there is a blatant grammatical error, I am afraid that will take precedence over other factors in the POE.

Let us appreciate that solar system is the specific name given to the Sun and its family. Any other star or its family is not called solar. Therefore, there is no question of either our solar planets orbiting some other stars or other planets belonging some other stellar system orbiting our Sun.

I would rather be happy to eliminate B for use of inappropriate tense and go with E. Then, I will not be surprised if Kaplan comes out with some unusual thesis to its defense.

(A) ours was indeed a solar system, in which Earth and other planets revolve around the sun, reinforced those of Copernicus
(B) ours was indeed a solar system, in which Earth and other planets revolve around the sun, reinforced that of Copernicus
(C) our solar system was indeed solar for Earth and the other planets revolve around the sun, reinforced Copernicus'
(D) our system was indeed solar, in which Earth and other planets revolved around the sun, reinforced those of Copernicus
(E) Earth and the other planets revolve around the sun in our solar system reinforces that of Copernicus

Answer: B (as far as I can see, this is the best possible answer. I do agree that 'ours was' does not seem right)
A - We are talking about Galileo's theory reinforcing Copernicus' theory. Theory is singular here. So, it should be 'that' and not 'those'.
C - nonsense.
D - nonsense.
E - alteration in meaning. In original, Galileo theorised about what sort of system ours is -> solar system (i.e. every planet revolves around the sun). However, in option E, Galileo theorised about the revolution of the planets.

Pretty sure B is correct.

Quote:
...that ours was indeed a solar system, in which Earth and other planets revolve around the sun, reinforced that of Copernicus.

The use of simple past seems fine, because when Galileo came up with his theory, it was just that: a theory. It had not been proven to be a fact, yet.

This must be in present tense, because it's simply the definition of a solar system.

This must be in simple past, too, since the sentence describes a situation in the past. At that time, Galileo's theory reinforced that of Copernicus.

So either both the red and the blue part of the sentence are in a present tense or both are in a past tense, as is the case in answer choice B. Choice E would take care of the tenses, as well, but it integrates the term "solar system" into its own definition. Both "planets revolve around the sun" and "solar system" basically mean the same. The difference between B and E with regard to this is that B does refer back to the term "solar system" in order to explain it in a relative sentence, while E fails to establish that causal/explanatory connection between planets revolving around the sun and what that means for the type of our planetary system.

For me it is B .
In case of answer choice E , there is a change of meaning .
Original meaning does not state that "Earth and the other planets revolve around the sun in our solar system" but rather states that "Earth is a solar system" and the fact that earth and other solar systems rotate around the sun is only a trait of that particular solar system .
Whereas option E focuses on the fact the earth and other planets revolve around the sun instead of emphasizing on the fact that ours ,whatever it is , is a solar system .

Galileo's theory that ours was indeed a solar system, in which Earth and the other planets revolve around the sun, reinforced those of the copernicus.

E. Earth and the other planets revolve around the sun in our solar system reinforces that of copernicus

How is B right? Moreover "reinforced that of the copernicus" is wrong.

E is the only logical answer. I've come across some of these Kaplan questions before and they always leave you scratching your head.

IMO
I had went with answer 'E' but after explanation and careful consideration i think answer is 'B'
Galileo theoy is "ours was indeed a solar system" then it used modifiying phrases separated by comma then compared it with Copernicus theory

In 'E' although tenses is correct but still it change the theory which Galileo had put forward

GMAT Experts please resolve the ambiguity.

@Anuj, I feel the answer is B for 2 reasons:

1) the theory by Galileo was in the past and it reinforced the Copernicus theory which also was in the past. So the action needs past tense.

2) the planets and the Sun make the solar system and not that they revolve in the solar system.

Hence B.

But I would still want Chiranjeev/Payal to throw some light.

Thanks.

I am still not convinced with the answer. Was the theory valid in past and does not hold true now ? Also, the second reason that sun and planets make the solar system is not clear to me.

Galileo's theory that ours was indeed a solar system, in which Earth and other planets revolve around the sun, reinforced those of Copernicus.

Meaning :
1. Galileo's Theory Reinforced Theory of Copernicus.
2. G's Theory is "Ours was indeed a solar system, in which Earth and other planets revolve around the sun"

Error Analysis :
1. "those of" - those a plural is used to refer back to Theory singular noun.

POE.
A) ours was indeed a solar system, in which Earth and other planets revolve around the sun, reinforced those of Copernicus
Incorrect - Explained Above

(B) ours was indeed a solar system, in which Earth and other planets revolve around the sun, reinforced that of Copernicus
Correct - Corrected plural Error with replacement of "that"

(C) our solar system was indeed solar for Earth and the other planets revolve around the sun, reinforced Copernicus'
Galileo's theory reinforced Copernicus' - Correct (ellipses - theory silent )
our solar system was indeed solar for Earth and the other planets revolve around the sun - illogical meaning and sentence structure sound incorrect

(D) our system was indeed solar, in which Earth and other planets revolved around the sun, reinforced those of Copernicus
1. Those - Plural refers to singular theory
2. our system was indeed solar - Indeed solar o_0 -- Indeed solar something fishy .. but can be true - lets not eliminate on this (Although it is nonsensical)
3. Earth and other planets revolved around the sun - Past tense revolved, so have they stop doing that - No - It is universal fact- must be presented with simple present.

(E) Earth and the other planets revolve around the sun in our solar system reinforces that of Copernicus
G Theory reinforces that of Copernicus - Correct
Theory that Earth and the other planets revolve around the sun in our solar system - correct

the option E, is grammatically correct but introduces subtle change of meaning.
Original Says Theory is "Our is solar system, In which (Non-Essential) Earth and other planet revolve"
Option E says theory is "Earth and Other planet revolve in our solar system " ---- Did you notice the change in meaning.

Change in meaning should be avoided as far as possible.

P.S bumping .. it may help someone

I am skeptical about the OA ‘B’. Let’s look at it this way. What is the truth? Is ours still a solar system or was it so only in Galileo’s time? Notwithstanding other errors, IMO, A to D are wrong for this one single reason.

One problem about E is that if Earth and the other planets revolve around the sun in our solar system, what do they revolve around in other systems? GOK

If one can make bold to ignore this insinuation about E, that may perhaps make the correct choice by compulsion rather than by conviction.

Hey guys quick question about the answer choice A. Why can't a single a single theory reinforce multiple theories? Couldn't Copernicus have made multiple complex theories around the basis of the sun being the center of the solar system? Is it because you cannot use the pronoun those with the original singular concrete noun of theory?

Absolutely right! When the pronouns "that"/ "those" are used to create copy / copies of noun/nouns, the pronoun must agree in number with the noun. The following example is from Manhattan GMAT:

Wrong: Her company is outperforming THOSE OF her competitors.
Right: Her company is outperforming THE COMPANIES OF her competitors.

Why option (E) is wrong? In my opinion both B and E are correct.
We can consider the sentence in the present tense too. And, structure of (E) express more clearly than that of (B).

There is a major issue with option B: when stating a universal truth in indirect speech, simple present must be used, even when the speech is made in the past.

I knew that the sky was blue... wrong.
I knew that the sky IS blue... right.

For this reason using past tense (ours was indeed a solar system) is definitely wrong. Option B cannot be the OA.

Hi,

There is a lot of confusion in this question. I think E is correct because the sentence is telling a fact, which still holds true. Hence, B cannot be the correct answer.

But then I could see E changes the tense of Reinforce. It should be reinforced.

Still, I prefer marking E as the correct answer, which is wrong as per the given OA.

what is the antecedent for "ours"?

You do not need antecedents for first person and second person pronouns (e.g., I, you, my, our etc.) Antecedents are required only for 3rd person pronouns (he, she its, his, her its etc.). For example:

I am very close to being happy. ... in this sentence you do not need an antecedent for "I".

I agree with you - I have already posted my concern about the OA:

https://gmatclub.com/forum/galileo-s-th ... l#p1732203

But my concern is specifically for option E. If you say E is the correct answer, I can go ahead and update the OA for this question.

I think E change the meaning, and the past tense in G is still correct b/c the theory now no longer is accepted but the principle that Earth revolves the Sun is still accepted.
