"Theory that..ours was" sounds awkward.

I would go with E.

A and D out.... because Galileo's theory......reinforced those of Copernicus..... what those of Copernicus??

In B, the sentence implies that Galileo's theory reinforced the solar system of Copernicus... Galileo's theory that ours was indeed a solar system......reinforced (theory reinforced) that (solar system) of Copernicus

I choose E

This is what original statement does:
1)Affirms that our solar system is a real thing i.e. a solar system.
2)And that in this system all the planets revolve around sun.

E is tempting but it does not capture the essence of the item 1). B gets closer but it is structured in a funny way.
May be B?

One mean little SC though.

Only B and E stand out....It is a close call between both of them..
E is fine structurally, but has different meaning. B stays close to the meaning of the sentence.
Anyways, on the exam day I would have gone for E.....

theory is singular. so it should be "reinforces that of" not "reinforces those of". On elimination, down to B and E.

B is wordy as compared to E. E doesnt distort the meaning, nor do there seem to be any obvious errors. I'd go with E.

What if we tweak B a bit?

Galileo's theory that ours IS indeed a solar system, in which Earth and other planets revolve around the sun, reinforceS that of Copernicus

Would you agree E is not completely capturing what is provided in the original?

IMO, confusion comes from the use of 'was' and past tense in B.

well asaf, had the choice B been worded as you've suggested, it would've made the question a lot tougher. Happily, it isnt so.

Another problem with the original B

"B) ours was indeed a solar system, in which Earth and other planets revolve around the sun, reinforced that of Copernicus"

is that it uses was (past tense) with revolve (present continuous) tense. Tense must be kept same throughout. Hence, another reason to eliminate B.

I feel that even if B used "is" instead of "was" it would still be incorrect as we won't know what "ours" is referring to.

I think it is B.

B maintains the tense.
Theory was in past, earth still revolves around the sun

KUDOS
So, here is OE:

The sentence creates a parallel between Galileo's theory and Copernicus's theory, as you can se when you simplify the sentence structure: Galileo's theory ... reinforced those of Copernicus. The original sentence is right to try to compare theory to theory, but those is the incorrect pronoun; since theory is singular, the pronoun that refers to it needs to be that. Eliminate (A) and (D). Next, reinforced needs to be in the past tense like was earlier in the sentence. Eliminate (E). Finally, (C) presents less clear and less direct alternative to (B), leaving (B) as the right answer.

OA is B (Kaplan question)

This one is so strange... "ours was indeed a solar system" What is ours? Cows? cars?

I have chosen E because is the only sentence that makes sense...

can someone explain the "ours" plz?

Thx

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

A) ours was indeed a solar system, in which Earth and other planets revolve around the sun, reinforced those of Copernicus WRONG as ours wrongly modifies theory

B) ours was indeed a solar system, in which Earth and other planets revolve around the sun, reinforced that of Copernicus WRONG as ours wrongly modifies theory

C) our solar system was indeed solar for Earth and the other planets revolve around the sun, reinforced Copernicus' CORRECT, "for" is used as "because", does not change meaning, and reinforced Copernicus's theory (cannot use those of Copernicus as Galielo have only one theory so either "G theory...that of Cs" or "G theory... reinforces THE THEORIES OF Cs"

D) our solar system was indeed solar, in which Earth and other planets revolve around the sun, reinforced those of Copernicus WRONG - "those" of Copernicus is wrong here, that of Copernicus would have been correct

E) Earth and the other planets revolve around the sun in our solar system reinforces that of Copernicus WRONG - changes meaning
