Quasars are so distant that their light has taken billions of years to reach the Earth; consequently, we see them as they were during the formation of the universe.

(A) we see them as they were during

(B) we see them as they had been during

(C) we see them as if during

(D) they appear to us as they did in

(E) they appear to us as though in

https://www.nytimes.com/1986/05/06/science/powerful-source-of-gravity-detected-deep-in-the-universe.html

Since then several thousand such ''quasi-stellar radio sources,'' or quasars, have been discovered. Assuming the yardstick used to measure cosmic distances - the so-called red shift - is valid, many quasars are so far away their light has taken billions of years to reach the Earth. They are therefore seen as they were during the infancy of the universe and may be galaxies in an early, extremely brilliant stage of development.

Good job working through the tricky verb tenses here! Those who have said that the past perfect is not necessary are correct. Remember, we use the past perfect when talking about multiple past events in order to indicate distant (past perfect) vs. recent past.

In this sentence, we have a present event and a past event, so we use the simple present and past tenses: "we see them (now, in the present) as they were (in the past) during the formation of the universe."

Answer choice D has a little logical glitch. It sounds as though we're saying, "they appear to us now as they appeared to us in the formation of the universe." We certainly weren't around to see what they looked like way back then! Additionally, I don't like "IN the formation of the universe." The formation is a process, not a place, so the construction "DURING the formation" is preferable.

I am for A.
(A) we see them as they were during
Correct
(B) we see them as they had been during
Had Been is unnecessary
(C) we see them as if during
during is wrong
(D) they appear to us as they did in
Does not convey the correct meaning.
(E) they appear to us as though in
"though in" does not convey correct meaning.

My answer is A.

B. There is no need for Past Perfect because we don't have multiple past events
C. as if during is impossible because we weren't there during the formation of the universe
D and E are wrong because "they appear" as them being active doer is not as good as "we see" the quasars...

why is there no pronoun ambiguity here ? They can refer to both lights and quasars right?

pronoun after a semicolon refers to the first noun in the sentence,which is Quasars here.

Wrong meaning: In the part "as they did", the verb "did" is used to replace the already used verb "appear" (to avoid repition) - thus the meaning implied is that the way Quasers appear to us now is the same as they appeared to us when the Universe was formed. But, when the Universe was formed, we did not exist. Hence the sentence conveys an absurd meaning.

Hi

I agree with your interpretation. However, I have another question with regards to the use of "did". Is it legit to replace "did" for "appear"? "appear" is in present tense, and "did" needs a verb in simple past. Or I'm wrong? My decision was to eliminate D was precisely because of the tense mismatch.

Thanks

Is something bad with such POE?

(B) we see them as they had been during past perfect is unnecessary
(C) we see them as if during SEE AS requires clause/noun
(D) they appear to us as they did in APPEAR AS requires noun
(E) they appear to us as though in APPEAR AS requires noun

Thanks

Hi jawele , no, "did" does not need to match the simple present tense "appear."

Do, does, or did can "stand in" for previous verbs that are written in simple tense and that must change tenses in the sentence.

Option D requires a verb tense shift, from simple present to simple past, this way:
(1) They appear to us now as they appeared in the formation of the universe.

We do not have to say appeared.
We can use did, simple past tense, to substitute for appeared, also simple past tense.
(2) They appear to us now as they [i]did in the formation of the universe.[/i]

Sentences (1) and (2) mean exactly the same thing. Did = appeared

Hope that helps.

Hi generis

Thanks so much for responding to my query. Sure, but please note that my post was a question, so my explanations aren't water proof. Diving in ...

Manhattan prep provides a list of common standard English idioms, and one of the idioms in the list is "VIEW AS". It requires an object to complete the idea what is viewed although that's my reasoning, not Manh.p. Yet, the examples in the book seem to go in line with my idea. I can't quote any problem from OG/GMATprep now, but I'm sure that I have seen at least one. I feel that "SEE AS" can treated as analogous to "VIEW AS".

"APPEAR AS noun" and "APPEAR TO verb" again are two idioms from the list. If you take a stab at some Off problems, you'll realise that that's the case (such as in this one https://gmatclub.com/forum/combining-enormous-physical-strength-with-higher-intelligence-the-nea-87777.html#p1218844 or this https://gmatclub.com/forum/sunspots-vortices-of-gas-associated-with-strong-electromagnetic-79261.html#p1015216 (follow the comments in regard to this discussion), unless of course you will prove me otherwise.
