Hey All,

Just thought I'd weigh in on this one, since the official answer seems to be lacking.

The answer is A. In C, the "during" is unclear, because it makes it sound as if WE are seeing them NOW as if we were seeing them during the formation of the universe. This isn't the intended meaning of the sentence.

In D, the comparison is incorrect. It makes it sound as if they appear to us NOW as they appeared to us during the formation of the universe. But we weren't there back then. Sadly. E does this in an even more egregious way.

In A and B, we have to choose between the past tense and the past perfect. However, we should only be concerned about the tenses in the independent clause that comes after the semicolon. The only verb there is "see" which is in the present, so we only need to use the simple past tense to express an action occurring BEFORE the "see" action. The only time we would need past perfect would be if we had a verb in the clause that was already in the past tense, and we wanted to express an action occurring before THAT.

Hope that helps!

Hi Tommy,
I did not not undersatand your explanation. Do you mind elaborate - A vs D

we see them as they were during vs they appear to us as they did in

we see them as they were during - we see the Quasars as Quasars were during Does'nt this mean that we "currently" see Quasars as Quasars were in the past(during the formation of the universe)

they appear to us as they did in Quasars appear to us as Quasars did inQuasars looks the same as they were in the past

i think - both mean the same.

Thanks in advance for your explanation.

Regards

No.. there is slight misunderstanding in your second statement...
they appear to us as they did in - actually gives an impression that you saw them before (during formation) and hence you comment that they look like they did in the past.... once you see them again...currently..

But the first statement.... gives an impression that u see them as you have known about them during formation... it does NOT give an impression that you travelled back in time and saw them forming... and hence it is correct..

Hope this helps... else Tommy would respond back to you on this...!

JT is absolutely right. Thanks for clarifying that one for me.

In the correct answer, we have "as they were", the "they" being the quasars, the "were" being merely the action of being.

In D, we have "as they did", the "they" being the quasars, the "did" standing in for "appear to us". They could not have appeared to us in the distant past, because we weren't around.

Hopefully that helps. Thanks again, JT!
