The last portion of the sentence starting with "BY"...suggests that the sentence is in passive voice..

that leaves us with A , C and D

C is incorrect ...no logical referent for "that"

D ...incorrect...we are comparing the difference in detection

capabilities of two instruments...

We need "compared to " to convey that idea

A .. is best

Praet,

Your detailed explanations and thoughts on answer choices are very helpful, as always!

But, D sounds better to me out of all the cases. "fainter than" sounds better than "fainter compared to"

Thanks.

i think A and B are wrong because "sources twenty times fainter compared to those " means campared to sources, but here we have to compare telescope. C seems decent.

whats the official answer?

IMO, D is correct.

"Fainter than" is the correct idiom. We are comparing sources to other sources. Which sources? Those (sources) that can be detected by ground based intruments.

I vote for D too.

"fainter" already implies there is a comparison ... also as written above "fainter than" is correct.

twenty times fainter - mean we need a than so A and B out.

now by ground-based instruments means we need passive voice in the underline area. So E out.

Now comparison is between two type of sources. So "than those" is meaningful. Undoubtedly D is the answer.

IMO answer is C !

Someone above said "THAT" in C has no clear referent. I disagree, THAT in option C refers to LIGHT.
Here we are comparing the LIGHT captured by Hubble Space Telescope and LIGHT detected by ground-based instruments. So, we need THAT not THOSE THAT as written in D.

Please provide OA.

D it is.

We are comparing "sources"

"Hubble telescope will capture light from SOURCES 20 times fainter than those [SOURCES] that can be dectected by ground based instruments."

Thanks seekmba, I agree we are comparing sources. I confused with "light".

IMO..... D is the correct option. Fainter already shows that there is comparison between things..
fainter than seems good to me..
My answer D

Firstly I thought A is the answer, but when I went the explanations that comparison is for sources, I feel D is the better option of the two.

Whats the OA?

When using a comparative adjective ("-er") "than" is required, so "compared to" is wrong.
Answer (A) & (B) are wrong

We need to be clear on what is/are being compared.
There are two nouns in this question that are eligible for comparison, light (that) and sources (those)
For which noun can we use the comparative adjective "fainter"?
Though,
"Fainter" makes more sense with light,
and the verb detected is more appropriate for "light" than "sources"
Answer choice (C) is wrong. Why? Answer choice (C) is missing subject for the "can be detected...." phrase.

(C) The Hubble Space Telescope will capture light from sources twenty times fainter than that [light] can be detected by ground-based instruments.
(C) The Hubble Space Telescope will capture light from sources twenty times fainter than that [light] that [light] can be detected by ground-based instruments.

(D) The Hubble Space Telescope will capture light from sources twenty times fainter than those [sources] that [sources] can be detected detected by ground-based instruments.

Correct answer (D)

Thanks

We are comparing "sources" not light here.

"Hubble telescope will capture light from sources 20 times fainter than those [sources] that can be detected by ground based instruments."
D is correct. Good question

If A would have had COMPARED WITH than A would have been the correct ans .Off all the options provided D is the ans.D is correctly comparing light sources (plural ) with those (light sources)

sources can not be fainter logically
light can be gainter

so, C, not D is correct .
