(A) compared to those that can be detected
(B) compared to those they can detect
(C) than that can be detected
(D) than those that can be detected
(E) than those detecting
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.

(A) compared to those that can b detected
(B) compared to those they can detect
(C) than that can be detected
(D) than those that can be detected
(E) than those detecting 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.

(A) compared to those that can b detected
(B) compared to those they can detect
(C) than that can be detected
(D) than those that can be detected
(E) than those detecting 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."
