GMAT Club World Cup 2022 (DAY 1): One perplexing result of General

Meaning:
One perplexing result of General Relativity is the prediction that gravitational singularities lie at the heart of black holes, a point where the laws of physics no longer seem to apply. This result has been supported by subsequent research.
Errors:
A)
i) Hearts is incorrect. Heart in singular form is correct
ii) And that has been...research is misplaced modifier
B)
i)Meaning distortion: prediction at the heart of black...singularity
ii)Misplaced modifier point modifying gravitation instead of heart
C)
i) Incorrect modifier modifying singularity instead it should be modifying heart
E) Misplace modifier like B)

(A) One perplexing result of General Relativity is the prediction that gravitational singularities lie at the hearts of black holes, a point where the laws of physics no longer seem to apply, and that has been supported by subsequent research.

“a point where” is the appositive that supposedly refers to a singular noun ahead. However, there is no such singular noun in front.


(B) One perplexing result of General Relativity is the prediction at the heart of each black hole of a gravitational singularity, a point at which the laws of physics no longer seem to apply, but a prediction that has been supported by subsequent research.

“the prediction at the heart of each black hole” this part implies that the prediction exists at the heart of each black hole. Unintended meaning.


(C) One of the perplexing results of General Relativity is the prediction, supported by subsequent research, that at the heart of each black hole lies a gravitational singularity, a point at which the laws of physics no longer seem to apply.

Correct answer because now an appositive correctly refers to “gravitational singularity”


(D) The prediction of a gravitational singularity at the heart of each black hole, a perplexing result of General Relativity but one that is supported by subsequent research, is a point where the laws of physics no longer seem to apply.

this choice literally says that the prediction is a point where the laws no longer apply. Unintended meaning.


(E) The prediction that at the heart of each black hole lies a gravitational singularity, a point at which the laws of physics no longer seem to apply, is a perplexing result of General Relativity but supported by subsequent research.

In the construction “A but B” elements should be parallel. However, here A is a noun and B is an adjective.

So C

Hi. I am giving points this time but please make sure to address why the other answer choices are incorrect.
Thx.

Hi Jainam24,

Please make sure to label OA and correct answer choice. It is not really clear even after reading these a few times.
I assume you picked D as the correct answer but not sure and thus not able to give points. Sorry.

Good luck tomorrow!

Okay, we can eliminate options based on split answers. There are multiple choices but let us start with the point at which rules do not apply. It is clear that a gravitational singularity is the point at which the laws of physics no longer seem to apply, so options A and D are out since they imply that black holes and research are the points. Left with B,C and E. Option B is a little redundant with prediction used more than once to serve the same purpose. Between C and E, C is the most concise and well structured getting the point across as well

Answer - C

bb Bunuel ThatDudeKnows MartyTargetTestPrep avigutman egmat please clarify as to what 'the point' modifies and how do we determine it? I thought it modifies black hole but seems like it is modifying singularities. I do not know why, moreover both these nouns are plural so how can it even modify any of these. If it is modifying black holes, then how is it allowed to skip the preceding verb 'lies'. Meaning wise, both the words seem to make sense for reference except the pluraity issue. How do we decide?

Which version are you talking about? In the correct version both "black hole" and "singularity" are singular, and "the point" modifies "singularity."

The correct answer choice makes everything singular:

(C) One of the perplexing results of General Relativity is the prediction, supported by subsequent research, that at the heart of EACH black holE lies A gravitational singularitY, A poinT at which the laws of physics no longer seem to apply.

Rather than talking about black holeS, gravitational singularitieS, and pointS, the construction of this answer choice allows us to discuss how each (which is singular) yadda yadda yadda. Make sense?

ThatDudeKnows ok but what is it referring to blackhole or singularity and how do we know that without technical info?

Options D & E can be eliminated for "the prediction" (incorrect) vs. "one of the predictions" (correct)
Option B alters the meaning.
Between Option A & C, A has issue in parallelism of "that..." which is eliminated in C.
Hence Option C.

Open for discussion.
