a. wrong ---> use of "that" in " that scattered" indicates that the glacier scattered the remains rather than river.
b. wrong ---> awkward with the usage of 'that'
c. Correct --> intended meaning given , fed by....is a verb-ed modifier correctly modifying prehistoric river. use of simple past tense scattered to indicate the
the occurrence of this event in the past.
d. wrong ---> change in meaning
e. wrong ---> incorrect usage of the idiom "evidence of favour" plus change in meaning of the sentence.

IMO option C is correct.

(A) favoring the hypothesis of a prehistoric river fed by a nearby glacier that- Incorrect - Meaning issue sentence seems to convey that it was glacier that has scattered the bones, intended meaning should be river that has scattered the bones.
(B) that favors the hypothesis of a prehistoric river that was fed by a nearby glacier and that - Incorrect- awkward construction, that has too many possible antecedents.
(C) favoring the hypothesis that a prehistoric river fed by a nearby glacier - Correct
(D) in favor of the hypothesis that a prehistoric river was fed by a nearby glacier and that - Incorrect -meaning issue - As sentence seems to imply that evidence is doing favour, which is wrong.
(E) of favor for the hypothesis of a nearby glacier that fed a prehistoric river and - Incorrect - meaning issue- sentence seems to imply that there are two types of evidence one that favors, and one that don't.

(A) favoring the hypothesis of a prehistoric river fed by a nearby glacier that

Usage of "hypothesis of" is wrong.

Quote:

(B) that favors the hypothesis of a prehistoric river that was fed by a nearby glacier and that

Usage of "hypothesis of" is wrong.

Quote:

"favouring" is modifying "evidence" correctly and that clause is logically referring back to "hypothesis".

Quote:

(D) in favor of the hypothesis that a prehistoric river was fed by a nearby glacier and that

The second "that" will also modify the "hypothesis". Hence, meaning is getting distorted with this usage.

Quote:

(E) of favor for the hypothesis of a nearby glacier that fed a prehistoric river and

Usage of "hypothesis of" is wrong.

IMO OA should be C.

(A) favoring the hypothesis of a prehistoric river fed by a nearby glacier that
favoring modifies “evidence”. “That” modifies glacier: wrong. It’s “a prehistoric river” scattered the mammals’ remains, not “a nearby glacier” scattered.

(B) that favors the hypothesis of a prehistoric river that was fed by a nearby glacier and that
Since GMAT prefers that clause, we use “the hypothesis that” instead of “the hypothesis of”. Moreover, “a prehistoric river that … and that …” is that clause parallel but there is no verb go with “river” -> wrong.

(C) favoring the hypothesis that a prehistoric river fed by a nearby glacier
“fed by a nearby glacier” modifies “a prehistoric river”, “a prehistoric river … scattered…”: correct

(D) in favor of the hypothesis that a prehistoric river was fed by a nearby glacier and that
we use V-ing modifer instead of a noun

(E) of favor for the hypothesis of a nearby glacier that fed a prehistoric river and
Same as (D)

The correct answer is C

(A) is incorrect because it does not provide a clear connection between the fossils and the hypothesis. The phrase "favoring the hypothesis of a prehistoric river fed by a nearby glacier that" is not as concise and clear as the correct option.
(B) is incorrect because it repeats the phrase "that" unnecessarily, making the sentence wordy and less clear.
(C) This option is grammatically correct and gives clear meaning that the river scattered the fossils. Hence, Correct option
(D) is incorrect because it changes the meaning of the sentence by using "in favor of the hypothesis," which does not convey the intended meaning as effectively as the correct option.
(E) is incorrect because it changes the word order and structure of the sentence, making it less clear and less grammatically correct.

Paleontologists at the Montbrook fossil dig typically find the isolated bones and teeth of prehistoric mammals buried at regular intervals; the location of these fossils is evidence favoring the hypothesis of a prehistoric river fed by a nearby glacier that scattered the mammals’ remains after the decay of their soft tissue.
HERE HYPOTHESIS NEEDS TO BE FOLLOWED BY THAT. HENCE A,B,E ARE OUT
This is a cause and effect sentence.
RIVER FED BY GLACIERS - SCATTERED THE EVIDENCE.

(A) favoring the hypothesis of a prehistoric river fed by a nearby glacier that
THE PLACEMENT OF THAT IS INCORRECT

(B) that favors the hypothesis of a prehistoric river that was fed by a nearby glacier and that
TOO MANY THATS ARE BEING USED WHICH ARE NOT NECESSARY

(C) favoring the hypothesis that a prehistoric river fed by a nearby glacier
THIS IS PERFECT. USAGE OF THAT IS CORRECT.

(D) in favor of the hypothesis that a prehistoric river was fed by a nearby glacier and that
WE DONT NEED TWO THATS SINCE ITS A CAUSE AND EFFECT STATEMENT.

(E) of favor for the hypothesis of a nearby glacier that fed a prehistoric river and
OF FAVOUR IS INCORRECT.

CORRECT ANSWER IS C

(A) favoring the hypothesis of a prehistoric river fed by a nearby glacier that
"hypothesis" should be followed by "that" rather than "glacier + that". Therefore eliminate this.
(B) that favors the hypothesis of a prehistoric river that was fed by a nearby glacier and that
instead of "that favors" we should use "favoring". Therefore eliminate this.
(C) favoring the hypothesis that a prehistoric river fed by a nearby glacier
Corrects the mistake of option A. Lets keep it.
(D) in favor of the hypothesis that a prehistoric river was fed by a nearby glacier and that
"favoring" should be used instead of "in favor". For this reason lets eliminate this option.
(E) of favor for the hypothesis of a nearby glacier that fed a prehistoric river and
"favoring" should be used instead of "of favor". For this reason lets eliminate this option.

Therefore the correct option is option C.

Experts' Global Official Explanation:

Verb Forms + Idioms + Grammatical Construction + Meaning + Redundancy/Awkwardness

Understanding the intended meaning is key to solving this question; the intended core meaning of this sentence is that the location of the prehistoric mammal fossils is evidence favoring the hypothesis that a prehistoric river fed by a nearby glacierscattered the mammals’ remains.

A. Trap. This answer choice incorrectly modifies “glacier” with “that scattered the mammals’ remains…”,incorrectly implying that the glacier itself scattered the remains; the intended meaning is that that the river fed by the glacier scattered the mammals’ remains. Further, Option A incorrectly uses the unidiomatic construction “hypothesis of” rather than the idiomatic construction “hypothesis that”; please remember, “hypothesis that” is a correct, idiomatic construction.

B. Trap. This answer choice fails to maintain parallelism between “that was fed by a nearby glacier” and “that scattered the mammals’ remains…”; please remember, any elements linked by a conjunction (“and” in this sentence) must be parallel. Further, Option B incorrectly uses the unidiomatic construction “hypothesis of” rather than the idiomatic construction “hypothesis that”; please remember, “hypothesis that” is a correct, idiomatic construction.

C. Correct. This answer choice correctly modifies the noun phrase “a prehistoric river” with the verb modifier “fed by a nearby glacier” and the verb phrase “scattered the mammals’ remains…”, conveying the intended meaning- that the location of the prehistoric mammal fossils is evidence favoring the hypothesis that a prehistoric river fed by a nearby glacierscattered the mammals’ remains. Further, Option C avoids the parallelism error seen in Options B and D, as it does not employ any conjunctions. Additionally, Option C correctly uses the idiomatic construction “hypothesis that”. Besides, Option B is free of any awkwardness or redundancy.

D. Trap. This answer choice fails to maintain parallelism between “that a prehistoric river was fed by a nearby glacier” and “that scattered the mammals’ remains…”; please remember, any elements linked by a conjunction (“and” in this sentence) must be parallel. Further, Option D suffers from a pronoun error, as in the pronoun phrase “and that scattered…” the pronoun “that” has no clear antecedent. Additionally, Option D uses the needlessly wordy phrase “evidence in favor of”, leading to awkwardness.

E. This answer choice alters the meaning of the sentence through the phrase “that fed a prehistoric river and scattered”; the construction of this phrase incorrectly implies the glacier itself scattered the remains; the intended meaning is that that the river fed by the glacier scattered the mammals’ remains. Further, Option C incorrectly uses the unidiomatic construction “hypothesis of” rather than the idiomatic construction “hypothesis that”; please remember, “hypothesis that” is a correct, idiomatic construction.

C is the best answer choice.

Hi Bunuel , GMATNinja , and other Experts,
What's wrong with B apart from idiom error? I think it clearly conveys the meaning that hypothesis is about a river that was fed by glacier and that scattered the bones away. Both are clauses and are parallel and modify river.
