Although British and French abolitionists of the late 1700s predicted that manumission and the blockading of slave ships would gradually undermine it, slavery continued to be the dominant cultural and economic force in southern America until the end of the American Civil War in 1865.

prediction:- manumission and the blockading of slave ships will gradually undermine Slavery.
Since we taking about this in the past, so we will use past tense of will i.e. would.

Now the question is whether "it" will refer back to Slavery- so my answer will be yes, as it is nearest singular noun and "it" is refer back to slavery contextually as well.

So my pick will be A.

(A) would gradually undermine it (Correct. The sentence is representing a future condition in past so 'would' can correctly be used to express that. Besides, 'it' correctly refers to slavery.)
(B) to be a gradual undermining of it (This phrase is incorrect. 'Would' is the correct usage to represent a future condition occur in past. Besides, that clause doesn't have any verb which makes the clause incorrect.)
(C) would be a gradual undermining of slavery (A is better. Slavery is repeatedly used which makes the sentence awkward.)
(D) to gradually undermine slavery (Same as B. Also the construction of sentence convey the meaning that prediction was to gradually undermine slavery.)
(E) gradually undermining it (No verb for 'that' clause.)

(A) would gradually undermine it
Correct - This sentence is grammatically correct. The pronoun “it” refers to slavery, which is mentioned earlier in the sentence. 'Would gradually undermine' is a verb construction that matches the prediction made by the abolitionists.
(B) to be a gradual undermining of it
incorrect - This option changes the meaning of the original sentence. It suggests that slavery itself would be a gradual undermining force, which is not correct. Use of infinitive to be is incorrect.
(C) would be a gradual undermining of slavery
incorrect - This option also changes the meaning of the original sentence.
(D) to gradually undermine slavery
incorrect - usage of verb form infinitive “to undermine” is incorrect. "would" is preferred
(E) gradually undermining it
incorrect - undermining is not a verb. Also, this option changes the meaning of the sentence.
Answer A

This question tests us on verb tense and pronoun
As the first clause uses the word "predicted", the verb of the clause after "that" should be in future-in-the-past
-> We use "would" to express it
Hence, eliminate options B, D, and E

In option A, pronoun "it" has no antecedent -> Incorrect

Answer is C. Clear meaning with no error

I chose C

(A) would gradually undermine it
Pronoun " it" has no clear antecedent.
(B) to be a gradual undermining of it
"Predicted that" should be followed by independent clause. in the clause, the subject is " manumission and the blockading" , we need a verb, and " to be" can serve as verb. Also, pronoun it repeats the error in A.
(C) would be a gradual undermining of slavery
Kind of wordy, but seems to be best choice.
(D) to gradually undermine slavery
" to " can not be the verb in the independent clause.
(E) gradually undermining it
No verb in the clause, pronoun error.

(D) to gradually undermine slavery
-Suspected to be incorrect.
Rationale: The word "slavery" immediately follows this option.


(E) gradually undermining it
-Suspected to be incorrect.

Let's evaluate the answer options:

(A) would gradually undermine it

I think that this choice correctly refers to "slavery" by using the pronoun "it". The verb "undermine" is correctly in the future tense ("would undermine"), because it is something that British and French abolitionists predicted would happen in the future. (talking about a future event in the past)
(keep)

(B) The usage of "to be" is not appropriate in this context. We are talking about an action that would occur, not a state of being.
(eliminate)

(C) The word "slavery" is unnecessarily repeated. The original pronoun "it" clearly referred to "slavery." This seems redundant and awkward as well.
(eliminate)

(D) The infinitive "to" is not appropriate in this context. Also, this choice seems to be missing "would" which indicates future tense. We should be talking about a future event in the past tense.
(eliminate)

(E) This choice omits "would," altering the intended tense from future ("would undermine") to present ("undermining"). Issue with tense.
(eliminate)

A seems to be the best option, so I will go with A.

(A) would gradually undermine it
(B) to be a gradual undermining of it
(C) would be a gradual undermining of slavery
(D) to gradually undermine slavery
(E) gradually undermining it

Let us destroy it,

A) This choice appears to imply that the abolitionists' forecast was about something that would happen in the future, yet the sentence's context is about the past, not the future.
B)The answer makes the sentence wordy and uncomfortable.
C)This option modifies the meaning slightly by including the word "slavery" after "undermining."
D)This alternative is comparable, except it shifts the emphasis significantly.
E) It is the best choice and all are correct

Answer:E

(A) would gradually undermine it
(B) to be a gradual undermining of it
(C) would be a gradual undermining of slavery
(D) to gradually undermine slavery
(E) gradually undermining it

predicted (past tense) => verb in that clause will be "would + inf verb without to" => B,D,E out.
(A) would gradually undermine it
(C) would be a gradual undermining of slavery
gmat prefer the verb form to noun form but in this case pronoun "it" is ambiguous since there are some singular nouns in the sentence manumission, blockading, slavery, force, America, the American Civil War. If pronoun "it" is the subject of the first clause (right after although) it is fine to refer to "slavery".
Thus the best here is to use "slavery" rather than "it" in order to deliver clear meaning.
