The AXi3 language algorithm, one of the more than ten such algorithms that has been released last year, is making waves in the global scientific community due to its ability to mimic human writing, but it falls short on common sense.
A) has been released last year, is making waves in the global scientific community due to its ability to mimic human writing, but it falls
B) has been released last year, is making waves in the global scientific community because of its ability to mimic human writing, but falling
C) has been released last year, are making waves in the global scientific community having the ability to mimic human writing, but it falls
D) have been released last year, is making waves in the global scientific community for its ability to mimic human writing, but it falls
E) have been released last year, are making waves in the global scientific community because of its ability to mimic human writing, and falls

OFFICIAL EXPLANATION
THE PROMPT
This sentence contains three subject/verb pairs
→ Main subject/verb pair: One . . . is
Nested inside that main subject is the second subject/verb pair ([algorithms] that have been released).
→ algorithms that have been released contains the correct subject-verb pairing.
But one is its own singular subject.
→ [algorithms] that . . . have been released
See Notes, below.
That is a relative pronoun referring to algorithms.
Algorithms are plural.
Watch the subjects and verbs in relative clauses (clauses that begin with which, that, or who).
Relative pronouns are bona fide subjects that must have their own verbs.
In fact, think of a relative pronoun (that, who, which) as something that "eats up" one of the verbs. Once the verb is paired with, say, that, it is no longer available.
The verb must agree in number with whatever the pronoun stands for.
That refers to plural algorithms.
→ it . . . falls
ONE OF THE Xs
When you see "One of the Xs," look for the words that or who after "one of the Xs."
Almost always, the following rules will hold:
ONE OF THE Xs + that/who + VERB = plural verb for the word that
ONE OF THE Xs + VERB = singular verb for the subject ONE. (We are dealing with a that-clause; this construction
• DUE TO
→ GMAC tests this phrase often. It is rarely correct.
See whether you can replace "due to" with "caused by" or "attributable to."
If "caused by" works, then "due to" is correct.
If "caused by" does not work, then "due to" is incorrect.
→ That stands for plural algorithms. The singular verb is should be are.
• due to is incorrect
→ substitute caused by for due to.
Wrong: The AXi3 language algorithm . . . is making waves in the scientific community caused by its ability to mimic human writing.
→ The sentence means that the AXi3 language algorithm's ability to make waves in the scientific community IS due to XYZ.
This option does not name a noun such as ability to which due to could refer.
In addition, when due to is correct (on the GMAT, not often), the phrase frequently follows IS or ARE.
ELIMINATE A
→ see option A
• but falling is strange.
The phrase modifies the AXi3 language algorithm, but the modifier is too far from its noun.
Participle phrases like this one (verbING phrases) can also modify the entire preceding clause(s), but that function is not the case here.
The first error is fatal, but if you did not catch it and could not decide about but falling, you could keep this option tentatively.
ELIMINATE B
• singular one does not agree with plural are making waves
ELIMINATE C
→ correct: algorithms that have
→ correct: one of the algorithms . . . is making waves
→ The simple present it falls is consistent with the other verb tenses in the sentence
→ but in but it falls correctly signals contrast between the clauses
KEEP
• we need a contrast word: and should be but
→ the sentence describes one positive characteristic: the algorithm is "making waves"
→ the sentence also describes one negative characteristic: the algorithm "falls short" on common sense
The word and does not convey the needed contrast.
ELIMINATE E
The correct answer is D.
NOTES
• One of the Xs: Summary of the rule
I explain these rules in this post, here. Colin Kaepernick is a brave and prescient man.
The rules below will hold 99 percent of the time.
When we see one of the Xs, whether the verb that follows that phrase is singular or plural turns on whether the phrase is accompanied by THAT/WHO.
One + of + the + Xs = singular verb
One + of + the + Xs THAT/WHO = plural verb following that or who
If that or who does follow one of the Xs, then one of the Xs is plural.
→ → She is one of the students who learn Spanish and English simultaneously.
If that or who is NOT present, then one of the Xs is singular.
→ → One of the students learns Spanish and English simultaneously.
In this sentence, one of the Xs is followed by a that clause, so the verb following one of the Xs that is plural:
Correct: one of the algorithms that have been released this year

2. algorithms - Subject is plural
A) has been released last year, is making waves in the global scientific community due to its ability to mimic human writing, but it falls
S-V Error as highlighted
B) has been released last year, is making waves in the global scientific community because of its ability to mimic human writing, but falling
S-V Error as highlighted
C) has been released last year, are making waves in the global scientific community having the ability to mimic human writing, but it falls
S-V Error as highlighted
D) have been released last year, is making waves in the global scientific community for its ability to mimic human writing, but it falls
Perfect - No Remarks
E) have been released last year, are making waves in the global scientific community because of its ability to mimic human writing, and falls
