D is the answer.

Sentence can be split into two parts:-
1. "Artificial intelligence will soon become more effective than humans at even the most highly skilled jobs, including engineering, computer programming, marketing,"
2. "and waiting to consider its impact on the labor market could have catastrophic consequences."

Now it is easier to figure out issues in given answer choices, as mentioned below:-

A. including engineering, computer programming, marketing, and waiting to consider its
Wrong - need 'and' before 'marketing'.

B. including engineering, computer programming, marketing, and waiting to consider their
Wrong - need 'and' before 'marketing'. Also 'their' is wrong for singular antecedent 'AI' (main subject).

C. such as those of engineering, computer programming, and marketing, and waiting to consider their
Wrong
-'their' is wrong for singular antecedent 'AI' (main subject).

D. including engineering, computer programming, and marketing, and waiting to consider its

E. such as engineering, computer programming, marketing, and waiting to consider its
Wrong - need 'and' before 'marketing'.

VERITAS PREP OFFICIAL EXPLANATION:



This problem brings up a critically important strategic point: perhaps your greatest advantage on Sentence Correction problems is you get to determine the order in which you make decisions! Trying to make your decisions from left to right here can be difficult: do you choose "including" or "such as"? This is a classic "false decision point" - either would work well (in fact "such as" in this context really just means "including"). You'd be making an arbitrary decision that might very well eliminate the correct answer.

But if you start from the right-hand side you will see a very actionable pronoun decision available to you: "Its" vs. "their." The pronoun should refer to "artificial intelligence" (waiting to consider artificial intelligence's impact on the labor market could have catastrophic consequences; could you really say the same for "highly skilled jobs"?), so the correct pronoun must be "its." You can now eliminate choices (B) and (C).

Among the remaining choices, resist the urge to see a list of items all ending in -ing and reflexively place the "comma + and" before the last item: the meaning of the sentence matters! Is "waiting to consider" a highly-skilled job like "engineering" and "computer programming"? Of course not. The list of "highly-skilled jobs" has three items (engineering, computer programming, and marketing) so you need a "comma + and" before "marketing."

From there, "waiting to consider" is a separate part of the sentence, which when you cut out the modifier ("including these jobs") says more succinctly "artificial intelligence will soon become more effective than humans at even the most highly-skilled jobs, and waiting to consider it's impact on the labor market could have catastrophic consequences." Choice (D) is the only one that properly accounts for the list nested in the modifier and for this necessary sentence structure, and is therefore correct.

Note also that if you were between (A), (D), and (E), the only difference between (A) and (E) is immaterial ("including" vs. "such as"), and that should encourage you to more closely consider the rationale for a strange-looking "list" in (D).
