Since conscious patients often died of shock on the operating table, the invention of anesthesia was essential to the development of surgery as the invention of the propeller was to powered flight.

(A) the invention of anesthesia was essential to the development of surgery as the invention of the propeller was to powered flight
(B) inventing anesthesia was as essential for the development of surgery as the invention of the propeller was for powered flight
(C) the invention of anesthesia was as essential in the development of surgery much as the invention of the propeller had been for powered flight
(D) the invention of anesthesia was as essential to the development of surgery as the invention of the propeller was to powered flight
(E) the invention of anesthesia was essential to the development of surgery, so was the invention of the propeller essential to powered flight

how to decide between A and D

Idiom: as X as Y

In option A, as is missing. It should be as X as Y

Hi All,

Yes, the correct answer is D. Sparkles3144 caught the overall parallelism:

the 2-part parallelism is:

"the invention....was AS essential to the development......AS the invention of the propeller was to powered...."


As you all continue to practice, be on the look out for this type of 2-part parallelism; it will show up at least a couple of times on Test Day.
