Official Explanation
While Leonardo da Vinci is most often recognized for his artistic talents, as both an accomplished painter as well as drafting numerous sketches and the famed Vitruvian Man, he also designed plans for a flying machine, a double-hulled ship, and concentrated solar power before the technology even existed to make their creation possible.
A. as well as drafting numerous sketches and the famed Vitruvian Man, he also designed
B. as well as a draftsman of numerous sketches and the famed Vitruvian Man, he had also designed
C. and as a draftsman of numerous sketches and the famed Vitruvian Man, also designing
D. and drafting numerous sketches and the famed Vitruvian Man, also designing
E. and a draftsman of numerous sketches and the famed Vitruvian Man, he also designed
After a quick glance over the options, we have 3 main differences we can focus on:
1. as well as / and (Idioms)
2. drafting / a draftsman of (Parallel Structure)
3. he also designed / he had also designed / also designing (Construction & Verb Choice)
Let’s start with #1 on our list because it’s an either/or split. No matter which direction we go in, we’ll eliminate 2-3 options rather quickly. This is an idiom issue, and the idiom we’re dealing with is:
Both X and Y
We need to eliminate any options that don’t follow this format:
A. as well as drafting numerous sketches and the famed Vitruvian Man, he also designed
B. as well as a draftsman of numerous sketches and the famed Vitruvian Man, he had also designed
C. and as a draftsman of numerous sketches and the famed Vitruvian Man, also designing
D. and drafting numerous sketches and the famed Vitruvian Man, also designing
E. and a draftsman of numerous sketches and the famed Vitruvian Man, he also designed
We can eliminate options A & B because “both X as well as Y” is not idiomatically correct. Now that we have it narrowed down a bit, let’s tackle the next item on our list: Parallel Structure. We need to make sure the X and Y in the “both X and Y” idiom are parallel in kind. To make problems easier to spot, let’s add in the first half of the idiom, “both an accomplished painter.”
C. both an accomplished painter and as a draftsman of numerous sketches and the famed Vitruvian Man, also designing
This is INCORRECT because the two items aren’t written using parallel structure. This sentence is structured “both X and as Y,” which isn’t correct. If the word “as” had been after the word “both,” this would have been correct: “both as X and as Y.” Since it’s not, let’s rule this one out.
D. both an accomplished painter and drafting numerous sketches and the famed Vitruvian Man, also designing
This is INCORRECT because the two items aren’t parallel: “an accomplished painter” is a job title, and “drafting” is an action.
E. both an accomplished painter and a draftsman of numerous sketches and the famed Vitruvian Man, he also designed
This is CORRECT! Both items are job titles, and both items are written using parallel structure!
There you have it – option E is our winner! By focusing on either/or splits first, we were able to eliminate 4 out of 5 options without having to deal #3 on our list (which is a bit more complex).
