Not very convinced with the OA. The placement of “roughly” in E can also be construed to be ambiguous (modifying sits) or (at eyebrow level).

Had the adverb “roughly” been inserted after “at eyebrow level” in E, then we would have a clear meaning.

Thoughts AndrewN?

Hello, Ravi. I think the sentence could benefit from either the addition or deletion of a comma, specifically around the prepositional phrase. Either change would add clarity to the sentence.

1) Google Glass is basically a small computer, with a camera and a display screen above the wearer’s right eye, and sits

2) Google Glass is basically a small computer with a camera and a display screen above the wearer’s right eye and sits

In the first sentence, the extra comma denotes that the phrase is non-essential, more or less interrupting the main clause; in the second, which I think would cause students a little more trouble (who might want to call the sentence a run-on), the lack of commas marks the phrase as essential, and the two parallel parts follow a somewhat different construct: is something and sits. But with a single comma, the sentence is left open to interpretation (and criticism).
