The underlined portion includes the verb have traced , so check for subject-verb agreement. The subject is historians , so the plural verb have traced is correct. (The prepositional phrase "of film" ends in a singular noun to trick you into thinking that the verb should be singular.) The i...

While it is true that choice E lacks the serial ("Oxford") comma between the parallel items in the list, in my experience the GMAT will never make such a fine point the SOLE reason for eliminating an answer choice. There must be a more substantial reason for eliminating the answer choice. ...

The entire sentence is underlined (or should be). That means both subject and verb are underlined, so check that they agree.

I would probably take the "brute force" approach here and map it out carefully using cross-hatches. Why? Because in a question where the street count is only 30, it doesn't really take any more time to do it using the brute force method than by applying mathematical principles. I did this ...
