Magoosh Official Explanation
A. No. Idiom: "a is to b what y was to z."
Also, subject-verb agreement ("dictation and a stenographer" are plural and should go with "were," not "was").
B. No. Idiom: "a is to b what y was to z."
Also, verb tense. You should use the simple past because the "former time" is over.
C. Yes. The correct idiom is: "a is to b what y was to z."
D. No. Subject-verb agreement ("dictation and a stenographer" should go with "are" not "is," except the correct tense would be "were").
E. No. Idiom: "a is to b what y was to z."
Aside from a botched idiom, in the comparison, like should be as. See Notes, below.The best answer is C.• My notes-- IDIOM: A is to B what Y was to Z
The pattern in this idiom makes it fairly easy to spot.
This idiom may seem rather obscure, but you would be surprised to discover how frequently it turns up in formal writing.
Do not memorize it.
You have now read about it a couple of times.
Because this idiom is almost mathematical (as if we were comparing two ratios), I suspect that you will recognize it when you see it from now on.-- LIKE vs AS
Please see my explanation of the difference between like and as in this post, here.
One shortcut I discuss is that in comparisons, like must never be followed by a verb, whereas as is almost always followed by a verb.Correct:
Like bergamot, cilantro tastes soapy to some people. [No verb coupled with "like."]
Correct:
Just as bergamot tastes soapy to some people, so too does cilantro. [A verb IS coupled with "as."]
Keep up the good work, everyone.
