Hi, All. This question is from Kaplan 800. I could easily recognize the modifier error this question is testing. However, I got confused between option B and C. any suggestion why one should be preffered over another

Pretty simple question to answer: Compare what is comparable.

From the first part of the sentence, "In addition to providing more course offerings than Willow High School'', we can tell that "Willow High School" is the first element of the comparison. So we expect the second element of the comparison to be "Menlo High School", NOT "Menlo High School teachers" as is the case in (C).

By the way, (C) is also wrong for a different reason: "than they are" make it sound like Menlo High School teachers are also teachers a Willow.

Teachers don't have course offerings; schools do. Therefore, the comparison is between Willow High School and Menlo High School. Also, the entire first part of the section is a modifier, and again, since schools offer courses, that modifier should go next to what it logically modifies: Menlo High School, not Menlo High School teachers.
In choice C, "they" is also a pronoun without a clear antecedent; logically, it doesn't make sense for it to refer to the Menlo High School teachers, but the only possible plural antecedents in that choice are those teachers or "course offerings," neither of which is actually what is being discussed. B eliminates that problem by using the demonstrative "those at Willow," which makes the reference clear.
