as those charging/as charge


Senior Member
Sample multiple-choice test:
According to a 1996 survey by theNational Association of College and University Business Officers, more than three times as many independent institutions of higher education charge tuition and fees of under $8,000 a year ________ over $16,000. charge
B as those charging

My confusion:
The answer key is B in the original page, but I feel that “those charging”, which is itself a noun phrase, has no counterpart since the part after the first “as” is not a noun phrase, and thus I would go for A, as a lot think in the comment area of the original test.

What’s your idea? Hope you would help : )

    To compare this sentence "It ships more than three times as much in exports to cash-rich oil producers as America does. " and the sentence above.
