Sanity check on a SC question.

"Twenty percent of the teachers report that the new curriculum is working no better than the previous one, more than half report noticeable benefits generated by the change, and the change has not affected the remaining about thirty percent of the teachers."

We can say the remaining about thirty percent in the English language? The remaining about number?

I know what the answer to the question is - I just wanted to ask about the specific point. Here are answers for you to look at anyway.

A: More than half report noticeable benefits generated by the change, and the change has not affected the remaining about thirty percent of the teachers.

B: More than half reports that the change has generated noticeable benefits and that the change has not affected the remaining about thirty percent of them.

C: The report by more than half is that the change has generated multiple benefits, the change not affecting the remaining about thirty percent of teachers.

D: More than half report that changing generates noticeable benefits, with the remaining about thirty percent of them not affected by the change

E: More than half reports that, by changing, noticeable benefits have been generated, and the remaining about thirty percent have not been affected by the change.
