Dear Friends,

Here is a detailed explanation to this question-



A: This answer choice uses the plural verb "are" to refer to the singular noun "one teacher". A also utilizes the idiomatically incorrect construction "as many than", rather than the correct construction "as many as". Thus, this answer choice is incorrect.

B: This answer choice repeats the pronoun error seen in Option A. Thus, this answer choice is incorrect.

C: This answer choice repeats the idiom error seen in Option A. C also uses the singular verb "was" to refer to multiple teachers. Thus, this answer choice is incorrect.

D: This answer choice is needlessly wordy due to the use of the phrase "but that ratio is". D also changes the meaning of the sentence by using the conjunction "but", which introduces a sense of contrast. Thus, this answer choice is incorrect.

E: This answer choice conveys the intended meaning of the sentence, is concise, and maintains proper pronoun and idiom use. Thus, this answer choice is correct.

Hence, E is the best answer choice.

All the best!
