Answer 1

B). by hiring more teachers and increasing funding for textbooks and other supplies, others insist that doing so.

Step-by-step explanation:

As per the question, option B best revises the underlined phrase appropriately it follows a parallel structure that assists in portraying the ideas more clearly and effectively. The parallel construction in the sentence is reflected by the appropriate use of verb phrases in an aligned manner('by hiring..teachers...increasing funding...textbooks...supplies').

The other options fail to offer a parallel structure. Options A, C, and E are incorrect as they involve noun phrases instead of verb clause while option D is wrong due to the use of inappropriate pronoun 'this' after 'doing'. Thus, option B is the correct answer.
