A student is writing an editorial and wants to revise the draft. Read the two paragraphs from the student's article and answer the question that follows.

The 2014 opening of the Writing Center was an enormous benefit to students at our high school. Any skepticism about the project was quelled within weeks, as workshops and open tutoring hours quickly filled up. While only anecdotal evidence is available, faculty in the English department credit the center with improved student planning, writing, and editing.

The proposed Mathematics Center would have similar offerings: drop-in hours for one-on-one tutoring, workshops, and a multi-media resource library, as well as space for study groups and group work. The benefits of such a program seem obvious, and the administration has not fully explained its reasons for delaying a decision. Students and faculty have a right to know.

Which sentence would provide the BEST transition between the two paragraphs?
-Students say that having a space to work together and focus on a single subject greatly aids understanding of the content.
-Given the success of the Writing Center, it is curious to me that the proposal for a similar Mathematics Center has had such a lukewarm reception.
-Research studies have shown that creating content-area-focused environments reaps huge rewards in terms of students' academic gains.
-A group of students and their faculty sponsors have proposed the establishment of a Mathematics Center that would be open to all students at the high school.
