Our school district should switch to single-gender classrooms. Which of the following supporting details provides the most relevant and
credible evidence for the claim?
A. Results from a nationwide survey show that by a wide margin both
male and female students who have experienced both mixed and
single-gender classrooms prefer single-gender.
B. The most recent vote on the single- versus mixed-gender
classroom issue saw our school board deadlocked at 3-3, and,
with the seventh member on vacation, no majority could be
achieved.
C. Studies from the National Education Board show that students
from single-gender classrooms score roughly the same on
standardized tests as students in mixed-gender classrooms.
D. My cousin Jacqueline's high school will switch to single-gender
classrooms in the fall, and she says she wouldn't be surprised if it
helped her concentration in the classroom.
