Final answer:
Two sentences that support the claim of growing support for single-gender education are the increase in single-gender public schools and classrooms, and a retired family physician becoming an ardent proponent after dedicated study. b is the correct answer.
Step-by-step explanation:
The question asks which two sentences from Passage 2 support the author's claim that more and more people support single-gender education. The correct options in the final answer that demonstrate this increasing support are:
Option b: "Today, there are about 120 single-gender public schools and more than 380 schools that offer single-gender classrooms."
- Option d: "But after visiting hundreds of schools and dedicating recent years to studying the benefits of single-gender classrooms, he is now an ardent proponent."
These statements indicate a growth in the number of single-gender schools and a change in attitude of a noted individual towards single-gender education, respectively, thereby supporting the author's claim.
