Final answer:
If boys attend an all-male school, the school remains all-male, as it continues to only admit and educate boys. It will not become co-educational or include girls unless the school's admissions policies change.
Step-by-step explanation:
If boys attend an all-male school, the school remains all-male. This means that only boys are admitted and educated there, and no girls are in attendance, keeping the institution single-gender. An all-male school would not become co-educational unless it changed its admissions policies to include female students. This type of school setup is one way that historical gender roles and stereotypes have been reinforced in the education system.
