En el diagrama de Venn de la Escuela A, los estudiantes que no hacen ni看电视 ni usar Internet son 0 (ya que no hay nada fuera de los círculos).
Step2: Calcular estudiantes que no hacen ninguna actividad en B
En la tabla de dos - vías de la Escuela B, los estudiantes que no usan Internet y no ven televisión son 4.
Step3: Comparar
Como 4 > 0, más estudiantes no hacen ninguna actividad en B que en A.
