Answer

Explanation:

Step1: Analizar datos de banda

Número de estudiantes de séptimo grado que prefieren banda = 12. Número de estudiantes de octavo grado que prefieren banda = 6.

Step2: Analizar datos de teatro

Número de estudiantes de séptimo grado que prefieren teatro = 8. Número de estudiantes de octavo grado que prefieren teatro = 14.

Step3: Analizar datos de arte

Número de estudiantes de séptimo grado que prefieren arte = 20. Número de estudiantes de octavo grado que prefieren arte = 20.

Step4: Evaluar opciones

  • Opción A: Número de estudiantes de octavo grado que prefieren arte (20) es más que los que prefieren banda (6) o teatro (14).
  • Opción B: Número de estudiantes de séptimo grado que prefieren banda (12) + teatro (8) = 20, que es igual al número de estudiantes de séptimo grado que prefieren arte (20), no menor.
  • Opción C: Número de estudiantes de séptimo grado que prefieren teatro (8) no es la mitad de los estudiantes de octavo grado que prefieren teatro (14).
  • Opción D: Número de estudiantes de séptimo grado que prefieren banda (12) no es el doble de los estudiantes de octavo grado que prefieren banda (6).

Answer:

A. More eighth - grade students prefer art as an elective than prefer band or theater.
