Entro al salón y veo escritorios y sillas de madera dirigidos al pizarrón. Mis compañeros siguen hablando mientras guardan sus mochilas hasta el fondo del salón junto a la pared. Las paredes son amarillas y las ventanas grandes que tienen cortinas de color gris, y el piso es negro. La maestra entra al salón. Se ve muy cansada. Lleva una bolsa negra con libros y lápices de color. Nos grita que debemos sentarnos y estar listos para la clase de hoy, y todos vamos y tomamos asiento, listos para aprender.

I hope this helps...!

answer: the answer is b. se quejan because it's in the plural form.
