En un laboratorio, el cabello largo debe estar sujeto para evitar riesgos como incendios o contaminación. "Held away with one hand" no es seguro (la mano se necesita para el experimento). "Cut short" no es necesario, ya que se puede sujetar. "Always neatly groomed" no se refiere a la seguridad en el laboratorio. La opción correcta es sujetarlo con bandas, alfileres, etc.
