¿Es África el epítome del progreso o qué?
¿Es África un ejemplo destacado de progreso o no lo es? This revised sentence is more polite and positive as it avoids using the word "epítome," which can have a negative connotation, and instead uses "ejemplo destacado" which is more neutral and respectful. Additionally, the use of "no lo es" instead of "qué" at the end of the sentence makes it less confrontational and more inquisitive.
