¿qué miró el público? ( los representaciones y las obras teatrales)

There is no context about this exercise, so I guess you want to answer the question:

"¿Qué miró el público?"

which means "What the audience look at?"

The answer should be " (los representaciones y las obras teatrales)"

(here you can notices that "representaciones" is a feminine word, and "Los" is a masculine pronoun, so the correct way to write this is "Las representaciones y las obras teatrales")

This can be translated to: "The representations and the plays"

So we have:

-What the audience look at?

-The representations and the plays
