Lolita está en el comedor. es la una en la tarde y la alfombra está sucia. what can lolita's mom tell her to do before lunch? tienes que cortar la grama y limpiar el mueble. tiene que fregar el piso y doblar la ropa. tiene que barrer y hacer la cama. tienes que pasar la aspiradora y poner la mesa.

The answer is your fourth option: Tienes que pasar la aspiradora y poner la mesa.

Explanation:

We have three key words here: comedor (living room) and alfombra sucia (dirty rug). With these two key words we can infer that Lolita needs to vacuum the dirty rug (pasar la aspiradora) and also set the table (poner la mesa), as they're about to eat lunch. The other options have nothing to do with dirty rugs or living rooms and lunch. The first option has the words clean and grass, the second option fold and wash. The third option sweep and do the bed. As you can see, looking for key words help you understand better the context and come up easier with an answer.
