Question

1. marta busca el salón de belleza que no (cerrar) al mediodía. cierre

Explanation:

This is a Spanish grammar question requiring the correct subjunctive form. The sentence uses "que" to introduce a relative clause describing a desired salon, so the subjunctive mood is needed. The third-person singular present subjunctive of "cerrar" is "cierre", which is the correct form here.

Answer:

cierre
