Answer:
Dinnertime
Step-by-step explanation:
After her shift, Lisa would most likely start preparing for dinnertime. To find out the answer, we need to analyze this extract.
When you start reading the text, you know that there are two shifts at Lisa's school, one in the morning and the other in the afternoon: "Mi escuela es una escuela urbana que tiene dos turnos de lunes a viernes: el turno en la mañana y el turno en la tarde". If you continue reading, you will see that Lisa's shift is in the afternoon (from 1 pm to 5 pm): "Yo voy a la escuela peruana a las trece horas y la escuela termina a las diecisiete horas de lunes a viernes". Therefore, her shift finishes at 5pm from Monday to Friday and probably at that time she will start getting ready for dinner when she arrives home.
As to the other options, lunchtime must be discarded because at 5pm when she finishes school, lunch will be over. Sports training and choir rehearsal must also be discarded because these are activities that Lisa performs on Saturday and Sunday, and she does not go to any school shift on the weekend.
