Answer: Las horas de trabajo
Explanation: The sentence is:
" Entro a trabajar a las ocho y media de la mañana, salgo a las dos y media de la tarde"
That can be translated to:
"I start work at 8:30 of the morning, and I finis at 2:30 in the afternoon"
The question is: What does the following description refer to?
The options are:
Salario (salary)
La hora del almuerzo (lunchtime)
el trabajo en equipo (teamwork)
Las horas trabajadas ( The worked hours)
The sentence clearly tell us information about the worked hours (from 8:30 am to 2:30 pm), so the right answer would be the fourth one, "las horas trabajadas"
