The correct answer to the question "What does the following description refer to? Trabajo veinte horas semanales. Mi turno es por la mañana y en tarde estoy para estudiar" is B. trabajo a tiempo parcial.
Here's why:
1. The description mentions working twenty hours a week, which indicates part-time work rather than full-time employment.
2. It also states having a morning shift and studying in the afternoon, suggesting a schedule that accommodates both work and education, which aligns with part-time employment.
3. Working part-time allows for a balance between work and other commitments, such as studying, as mentioned in the description.
4. Therefore, the description best fits the concept of "trabajo a tiempo parcial" or part-time work rather than referring to colleagues, workplace location, salary, or an afternoon class.
By selecting "B. trabajo a tiempo parcial" as the correct answer, you are identifying the employment situation described in the text accurately.
