respuesta:
Barbara usually cooks dinner for her husband after work.
This week Barbara is away on business, so Tom is cooking dinner for himself.
At the moment, my parents are on vacation, so they are eating breakfast much later.
explicacion:
In the first sentence, "usually" suggests a habitual action, and since "Barbara" is a singular third-person subject, the correct verb form is "cooks" (present simple, third person singular).
In the second sentence, "This week" suggests a temporary action, and "Tom" is the singular third-person subject. Therefore, the correct verb form is "is cooking" (present continuous, third person singular).
In the third sentence, "At the moment" suggests a current action, and "my parents" is a plural third-person subject. Therefore, the correct verb form is "are eating" (present continuous, third person plural).
