Answer 1

2. . My sisters _______ to school every day. *

A) don't walk ✅

B) don't walks

C) doesn't walk

D) didn't walk

Explicación:

PRESENTE SIMPLE - NEGATIVO

El sujeto es 'My sisters' que significaría 'Mis hermanas' y su pronombre personal sería THEY (Ellos, ellas).

Entonces, para los pronombres I, you, we y they; no se conjuga al verbo, simplemente se queda en infinitivo y añadimos un auxiliar don't (= do not) para estos pronombres.
