Answer 1

Respuesta:

d.

Mark was reading a psychology book while the policemen were looking a thief.

Explicación:

a. No es porque para past pogressive usamos was/were y ahí esta usando are

b.  No es poque la primera idea no cumple con la estructura  was/were+ verbo en ing , teniendo el verbo en su forma simple ( read)

c. No es porque una acción está en presente (is)  y otra en pasado(were)  pero la oración indica que ambas sucedieron al mismo tiempo con while

d. Sí es porque las dos acciones están expresados en el mismo tiempo gramatical usando was y were + el verbo en ing  y se mantiene la simultaniead con respecto al while (mientras)
