Elige una opción para comprobar tu respuesta.

Ver respuesta

Respuesta correcta: B) will be collecting

  • A) will holdIncorrect. Correct for a future event.

💡 Explicación

El Futuro Continuo (will be collecting) describiría la acción mientras ocurre. Como el contexto habla del resultado al finalizar el evento, se requiere el Futuro Perfecto (will have collected).
