Answer:
Hacia adelante.
Step-by-step explanation:
It is a bit difficult to translate the expresion "straight ahead" in Spanish. However, the meaning of the expresion is more or less "hacia adelante".
We can see that in the following context:
-She looked straight ahead in order to avoid eye contact with him.
-Ella miraba hacia adelante para evitar contacto visual conmigo.
Besides the Spanish word "todo" has another kind of meaning:
-Todo está limpio.
-Everything is clean.
As you can see "todo" means "everything".
