The question (with no other information provided) is "Drive safely!.  One of the options is "Conducir con cuidado".There is another lesson on Requests / Commands / instructions where if I have got it right the infinitive is used without the preopisiton "a"..  Why doies it not work in this instance?

Why is the answer documental not documentario?

I have just started learning about Preterito indefinido and found that one question in the test  required a preterito imperfecto answer which I have not yet learned. It is rather confusing .

Hola,

In the above phrase, could 'duchar' be used and what would the difference be in meaning?

Gracias y saludos.

fui a malaga por/en avion

Do both of these work? 

I always thought ´por´ was correct/more used?

There was a test question that said ´8 a 10´ means the same thing as ´8 menos 10´ but this guide doesn´t mention it.

Are they interchangeable?

Your explanation says that whole hundreds AFTER 200 agree with the noun it precedes, but doesn´t 100 also?

I.e. hay cientas diez chicas?

If not what would be the correct answer?

¡Hola! Leí una página que indica que "a menos de que" es un dequeísmo y no es correcto (aunque si lo uso, se entiende). ¿Es así? ¿O hay una diferencia entre los dos que depende en lo que viene antes y después? Y sea lo que sea, eso se aplica a otros tal como "con tal de que," "antes de que," y "después de que?" 

Is there a difference between using ´en´ and ´por´.

For example ´voy a hacerlo por/en la mañana´?
