know whether tu or usted is required.  Could it not be either, depending on the formality, which is not stated?

A recent Kwiziq question asked: 

HINT: Conjugate "traer" in the usted form of El Presente Subjuntivo 

The correct answer was : traiga

However, I learned to ask for things by attaching the I.O.P to the end of the imperative/subjunctive, for instance: 'Tráeme una taza de café' or, more politely, 'Pongame una taza de café'. 

So I wonder if in this question 'tráiganos' might not be more appropriate, or sound more natural? 

“Maria told us there was a meeting at 4”

hubo is incorrect here, but I thought with a set time it became ‘hubo’? What am I missing? 

Why is cambiar used with the preposition de and sometimes without? Is there any difference between the two ways of using cambiar?

In the sentence:Ellas a luz a unos gemelos preciosos. (They gave birth to beautiful twins),

1) does "ellas" indicate 'several women gave birth to several sets of twins'? 

2) If a married couple had A set of twins, would that be ' ellOs a luz a un gemelo precioso?, Or does 'a luz' literally only refer to the mother who gives birth?

Thanks

I have understood that in Spain, the -se conjugation was used more in writing and formal situations, and -ra was more conversational. Is that not correct?

I’m confused between hace and hacía + time frame. Do you have a deep dive on this? Thanks

Yo fui a casa de mi abuela la semana pasada.
I went to my grandmother house last week.

Why is this not fui a la casa rather than fui a casa?
