Can they be used synonymously? What is the difference in meaning and use between the two?

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

The question

________ a vuestra pregunta.I am answering your question.HINT: Conjugate "contestar" in El Presente Continuo.

I understand the answer Estoy contestando buy why is the preposition "a" included in the original sentence. "Vuestra pregunta" is not a person. Estoy contestando a vuestra amiga

In the question, How would you say "There was an accident on the motorway" the nearest correct answer I can find is "Había un accidente...", and there isn't the option for preterite 'hubo'. However, because accidents are one time actions with clear beginnings and ends, it's more appropriate to use the preterite tense in this case. In fact, this particular sentence is a very common one to use when explaining the differences between the two conjugations and especially to illustrate why imperfect simply doesn't work here. 

Please explain 'al' in Mis amigos sintieron una gran alegría al verme.

Gracias,

Ricky

I wonder if there is an error in this question:

Este hotel, ________ inauguración fue ayer, va a recibir muchos turistas alemanes.

I think that the answer should be cuyo (because hotel is a masculine noun), but the Kwiziq answer on the test question is cuya.  Is this a mistake on Kwiziq's part, or am I not understanding something?
