By process of elimination, I selected estuvieron as being the correct answer; however, my preference would have been estaban. 

See the example given below:

Mario estaba de camarero en un restaurante.
Mario was working as a waiter in a restaurant.

Here is the question with the answer:

Mis hijos _estuvieron_ de vendedores en una tienda.
My children were working as shop assistants in a store.

My choice:
Mis hijos _estaban_ de vendedores en una tienda.

Would you explain the reason for the answer being the preterite and not the imperfect, please.

Why is it "pero esta muy fría" instead of "pero está muy fría"?  Also, why is it "está protegida" instead of "es protegida"?

Hola,

In the explanation for the following sentence, it's mentioned that one of the subjunctive possibilities is that it might snow later:

Aunque esté nevando, voy a sacar al perro a pasear.

My question is: because we are using nevando, rather than nieva - is that not telling us it is snowing right now (present participle), and therefore can't be a future event?

So, the only possibility is that it is subjunctive because it is shared information that it is snowing right now?

Gracias,

I had never heard that before.So, I can retract my question. 

Could you also say “Me había regalado un esqueje”?
