So the difference between cuál/cuáles and el cual/la cual/los cuales/las cuales is that cuál and cuáles are not preceded by articles and will only be used in questions, whereas el cual/la cual/los cuales/las cuales are preceded by articles and will not be used in questions?

Is it because despierta is being used as an adjective here? Thank you

When I hear the phrase "la falda es bonita", it sounds like "la fine-da ...". I would expect to hear something like "foul-da". Do you agree? I have to admit it has taken me years and a pair of good hearing aids to make progress with hearing Spanish pronunciation. Thank you for your excellent Spanish learning application!

please, help to understand why when I am using formal question

tiene un boligrafo is correct but

tiene usted un boligrafo marked as incorrect

En este frase, no entiendo por que es "Si usted hubiera venido antes, yo le atendería" y no "Si usted hubiera venido antes, yo le habria atendido".  No entiendo por que la tradución en ingles es I would have served you y no I would serve you.... Help!
