Spanish language Q&A Forum

Please, what is the difference between usted, ustedes and vosotros? 

I have noticed in general that spanish speakers have different intonations at the end of sentences or part of sentences which confuse the listener and in dictations result in incorrect  punctuation. 

I got this incorrect: Translate: It is ten to nine. My answer: Son las diez meno nueve. Correct Answer: Son las nueve diez.  Isn't that 9:10, rather than what the question is asking

I feel that the translation of the sentence into English was incorrect for the tense requested and confused me. The clue was pretérito perfecto as well as the translation saw. Pretérito conjugation of ver for ellos is vieron or “saw”, but pretérito perfecto would be Han visto or “have seen”. Please don’t make it confusing for us!

I don’t see the “imperfecto” conjugation available in the drop down list….what is the correct answer!

Hasta ver este video había tenido la impresión de que exclusivamente se usa la frase "de x a x" para decir "from x to x," pero dice el narrador que las Picotas del Jerte "darán la vuelta al mundo de paladar en paladar."

¿También habría sido aceptable decir "de paladar a paladar"?

With the correct answer being:

She might know the truth

In another lesson the future simple also implies ´maybe/chance of´, right?

I learned naranja as the fruit and anaranjado/a as the color.  Obviously language can be used differently throughout the Spanish-speaking communities! Is that the case here?
