What is the difference between deber in El pretérito indefinido + El infinitivo (compuesto) and deber in El condicional simple + El infinitivo compuesto? Both lessons say they mean Should have 

One of my answers is “No me apetece un bocadillo ni un burrito”.

According to the corrector, this answer is wrong.

I do not understand because in the explanations, there is a note which reads as follows:

“We sometimes omit the first “ni” and only use the “ni” in the second element of the sentence with a verb in negative”

Hi, I know someone asked this question earlier, but still this "ya que" bugs me.

There must be some kind of difference in choosing between "ya que" and "porque".  

Can you help me understand when to use which?  

Thank you!

Put a coat on, Carlitos! Do YOU think it's August?

¡Ponte un abrigo, Carlitos! Ni que estuviéramos en agosto.

Why “estuviéramos” and not “estuvieras”?

I wondered what was meant here in the English?

Él estuvo en su equipo de fútbol.
He was on his football team.

Thanks

In the example La pájaro vuela sobre tu cabeza, why is it "tu" cabeza. I thought when talking about body parts and clothing we should use the definite articles rather than the possessive adjectives.  

I would like to ask how they are related and if one can be used instead of the other one
