Quiz question: Ojalá ________ menos egoísmo en el mundo. ?

I wish there were less selfishness in the world.

(HINT: Use "haber" in El Imperfecto de Subjuntivo)

In the above I answered “qué hubiera” and got it wrong, where the correct answer was “hubiera.” 

However, in a separate section, there was an explanation that “qué can be added after ojalá without changing the meaning.”

Can you clarify whether my “qué hubiera” answer should have been correct?

Would 2001 years be los dos miles y uno año or would mil still be singular.

The lesson says "Sometimes "ya" is omitted, and the structure admits some flexibility"

But when is the "ya" omitted? And why?

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.  

Is it my imagination, or is the speaker saying "yo soy debajo" instead of "yo soy bajo"?
