Don't ask, just post your questions. Somebody will ALWAYS help you, native or  non native.

anonymous · Answer

I am. But like @Vincent-Lyon.Fr said. Post your questions ;)

anonymous · Answer

There not questions, more of checking my sentences. :P 
& hang on,

anonymous · Answer

One of my questions were, 
¿Qué fenómeno o misterio arqueológico del mundo hispano te interesa más y por qué? 

& I answered it as, 
La música, porqu este diferente a nuestro tipo de música de hoy.

anonymous · Answer

porqu(e)

anonymous · Answer

Ah my bad,

anonymous · Answer

And then, " La falta de oportunidades de empleo."

anonymous · Answer

Don't worry :)

vincent-lyon.fr · Answer

Music in not really an 'archaeological mystery'.

I would have written "porque es diferente"

anonymous · Answer

@Vincent-Lyon.Fr is right. I didn't notice you wrote "este". "La falta de oportunidades de empleo." is a sentence but how are you using it?

anonymous · Answer

Should I change the whole sentence? 

My question for that one was, "¿Qué misterio o fenómeno ha ocurrido en los Estados Unidos que es similar a uno que has estudiado del mundo hispano?"

& I answered it as "La falta de oportunidades de empleo"
