Spanish language Q&A Forum

"Aparecerás en el perfil de la búsqueda..."   "... tu disponibilidad y el país preferido..."  I included "la" with búsqueda and "el" with país, but are not used here.  I never really know when and when not  to use them.  Is there a lesson somewhere on the website about when to use the articles?  I forgot to add at the beginning when we are translating "As an au pair", the correct way is to say "Como au pair..." and again, I wrote "Como un au pair..."  This is another example of me being confused as to when and how to use the articles.

sometimes the answers come back in English instead of spanish.  How can I fix that?

In the example "A veces ________ que llevamos casados 20 años", why is simple olvido wrong? - when there was another question in another kwizz about forgetting a towel, and olvido was correct. How are we supposed to know if something is accidental or not? I must say that I find this lesson absolutely confusing and no matter what I put in the answer, it always seems to be wrong. 

(And I notice that it lists me as C1. I'm not C1, I am still struggling with B2. The Kwizbot doesn't understand the fluctuating nature of how people learn, forget, re-learn, get wrong again, and so on.)

Isn't it the same topic as "Gerundio"?

Can you use the preposition "con" after the article instead to denote posession? For example: 

-La mujer de allá es muy guapa. 

-¿Qué mujer?

-La con la blusa roja. 

Would that be correct? Thanks
