comme j'aime les chats, j'ai particulièrement apprécié cet exercice. au moment où j'écris, mon chat dort au soleil sur son lit, où elle restera jusqu'à ce qu'elle ait faim ou qu'elle veuille être caressée :)

J'ai lu trois livres dont les tiens/ les vôtres. [I read 3 books including yours.]

Is this correct? Or should it be le tien? Masculine/plural form should be used because the noun is 'les livres'? 

My question concerns the imparfait conjugation of the verb 'exister' in the sentence:

Aussi, lorsque j'ai appris qu'il existait un musée qui...

I would like to know if conjugating here in the imparfait (existait) does not imply that the museum used to exist, but no longer does.  I am inclined to want to conjugate 'exister' in present tense to get around this problem, yet I know its gramatically incorrect to do so. If someone can help, I would greatly appreciate.

Have a good day all :)

After submitting my response, no correction page appeared and I was simply presented with the next phrase or sentence.  As a result, I scored zero for my response.  You can't go backwards. This happened twice during the exercise.  On the second occurrence, I was particularly paying attention to not hitting the submit button a second time as I know this can cause skipping.  I could not figure out how to send this to your technical team instead of bothering you.
