In the phrase, "curieuses boîtes", how do you know to place curieuses before the noun.

Thanks

Why are we adding de in front of  mieux in the sentence il n’y a rien de mieux  que d’’ouvrir..... 

« Combien d’enfants avez-vous? »

Can’t figure out why this is right. Enfants is plural.

Wouldn’t you say « J’ai des enfants. »

"Avez-vous ton crayon?"  This sentence here mixes a formal (or plural) pronoun with a familiar possessive adjective, which doesn't feel correct.  Could I get  confirmation that "ton, ta, tes" works for whomever is directly spoken to? 

One of the translations in the quiz was 'Everybody wants to do their best'. This may be in common usage now but correctly, I think, it should be 'his/her' best. Here 'everybody' is singular hence the singular verb 'wants', so the pronoun needs to correspond to the noun as well as the verb.

"Descendre de" rule

This may have a simple answer, but if 'de' becomes du or des when followed by le or les, why would the correct response on the quiz be: Elle descend de l'avion rather than Elle descend du l'avion?

I've re-read the lesson on when to use "d'autres" and "des autres" and I don't quite understand why "the taste of others" is "le goût des autres". I thought that would only be the case if it was specific other people "the taste of the others", and in the case of this film title it should be "le goût d'autres" - a general case of the taste of unspecified others. What am I missing here please? 

OK so I selected "Elle va revenir dans cinq minutes" as in she is going to come back in 5 minutes.

However the correct answer was "Elle revient dans cinq minutes".

Are these not both correct, I mean apart from being word perfect?
