The subject of the lesson says subjunctif présent always follows vouloir que. If the sentence is in the past "elle a voulu que"' what happens to the subjunctive? Is it really in the present "elle a voulu que le chien parte" or should the subjunctive past be used? "'elle a voulu que le chien soit parti."'

Please could someone explain the use of "se tenir debut" to mean "stood" in the first example? 

Thanks

Question today was "Un jour, on _____ sur Mars."  In a previous   test, "On a ______ opinion."  The previous answer was "On a notre opinion," but today's test was said to be "On ira sur Mars."  How is one to know if the "on" refers to a singular person (on ira) or to several individuals (On a notre opinion)?  It's a bit confusing.  Please clarify.  Thanks.

Bonjour Madame, 

A sentence from the lesson states -  

Nous nous l'imaginons blonde aux yeux bleus. 

Could “aux yeux bleus” be replaced with “y” as and be correct -

Nous nous l’y imaginons blonde. ? 

Merci beaucoup !

In this sentence:

Quand vous voyagerez en France, vous serez très occupé.

should 'occupé' be 'occupés' to agree with the plural 'vous?'

Thank you!
