The clue was in the hint = 'which' refers to 'le territoire".

Is it possible to use "grâce à quoi" without this clue ? I didn't pay attention to the clue below the sentence and my 1st thought (and the answer as well) was "grâce à quoi". I wonder if it also makes a sense here ?

I make up the following, but I can't find the answers online. Are "moi" and "toi" correct here? If yes, is there an explanation why "me" and "te" are not used here?

Give it to me! = Donne le moi!

Give it to you? = Donne le toi?

Give it to him/her! = Donne le lui!

Give it to us! = Donne le nous!

Give it to them! = Donne le leur!

Can we say aux agents de bord instead of avec les agents de bord?

The question asked for the correct version translated with despite not in spite but this is still labeled correct. I'm confused.

The lesson gives two answers, one with "aussi" and "plein d' ", and one with "également" and "beaucoup".  The final text uses "aussi" and "beaucoup": "Je mange aussi beaucoup d'abricots." 

So, is it ok to match aussi/également with plein d'/beaucoup and vice versa?

Which is right and why?
