My go-to dictionary, Word Reference, gives 'tout l’ensemble’ and 'somme toute' as translations.  One of the acceptable translations was 'en somme', which is close to what WR used.  However, 'tout l’ensemble', which is what I chose, was not accepted.   Should it be added?

There are two examples of the verb, s'avérer, in this exercise:

1)  Et les compétences que j'ai acquises comme avocate se sont avérées inestimables dans ce nouveau domaine.

2)  Ce changement se sera avéré être la meilleure chose que tu aies jamais faite.

My dictionary translates s'avérer as "prove to be" or "turn out to be".  In the second example, the infinitive être is added to s'avérer whereas in the first it is absent.  Is être optional?  If the 'to be' is included in the definition, why is être necessary in the second example?

Elsa gave her little brother his toy back. -> Kwiziq answer

Could this also be translated as "Elsa gave her toy back to her little brother"? How do you know who the toy belongs to?

Thanks
