Choose the phrase that best fills in the blank. Nous (revenir) de Prague hier soir.

Revenir forms the passé composé with être: nous sommes revenu. Because the subject is nous, the past participle agrees with it; for a masculine or mixed group, revenu takes an -s, giving « nous sommes revenus ». So the completed sentence is « Nous sommes revenus de Prague hier soir » (We came back from Prague last night).
