Answer 1

I believe it is answer A

Answer 2

Venice acquired the nearby cities of Verona and Padua using its army, which attacked the cities and gained power in only days.

When Milanese forces felt threatened by Carraras' Paduan forces; they wisely offered  Vicenza and Verona to Venice if Venice committed stopping Carraras' Paduan forces advances to the westward.    

When Venice was offered this, Venetians took advantage of the situation and using its army captured Padua in November 1404 following a brief siege. And after the chief of Carraras' family and his son were executed (Francesco and Jacopo Carrara), in a stroke Venetians eliminated completely  Carraras' forces and extended their mainland territory to include Padua, Vicenza, and Verona.
