The correct answer to this open question is the following.

Although there are no options attached, we can say the following.

The two issues that Italian Renaissance Architects solved by returning to classic architecture were the symmetry of the constructions and the proportion, returning to the classical style of the Roman Empire. Gothic structures were obscure and irregular, so the Italian Renaissance architects decided to renovate the construction style by returning to classical Roman styles, working with better symmetry and proportions that created more artistic geometric forms with an aesthetic touch.

The results of this new improved style by Renaissance artists and architects can be found in the streets of Florence, Italy, the place where the Renaissance born.
