Here is a premise:
More quintessentially Roman, on nearby Via Condotti, is the city's oldest coffee house, the 18th-century Cafe Greco popular, as you'll see from pictures, busts, and autographs, with Goethe, Byron, Baudelaire, Liszt, Casanova, and Fellini.

Here is a hypothesis:
The title of oldest coffee house in the city belongs to Roman.

Is it possible to conclude that if the premise is true, then so is the hypothesis?
yes
