Premise: The Taro (Latin "Tarus") is a river in Emilia-Romagna, in northern Italy. It is a tributary of the Po and is 126 km long. It flows almost entirely in the province of Parma, west of the city Parma. The Taro flows into the Po near Gramignazzo, a frazione of the comune of Sissa, north of Parma.
Hypothesis: The Taro flows almost entirely in the province of Sicily.
