Suppose Pisa is a city in Tuscany, central Italy, straddling the River Arno just before it empties into the Tyrrhenian Sea. It is the capital city of the Province of Pisa. The city is known worldwide for its leaning tower, the bell tower of the city's cathedral.
Can we infer that "Pisa is the only city in Tuscany that has a leaning tower"? Yes, no, or maybe?
