I want to know the answer to the following question:
Which families help to start cultural, industrial, and economic growth in Palermo?
All the background I'm provided with is that "A new cultural, economic and industrial growth was spurred by several families, like the Florio, the Ducrot, the Rutelli, the Sandron, the Whitaker, the Utveggio, and others.". Is that enough to answer the question?
