The city has considered various solutions, such as demolishing abandoned homes and buildings; removing street lighting from large portions of the city; and encouraging the small population in certain areas to move to more populated locations.

Could you please come up with a good question for the passage "The FBI director is responsible for the day-to-day operations at the FBI. Along with his deputies, the director makes sure cases and operations are handled correctly.

Problem: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "North Carolina averages fewer than 20 tornadoes per year, many of them produced by hurricanes or tropical storms along the coastal plain. Tornadoes from thunderstorms are a risk, especially in the eastern part of the state. The western Piedmont is often protected by the mountains, which tend to break up storms as they try to cross over; the storms will often re-form farther east. Also a weather phenomenon known as "cold air damming" often occurs in the northwestern part of the state, which can also weaken storms but can also lead to major ice events in winter."?

A:
The things experienced fewer than 20 times per year can be caused by things from?
