Problem: Bermuda:

In 1610, all but three of the survivors of the Sea Venture sailed on to Jamestown. Among them was John Rolfe, whose wife and child died and were buried in Bermuda. Later in Jamestown he married Pocahontas, a daughter of the powerful Powhatan, leader of a large confederation of about 30 Algonquian-speaking tribes in coastal Virginia. In 1612, the English began intentional settlement of Bermuda with the arrival of the ship Plough. St. George's was settled that year and designated as Bermuda's first capital. It is the oldest continually inhabited English town in the New World.

Problem: Israel:

The most catastrophic earthquakes we know of occurred in 31 BCE, 363, 749, and 1033 CE, that is every ca. 400 years on average. Destructive earthquakes leading to serious loss of life strike about every 80 years. While stringent construction regulations are currently in place and recently built structures are earthquake-safe, as of 2007[update] the majority of the buildings in Israel were older than these regulations and many public buildings as well as 50,000 residential buildings did not meet the new standards and were "expected to collapse" if exposed to a strong quake. Given the fragile political situation of the Middle East region and the presence there of major holy sites, a quake reaching magnitude 7 on the Richter scale could have dire consequences for world peace.

How often do earthquakes that lead to serious loss of life occur?
---
A: every 80 years

Seasonal rankings (based on average total viewers per episode) of American Idol. It holds the distinction of having the longest winning streak in the Nielsen annual television ratings; it became the highest-rated of all television programs in the United States overall for an unprecedented seven consecutive years, or eight consecutive (and total) years when either its performance or result show was ranked number one overall.

How many consecutive years was American Idol the top rated show?

A: seven


Problem: Electric motor:

The first commutator DC electric motor capable of turning machinery was invented by the British scientist William Sturgeon in 1832. Following Sturgeon's work, a commutator-type direct-current electric motor made with the intention of commercial use was built by the American inventor Thomas Davenport, which he patented in 1837. The motors ran at up to 600 revolutions per minute, and powered machine tools and a printing press. Due to the high cost of primary battery power, the motors were commercially unsuccessful and Davenport went bankrupt. Several inventors followed Sturgeon in the development of DC motors but all encountered the same battery power cost issues. No electricity distribution had been developed at the time. Like Sturgeon's motor, there was no practical commercial market for these motors.

 Which inventor never went bankrupt?
