Task: Question Generation
Input (English): 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.
Output (English): How many residential buildings did not meet construction standards?
