Problem: Charleston, South Carolina:

On August 31, 1886, Charleston was nearly destroyed by an earthquake. The shock was estimated to have a moment magnitude of 7.0 and a maximum Mercalli intensity of X (Extreme). It was felt as far away as Boston to the north, Chicago and Milwaukee to the northwest, as far west as New Orleans, as far south as Cuba, and as far east as Bermuda. It damaged 2,000 buildings in Charleston and caused $6 million worth of damage ($133 million in 2006 dollars), at a time when all the city's buildings were valued around $24 million ($531 million in 2006 dollars).

What was the cost of the damage of the 1886 earthquake to the city of Charleston?

A: $6 million

Problem: The investigation of the transmitted signals started immediately after the launch of Compass -M1 on 14 April 2007. Soon after in June 2007, engineers at CNES reported the spectrum and structure of the signals. A month later, researchers from Stanford University reported the complete decoding of the "I" signals components. The knowledge of the codes allowed a group of engineers at Septentrio to build the COMPASS receiver and report tracking and multipath characteristics of the "I" signals on E2 and E5B.
When did the investigation of the signals transmitted by Compass -M1 begin?
---
Answer: immediately after the launch of Compass -M1 on 14 April 2007

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Yet another influential philosopher who had an influence on modern philosophy was Ibn Tufail. His philosophical novel, Hayy ibn Yaqdha, translated into Latin as Philosophus Autodidactus in 1671, developed the themes of empiricism, tabula rasa, nature versus nurture, condition of possibility, materialism, and Molyneux's problem. European scholars and writers influenced by this novel include John Locke, Gottfried Leibniz, Melchisedech Thevenot, John Wallis, Christiaan Huygens, George Keith, Robert Barclay, the Quakers, and Samuel Hartlib.
What was Hayy ibn Yaqdha translated to in the 16th century?
A: unanswerable

Context and question: The Downtown District is the home of the Third Street Promenade, a major outdoor pedestrian-only shopping district that stretches for three blocks between Wilshire Blvd. and Broadway (not the same Broadway in downtown and south Los Angeles). Third Street is closed to vehicles for those three blocks to allow people to stroll, congregate, shop and enjoy street performers. Santa Monica Place, featuring Bloomingdale's and Nordstrom in a three-level outdoor environment, is located at the south end of the Promenade. After a period of redevelopment, the mall reopened in the fall of 2010 as a modern shopping, entertainment and dining complex with more outdoor space.
What's at the north end of the Promenade?
Answer: unanswerable

Question: The Federal War ended in 1863 with the signing of the Treaty of Coche by both the centralist government of the time and the Federal Forces. The United States of Venezuela were subsequently incorporated under a "Federation of Sovereign States" upon principles borrowed from the Articles of Confederation of the United States of America. In this Federation, each State had a "President" of its own that controlled almost every issue, even the creation of "State Armies," while the Federal Army was required to obtain presidential permission to enter any given state.
Is there an answer to this question: When did the federal war end?

Answer: 1863

Question: During the Permian all the Earth's major land masses, except portions of East Asia, were collected into a single supercontinent known as Pangaea. Pangaea straddled the equator and extended toward the poles, with a corresponding effect on ocean currents in the single great ocean (Panthalassa, the universal sea), and the Paleo-Tethys Ocean, a large ocean that was between Asia and Gondwana. The Cimmeria continent rifted away from Gondwana and drifted north to Laurasia, causing the Paleo-Tethys to shrink. A new ocean was growing on its southern end, the Tethys Ocean, an ocean that would dominate much of the Mesozoic Era. Large continental landmasses create climates with extreme variations of heat and cold ("continental climate") and monsoon conditions with highly seasonal rainfall patterns. Deserts seem to have been widespread on Pangaea.
Is there an answer to this question: What supercontinent prevailed during the Permian era?

Answer:
Pangaea
