Problem: Strasbourg:

In 1919, following the Treaty of Versailles, the city was restituted to France in accordance with U.S. President Woodrow Wilson's "Fourteen Points" without a referendum. The date of the assignment was retroactively established on Armistice Day. It is doubtful whether a referendum in Strasbourg would have ended in France's favour since the political parties striving for an autonomous Alsace or a connection to France accounted only for a small proportion of votes in the last Reichstag as well as in the local elections. The Alsatian autonomists who were pro French had won many votes in the more rural parts of the region and other towns since the annexation of the region by Germany in 1871. The movement started with the first election for the Reichstag; those elected were called "les députés protestataires", and until the fall of Bismarck in 1890, they were the only deputies elected by the Alsatians to the German parliament demanding the return of those territories to France. At the last Reichstag election in Strasbourg and its periphery, the clear winners were the Social Democrats; the city was the administrative capital of the region, was inhabited by many Germans appointed by the central government in Berlin and its flourishing economy attracted many Germans. This could explain the difference between the rural vote and the one in Strasbourg. After the war, many Germans left Strasbourg and went back to Germany; some of them were denounced by the locals or expelled by the newly appointed authorities. The Saverne Affair was vivid in the memory among the Alsatians.

Problem: A much smaller number of people are insensitive to pain due to an inborn abnormality of the nervous system, known as "congenital insensitivity to pain". Children with this condition incur carelessly-repeated damage to their tongues, eyes, joints, skin, and muscles. Some die before adulthood, and others have a reduced life expectancy.[citation needed] Most people with congenital insensitivity to pain have one of five hereditary sensory and autonomic neuropathies (which includes familial dysautonomia and congenital insensitivity to pain with anhidrosis). These conditions feature decreased sensitivity to pain together with other neurological abnormalities, particularly of the autonomic nervous system. A very rare syndrome with isolated congenital insensitivity to pain has been linked with mutations in the SCN9A gene, which codes for a sodium channel (Nav1.7) necessary in conducting pain nerve stimuli.
What is an insensitivity to congenital pain?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
First recognized in 1900 by Max Planck, it was originally the proportionality constant between the minimal increment of energy, E, of a hypothetical electrically charged oscillator in a cavity that contained black body radiation, and the frequency, f, of its associated electromagnetic wave. In 1905 the value E, the minimal energy increment of a hypothetical oscillator, was theoretically associated by Einstein with a "quantum" or minimal element of the energy of the electromagnetic wave itself. The light quantum behaved in some respects as an electrically neutral particle, as opposed to an electromagnetic wave. It was eventually called the photon.
Who discovered an association between the value G and quantum energy?
A: unanswerable


Context and question: At the 2012 census, 59.5% of jobs in the Paris Region were in market services (12.0% in wholesale and retail trade, 9.7% in professional, scientific, and technical services, 6.5% in information and communication, 6.5% in transportation and warehousing, 5.9% in finance and insurance, 5.8% in administrative and support services, 4.6% in accommodation and food services, and 8.5% in various other market services), 26.9% in non-market services (10.4% in human health and social work activities, 9.6% in public administration and defence, and 6.9% in education), 8.2% in manufacturing and utilities (6.6% in manufacturing and 1.5% in utilities), 5.2% in construction, and 0.2% in agriculture.
What percentage of people worked in agriculture?
Answer: 0.2


Question: The most precarious of these quake-lakes was the one located in the extremely difficult terrain at Mount Tangjia in Beichuan County, Sichuan, accessible only by foot or air; an Mi-26T heavy lift helicopter belonging to the China Flying Dragon Special Aviation Company was used to bring heavy earthmoving tractors to the affected location. This operation was coupled with the work done by PLAAF Mi-17 helicopters bringing in PLA engineering corps, explosive specialists and other personnel to join 1,200 soldiers who arrived on site by foot. Five tons of fuel to operate the machinery was airlifted to the site, where a sluice was constructed to allow the safe discharge of the bottlenecked water. Downstream, more than 200,000 people were evacuated from Mianyang by June 1 in anticipation of the dam bursting.
Is there an answer to this question: How could you only get to this quake lake?

Answer: by foot or air


QUES: Starting in 1940 (18 months before Pearl Harbor), the nation mobilized, giving high priority to air power. American involvement in World War II in 1940–41 was limited to providing war material and financial support to Britain, the Soviet Union, and the Republic of China. The U.S. entered officially on 8 December 1941 following the Japanese attack on Pearl Harbor, Hawaii. Japanese forces soon seized American, Dutch, and British possessions across the Pacific and Southeast Asia, except for Australia, which became a main American forward base along with Hawaii.

What event led to America entering the war?
What is the answer?
ANS:
the Japanese attack on Pearl Harbor, Hawaii
