Problem: Czech language:

Czech typographical features not associated with phonetics generally resemble those of most Latin European languages, including English. Proper nouns, honorifics, and the first letters of quotations are capitalized, and punctuation is typical of other Latin European languages. Writing of ordinal numerals is similar to most European languages. The Czech language uses a decimal comma instead of a decimal point. When writing a long number, spaces between every three numbers (e.g. between hundreds and thousands) may be used for better orientation in handwritten texts, but not in decimal places, like in English. The number 1,234,567.8910 may be written as 1234567,8910 or 1 234 567,8910. Ordinal numbers (1st) use a point as in German (1.). In proper noun phrases (except personal names), only the first word is capitalized (Prazsky hrad, Prague Castle).

Problem: Alsace:

"Alsatia", the Latin form of Alsace's name, has long ago entered the English language with the specialized meaning of "a lawless place" or "a place under no jurisdiction" - since Alsace was conceived by English people to be such. It was used into the 20th century as a term for a ramshackle marketplace, "protected by ancient custom and the independence of their patrons". As of 2007, the word is still in use among the English and Australian judiciaries with the meaning of a place where the law cannot reach: "In setting up the Serious Organised Crime Agency, the state has set out to create an Alsatia - a region of executive action free of judicial oversight," Lord Justice Sedley in UMBS v SOCA 2007.

When did the use of the word Alsatia fall out of practice?

A: unanswerable

Problem: Napoleon:

Napoleon turned his focus to domestic affairs after the war. Empress Josephine had still not given birth to a child from Napoleon, who became worried about the future of his empire following his death. Desperate for a legitimate heir, Napoleon divorced Josephine in January 1810 and started looking for a new wife. Hoping to cement the recent alliance with Austria through a family connection, Napoleon married the Archduchess Marie Louise, who was 18 years old at the time. On 20 March 1811, Marie Louise gave birth to a baby boy, whom Napoleon made heir apparent and bestowed the title of King of Rome. His son never actually ruled the empire, but historians still refer to him as Napoleon II.

How old was Archduchess Marie Louise when she married Napoleon?

A: 18

Problem: Alexander Graham Bell:

The AEA's work progressed to heavier-than-air machines, applying their knowledge of kites to gliders. Moving to Hammondsport, the group then designed and built the Red Wing, framed in bamboo and covered in red silk and powered by a small air-cooled engine. On March 12, 1908, over Keuka Lake, the biplane lifted off on the first public flight in North America.[N 24] [N 25] The innovations that were incorporated into this design included a cockpit enclosure and tail rudder (later variations on the original design would add ailerons as a means of control). One of the AEA's inventions, a practical wingtip form of the aileron, was to become a standard component on all aircraft. [N 26] The White Wing and June Bug were to follow and by the end of 1908, over 150 flights without mishap had been accomplished. However, the AEA had depleted its initial reserves and only a $15,000 grant from Mrs. Bell allowed it to continue with experiments. Lt. Selfridge had also become the first person killed in a powered heavier-than-air flight in a crash of the Wright Flyer at Fort Myer, Virginia, on September 17, 1908.

Who was the first person to die in a plane crash?

A:
Selfridge
