Problem: Paris:

The first book printed in France, Epistolae ("Letters"), by Gasparinus de Bergamo (Gasparino da Barzizza), was published in Paris in 1470 by the press established by Johann Heynlin. Since then, Paris has been the centre of the French publishing industry, the home of some of the world's best-known writers and poets, and the setting for many classic works of French literature. Almost all the books published in Paris in the Middle Ages were in Latin, rather than French. Paris did not become the acknowledged capital of French literature until the 17th century, with authors such as Boileau, Corneille, La Fontaine, Molière, Racine, several coming from the provinces, and the foundation of the Académie française. In the 18th century, the literary life of Paris revolved around the cafés and salons, and was dominated by Voltaire, Jean-Jacques Rousseau, Pierre de Marivaux, and Beaumarchais.

Problem: 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.
At the start of the conflict with the Allies, what did Japan do?
---
Answer: seized American, Dutch, and British possessions across the Pacific and Southeast Asia

In 1996, a surrogate character mechanism was implemented in Unicode 2.0, so that Unicode was no longer restricted to 16 bits. This increased the Unicode codespace to over a million code points, which allowed for the encoding of many historic scripts (e.g., Egyptian Hieroglyphs) and thousands of rarely used or obsolete characters that had not been anticipated as needing encoding. Among the characters not originally intended for Unicode are rarely used Kanji or Chinese characters, many of which are part of personal and place names, making them rarely used, but much more essential than envisioned in the original architecture of Unicode.
What types of characters were removed with Unicode 2.0?
A: unanswerable


Context and question: Immigration to the United States of Spanish-speaking Cubans began because of Cuba's political instability upon achieving independence. The deposition of Fulgencio Batista's dictatorship and the ascension of Fidel Castro's government in 1959 increased Cuban immigration to the United States, hence there are some one million Cubans in the United States, most settled in southern and central Florida, while other Cubans live in the Northeastern United States; most are fluent in Spanish. In the city of Miami today Spanish is the first language mostly due to Cuban immigration.
Where do most Spanish live?
Answer: unanswerable


Question: Ethernet standards require electrical isolation between the networked device (computer, phone, etc.) and the network cable up to 1500 V AC or 2250 V DC for 60 seconds. USB has no such requirement as it was designed for peripherals closely associated with a host computer, and in fact it connects the peripheral and host grounds. This gives Ethernet a significant safety advantage over USB with peripherals such as cable and DSL modems connected to external wiring that can assume hazardous voltages under certain fault conditions.
Is there an answer to this question: USB connects what?

Answer: the peripheral and host grounds

When the Xbox 360 was released, Microsoft's online gaming service Xbox Live was shut down for 24 hours and underwent a major upgrade, adding a basic non-subscription service called Xbox Live Silver (later renamed Xbox Live Free) to its already established premium subscription-based service (which was renamed Gold). Xbox Live Free is included with all SKUs of the console. It allows users to create a user profile, join on message boards, and access Microsoft's Xbox Live Arcade and Marketplace and talk to other members. A Live Free account does not generally support multiplayer gaming; however, some games that have rather limited online functions already, (such as Viva Piñata) or games that feature their own subscription service (e.g. EA Sports games) can be played with a Free account. Xbox Live also supports voice the latter a feature possible with the Xbox Live Vision.
How long was voice support down after its launch?
A:
unanswerable
