Problem: Seven Years%27 War:

For much of the eighteenth century, France approached its wars in the same way. It would let colonies defend themselves or would offer only minimal help (sending them limited numbers of troops or inexperienced soldiers), anticipating that fights for the colonies would most likely be lost anyway. This strategy was to a degree forced upon France: geography, coupled with the superiority of the British navy, made it difficult for the French navy to provide significant supplies and support to French colonies. Similarly, several long land borders made an effective domestic army imperative for any French ruler. Given these military necessities, the French government, unsurprisingly, based its strategy overwhelmingly on the army in Europe: it would keep most of its army on the continent, hoping for victories closer to home. The plan was to fight to the end of hostilities and then, in treaty negotiations, to trade territorial acquisitions in Europe to regain lost overseas possessions. This approach did not serve France well in the war, as the colonies were indeed lost, but although much of the European war went well, by its end France had few counterbalancing European successes.

Why did the French rulers need a large domestic army?

A: several long land borders made an effective domestic army imperative

Problem: The loss of eight battleships and 2,403 Americans at Pearl Harbor forced the U.S. to rely on its remaining aircraft carriers, which won a major victory over Japan at Midway just six months into the war, and on its growing submarine fleet. The Navy and Marine Corps followed this up with an island hopping campaign across the central and south Pacific in 194345, reaching the outskirts of Japan in the Battle of Okinawa. During 1942 and 1943, the U.S. deployed millions of men and thousands of planes and tanks to the UK, beginning with the strategic bombing of Nazi Germany and occupied Europe and leading up to the Allied invasions of occupied North Africa in November 1942, Sicily and Italy in 1943, France in 1944, and the invasion of Germany in 1945, parallel with the Soviet invasion from the east. That led to the surrender of Nazi Germany in May 1945. In the Pacific, the U.S. experienced much success in naval campaigns during 1944, but bloody battles at Iwo Jima and Okinawa in 1945 led the U.S. to look for a way to end the war with minimal loss of American lives. The U.S. used atomic bombs on Hiroshima and Nagasaki to destroy the Japanese war effort and to shock the Japanese leadership, which quickly caused the surrender of Japan.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Sun has been openly antagonistic towards other European nations, particularly the French and Germans. During the 1980s and 1990s, the nationalities were routinely described in copy and headlines as "frogs", "krauts" or "hun". As the paper is opposed to the EU it has referred to foreign leaders who it deemed hostile to the UK in unflattering terms. Former President Jacques Chirac of France, for instance, was branded "le Worm". An unflattering picture of German chancellor Angela Merkel, taken from the rear, bore the headline "I'm Big in the Bumdestag" (17 April 2006).
How was French president Jacques Chirac described by The Sun?
A: le Worm

Context and question: A nonstandard dialect, like a standard dialect, has a complete vocabulary, grammar, and syntax, but is usually not the beneficiary of institutional support. Examples of a nonstandard English dialect are Southern American English, Western Australian English, Scouse and Tyke. The Dialect Test was designed by Joseph Wright to compare different English dialects with each other.
Unlike a standard dialect, what does a nonstandard dialect have?
Answer: unanswerable

Question: The BBC also introduced Ceefax, the first teletext service, starting in 1974. This service allows BBC viewers to view textual information such as the latest news on their television. CEEFAX has not made a full transition to digital television, instead being replaced by the new interactive BBCi service.
Is there an answer to this question: When did Ceefax make the full transition to digital television?

Answer: unanswerable

QUES: In 1671, Robert Boyle discovered and described the reaction between iron filings and dilute acids, which results in the production of hydrogen gas. In 1766, Henry Cavendish was the first to recognize hydrogen gas as a discrete substance, by naming the gas from a metal-acid reaction "flammable air". He speculated that "flammable air" was in fact identical to the hypothetical substance called "phlogiston" and further finding in 1781 that the gas produces water when burned. He is usually given credit for its discovery as an element. In 1783, Antoine Lavoisier gave the element the name hydrogen (from the Greek - hydro meaning "water" and - genes meaning "creator") when he and Laplace reproduced Cavendish's finding that water is produced when hydrogen is burned.

Who recognized hydrogen gas as a discreet substance?
