Problem: Napoleon:

Before going to Iberia, Napoleon decided to address several lingering issues with the Russians. At the Congress of Erfurt in October 1808, Napoleon hoped to keep Russia on his side during the upcoming struggle in Spain and during any potential conflict against Austria. The two sides reached an agreement, the Erfurt Convention, that called upon Britain to cease its war against France, that recognized the Russian conquest of Finland from Sweden, and that affirmed Russian support for France in a possible war against Austria "to the best of its ability." Napoleon then returned to France and prepared for war. The Grande Armee, under the Emperor's personal command, rapidly crossed the Ebro River in November 1808 and inflicted a series of crushing defeats against the Spanish forces. After clearing the last Spanish force guarding the capital at Somosierra, Napoleon entered Madrid on 4 December with 80,000 troops. He then unleashed his soldiers against Moore and the British forces. The British were swiftly driven to the coast, and they withdrew from Spain entirely after a last stand at the Battle of Corunna in January 1809.

In what year was the Congress of Erfurt held?

A: 1808

Problem: Jews are often identified as belonging to one of two major groups: the Ashkenazim and the Sephardim. Ashkenazim, or "Germanics" (Ashkenaz meaning "Germany" in Hebrew), are so named denoting their German Jewish cultural and geographical origins, while Sephardim, or "Hispanics" (Sefarad meaning "Spain/Hispania" or "Iberia" in Hebrew), are so named denoting their Spanish/Portuguese Jewish cultural and geographic origins. The more common term in Israel for many of those broadly called Sephardim, is Mizrahim (lit. "Easterners", Mizrach being "East" in Hebrew), that is, in reference to the diverse collection of Middle Eastern and North African Jews who are often, as a group, referred to collectively as Sephardim (together with Sephardim proper) for liturgical reasons, although Mizrahi Jewish groups and Sephardi Jews proper are ethnically distinct.
How many major groups do the Ashkenazim belong to?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Sumerian religion seems to have been founded upon two separate cosmogenic myths. The first saw creation as the result of a series of hieros gami or sacred marriages, involving the reconciliation of opposites, postulated as a coming together of male and female divine beings; the gods. This continued to influence the whole Mesopotamian mythos. Thus in the Enuma Elish the creation was seen as the union of fresh and salt water; as male Abzu, and female Tiamat. The product of that union, Lahm and Lahmu, "the muddy ones", were titles given to the gate keepers of the E-Abzu temple of Enki, in Eridu, the first Sumerian city. Describing the way that muddy islands emerge from the confluence of fresh and salty water at the mouth of the Euphrates, where the river deposited its load of silt, a second hieros gamos supposedly created Anshar and Kishar, the "sky-pivot" or axle, and the "earth pivot", parents in turn of Anu (the sky) and Ki (the earth). Another important Sumerian hieros gamos was that between Ki, here known as Ninhursag or "Lady Sacred Mountain", and Enki of Eridu, the god of fresh water which brought forth greenery and pasture.
What were the titles given to the gate keeps of the E-Abzu temple of Enki?
A: the muddy ones

Question: Additionally, henna is an important part of Somali culture. It is worn by Somali women on their hands, arms, feet and neck during weddings, Eid, Ramadan, and other festive occasions. Somali henna designs are similar to those in the Arabian peninsula, often featuring flower motifs and triangular shapes. The palm is also frequently decorated with a dot of henna and the fingertips are dipped in the dye. Henna parties are usually held before the wedding takes place. Somali women have likewise traditionally applied kohl (kuul) to their eyes. Usage of the eye cosmetic in the Horn region is believed to date to the ancient Land of Punt.
Is there an answer to this question: From what ancient region did kuul application come?

Answer: Land of Punt

Question: Nevertheless, it was radar that proved to be critical weapon in the night battles over Britain from this point onward. Dowding had introduced the concept of airborne radar and encouraged its usage. Eventually it would become a success. On the night of 22/23 July 1940, Flying Officer Cyril Ashfield (pilot), Pilot Officer Geoffrey Morris (Observer) and Flight Sergeant Reginald Leyland (Air Intercept radar operator) of the Fighter Interception Unit became the first pilot and crew to intercept and destroy an enemy aircraft using onboard radar to guide them to a visual interception, when their AI night fighter brought down a Do 17 off Sussex. On 19 November 1940 the famous RAF night fighter ace John Cunningham shot down a Ju 88 bomber using airborne radar, just as Dowding had predicted.
Is there an answer to this question: What was critical in the night battles over Britain?

Answer:
radar
