Question: To the north, the Sahara skirts the Mediterranean Sea in Egypt and portions of Libya, but in Cyrenaica and the Maghreb, the Sahara borders the Mediterranean forest, woodland, and scrub ecoregions of northern Africa, all of which have a Mediterranean climate characterized by hot summers and cool and rainy winters. According to the botanical criteria of Frank White and geographer Robert Capot-Rey, the northern limit of the Sahara corresponds to the northern limit of date palm cultivation and the southern limit of the range of esparto, a grass typical of the Mediterranean climate portion of the Maghreb and Iberia. The northern limit also corresponds to the 100 mm (3.9 in) isohyet of annual precipitation.

Answer: unanswerable
Question: The infrared portion of the spectrum has several useful benefits for astronomers. Cold, dark molecular clouds of gas and dust in our galaxy will glow with radiated heat as they are irradiated by imbedded stars. Infrared can also be used to detect protostars before they begin to emit visible light. Stars emit a smaller portion of their energy in the infrared spectrum, so nearby cool objects such as planets can be more readily detected. (In the visible light spectrum, the glare from the star will drown out the reflected light from a planet.)

Question: Following his triumph, Napoleon imposed the first elements of the Continental System through the Berlin Decree issued in November 1806. The Continental System, which prohibited European nations from trading with Britain, was widely violated throughout his reign. In the next few months, Napoleon marched against the advancing Russian armies through Poland and was involved in the bloody stalemate at the Battle of Eylau in February 1807. After a period of rest and consolidation on both sides, the war restarted in June with an initial struggle at Heilsberg that proved indecisive. On 14 June, however, Napoleon finally obtained an overwhelming victory over the Russians at the Battle of Friedland, wiping out the majority of the Russian army in a very bloody struggle. The scale of their defeat convinced the Russians to make peace with the French. On 19 June, Czar Alexander sent an envoy to seek an armistice with Napoleon. The latter assured the envoy that the Vistula River represented the natural borders between French and Russian influence in Europe. On that basis, the two emperors began peace negotiations at the town of Tilsit after meeting on an iconic raft on the River Niemen. The very first thing Alexander said to Napoleon was probably well-calibrated: "I hate the English as much as you do."

Answer: November 1806
Question: Modern Nationalism, as developed especially since the French Revolution, has made the distinction between "language" and "dialect" an issue of great political importance. A group speaking a separate "language" is often seen as having a greater claim to being a separate "people", and thus to be more deserving of its own independent state, while a group speaking a "dialect" tends to be seen not as "a people" in its own right, but as a sub-group, part of a bigger people, which must content itself with regional autonomy.[citation needed] The distinction between language and dialect is thus inevitably made at least as much on a political basis as on a linguistic one, and can lead to great political controversy, or even armed conflict.
