At the same time, British, French, and Soviet negotiators scheduled three-party talks on military matters to occur in Moscow in August 1939, aiming to define what the agreement would specify should be the reaction of the three powers to a German attack. The tripartite military talks, started in mid-August, hit a sticking point regarding the passage of Soviet troops through Poland if Germans attacked, and the parties waited as British and French officials overseas pressured Polish officials to agree to such terms. Polish officials refused to allow Soviet troops into Polish territory if Germany attacked; as Polish foreign minister Jozef Beck pointed out, they feared that once the Red Army entered their territories, it might never leave.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why did Poland deny the proposal of the Soviet Union protecting them from a German Attack?
Ah, so.. once the Red Army entered their territories, it might never leave.

On the other hand, there are several language shift processes currently taking place. In Northern Catalonia, Catalan has followed the same trend as the other minority languages of France, with most of its native speakers being 60 or older (as of 2004). Catalan is studied as a foreign language by 30% of the primary education students, and by 15% of the secondary. The cultural association La Bressola promotes a network of community-run schools engaged in Catalan language immersion programs.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How old are most of the native language speakers in northern Catalonia?
Ah, so.. 60 or older

Many mechanical aids to calculation and measurement were constructed for astronomical and navigation use. The planisphere was a star chart invented by Abu Rayhan al-Biruni in the early 11th century. The astrolabe was invented in the Hellenistic world in either the 1st or 2nd centuries BC and is often attributed to Hipparchus. A combination of the planisphere and dioptra, the astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy. An astrolabe incorporating a mechanical calendar computer and gear-wheels was invented by Abi Bakr of Isfahan, Persia in 1235. Abu Rayhan al-Biruni invented the first mechanical geared lunisolar calendar astrolabe, an early fixed-wired knowledge processing machine with a gear train and gear-wheels, circa 1000 AD.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The astrolabe was a combination of what two devices in history?
Ah, so..
the planisphere and dioptra
