A new delimitation of the federal territory keeps being debated in Germany, though "Some scholars note that there are significant differences among the American states and regional governments in other federations without serious calls for territorial changes ...", as political scientist Arthur B. Gunlicks remarks. He summarizes the main arguments for boundary reform in Germany: "... the German system of dual federalism requires strong Lander that have the administrative and fiscal capacity to implement legislation and pay for it from own source revenues. Too many Lander also make coordination among them and with the federation more complicated ...". But several proposals have failed so far; territorial reform remains a controversial topic in German politics and public perception.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What keeps being debated in Germany?
Ah, so.. delimitation of the federal territory

The thermionic triode, a vacuum tube invented in 1907, enabled amplified radio technology and long-distance telephony. The triode, however, was a fragile device that consumed a lot of power. Physicist Julius Edgar Lilienfeld filed a patent for a field-effect transistor (FET) in Canada in 1925, which was intended to be a solid-state replacement for the triode. Lilienfeld also filed identical patents in the United States in 1926 and 1928. However, Lilienfeld did not publish any research articles about his devices nor did his patents cite any specific examples of a working prototype. Because the production of high-quality semiconductor materials was still decades away, Lilienfeld's solid-state amplifier ideas would not have found practical use in the 1920s and 1930s, even if such a device had been built. In 1934, German inventor Oskar Heil patented a similar device.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What year did Lilienfeld file his patent?
Ah, so.. 1925

Now with NATO support in the form of air cover, the rebel militia pushed westward, defeating loyalist armies and securing control of the centre of the country. Gaining the support of Amazigh (Berber) communities of the Nafusa Mountains, who had long been persecuted as non-Arabic speakers under Gaddafi, the NTC armies surrounded Gaddafi loyalists in several key areas of western Libya. In August, the rebels seized Zliten and Tripoli, ending the last vestiges of Gaddafist power. On 25 August, the Arab League recognised the NTC to be "the legitimate representative of the Libyan state", on which basis Libya would resume its membership in the League.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): On what date did the NTC government enter the Arab League?
Ah, so..
25 August
