Output: unanswerable


QUES: In 1922, John Jacob Astor, son of the 1st Viscount Astor, bought The Times from the Northcliffe estate. The paper gained a measure of notoriety in the 1930s with its advocacy of German appeasement; then-editor Geoffrey Dawson was closely allied with those in the government who practised appeasement, most notably Neville Chamberlain.

In 1922, who bought The Times?
What is the answer?
ANS: John Jacob Astor


QUES: The earliest recorded account of a circadian process dates from the 4th century B.C.E., when Androsthenes, a ship captain serving under Alexander the Great, described diurnal leaf movements of the tamarind tree. The observation of a circadian or diurnal process in humans is mentioned in Chinese medical texts dated to around the 13th century, including the Noon and Midnight Manual and the Mnemonic Rhyme to Aid in the Selection of Acu-points According to the Diurnal Cycle, the Day of the Month and the Season of the Year.
What did Alexander the great described?

ANS: unanswerable


Following Syria's secession, Nasser grew concerned with Amer's inability to train and modernize the army, and with the state within a state Amer had created in the military command and intelligence apparatus. In late 1961, Nasser established the Presidential Council and decreed it the authority to approve all senior military appointments, instead of leaving this responsibility solely to Amer. Moreover, he instructed that the primary criterion for promotion should be merit and not personal loyalties. Nasser retracted the initiative after Amer's allies in the officers corps threatened to mobilize against him.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why did Nasser abandon the Presidential Council?
Ah, so.. Amer's allies in the officers corps threatened to mobilize against him


Question: While hardware may be a source of insecurity, such as with microchip vulnerabilities maliciously introduced during the manufacturing process, hardware-based or assisted computer security also offers an alternative to software-only computer security. Using devices and methods such as dongles, trusted platform modules, intrusion-aware cases, drive locks, disabling USB ports, and mobile-enabled access may be considered more secure due to the physical access (or sophisticated backdoor access) required in order to be compromised. Each of these is covered in more detail below.
Try to answer this question if possible: What can hardware be a source of?
Answer: insecurity


Problem: 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.
Why were field-effect transistors not practical without high quality semiconductor materials?
