Problem: Ibn Sina wrote at least one treatise on alchemy, but several others have been falsely attributed to him. His Logic, Metaphysics, Physics, and De Caelo, are treatises giving a synoptic view of Aristotelian doctrine, though Metaphysics demonstrates a significant departure from the brand of Neoplatonism known as Aristotelianism in Ibn Sina's world; Arabic philosophers[who?][year needed] have hinted at the idea that Ibn Sina was attempting to "re-Aristotelianise" Muslim philosophy in its entirety, unlike his predecessors, who accepted the conflation of Platonic, Aristotelian, Neo- and Middle-Platonic works transmitted into the Muslim world.

Problem: In addition to the dead and wounded, government leaders feared mass psychological trauma from aerial attack and a resulting collapse of civil society. A committee of psychiatrists reported to the government in 1938 that there would be three times as many mental as physical casualties from aerial bombing, implying three to four million psychiatric patients. Winston Churchill told Parliament in 1934, "We must expect that, under the pressure of continuous attack upon London, at least three or four million people would be driven out into the open country around the metropolis." Panicked reactions during the Munich crisis, such as the migration by 150,000 to Wales, contributed to fear of societal chaos.
Who told Parliament that after long periods of attacks people would leave the cities for the country?
The answer is the following: Winston Churchill

Problem: The city of Nanjing was razed after the Sui dynasty took over it. It renamed Shengzhou () in Tang dynasty and resuscitated during the late Tang.

It renamed Jiangning () in Northern Song dynasty and renamed Jiankang in Southern Song dynasty. Jiankang's textile industry burgeoned and thrived during the Song dynasty despite the constant threat of foreign invasions from the north by the Jurchen-led Jin dynasty.
