QUES: The most catastrophic earthquakes we know of occurred in 31 BCE, 363, 749, and 1033 CE, that is every ca. 400 years on average. Destructive earthquakes leading to serious loss of life strike about every 80 years. While stringent construction regulations are currently in place and recently built structures are earthquake-safe, as of 2007[update] the majority of the buildings in Israel were older than these regulations and many public buildings as well as 50,000 residential buildings did not meet the new standards and were "expected to collapse" if exposed to a strong quake. Given the fragile political situation of the Middle East region and the presence there of major holy sites, a quake reaching magnitude 7 on the Richter scale could have dire consequences for world peace.

QUES: Much of the study in the madrasah college centred on examining whether certain opinions of law were orthodox. This scholarly process of "determining orthodoxy began with a question which the Muslim layman, called in that capacity mustaftī, presented to a jurisconsult, called mufti, soliciting from him a response, called fatwa, a legal opinion (the religious law of Islam covers civil as well as religious matters). The mufti (professor of legal opinions) took this question, studied it, researched it intensively in the sacred scriptures, in order to find a solution to it. This process of scholarly research was called ijtihād, literally, the exertion of one's efforts to the utmost limit."

QUES: The First Opium War revealed the outdated state of the Chinese military. The Qing navy, composed entirely of wooden sailing junks, was severely outclassed by the modern tactics and firepower of the British Royal Navy. British soldiers, using advanced muskets and artillery, easily outmaneuvered and outgunned Qing forces in ground battles. The Qing surrender in 1842 marked a decisive, humiliating blow to China. The Treaty of Nanjing, the first of the unequal treaties, demanded war reparations, forced China to open up the five ports of Canton, Amoy, Fuchow, Ningpo and Shanghai to western trade and missionaries, and to cede Hong Kong Island to Britain. It revealed many inadequacies in the Qing government and provoked widespread rebellions against the already hugely unpopular regime.
