On Thursday, September 19, 1985, at 7:19 am local time, Mexico City was struck by an earthquake of magnitude 8.1 on the Richter scale. Although this earthquake was not as deadly or destructive as many similar events in Asia and other parts of Latin America, it proved to be a disaster politically for the one-party government. The government was paralyzed by its own bureaucracy and corruption, forcing ordinary citizens to create and direct their own rescue efforts and to reconstruct much of the housing that was lost as well.
What day of the week did the major earthquake strike Mexico City?
A: Thursday

The Gurjar Pratihar Empire acted as a barrier for Arab invaders from the 8th to the 11th century. The chief accomplishment of the Gurjara Pratihara empire lies in its successful resistance to foreign invasions from the west, starting in the days of Junaid. Historian R. C. Majumdar says that this was openly acknowledged by the Arab writers. He further notes that historians of India have wondered at the slow progress of Muslim invaders in India, as compared with their rapid advance in other parts of the world. Now there seems little doubt that it was the power of the Gurjara Pratihara army that effectively barred the progress of the Arabs beyond the confines of Sindh, their first conquest for nearly 300 years.
Arab conquest was limited to what region?
A: Sindh

Although Egypt was a majority Christian country before the 7th Century, after Islam arrived, the country was slowly Islamified to become a majority Muslim country. Egypt emerged as a centre of politics and culture in the Muslim world. Under Anwar Sadat, Islam became the official state religion and Sharia the main source of law. It is estimated that 15 million Egyptians follow Native Sufi orders, with the Sufi leadership asserting that the numbers are much greater as many Egyptian Sufis are not officially registered with a Sufi order.
Under what leader did Islam become official religion of Egypt?
A: Anwar Sadat

Vaisesika metaphysical premises are founded on a form of atomism, that the reality is composed of four substances (earth, water, air, fire). Each of these four are of two types: atomic (paramanu) and composite. An atom is, according to Vaisesika scholars, that which is indestructible (anitya), indivisible, and has a special kind of dimension, called "small" (anu). A composite, in this philosophy, is defined to be anything which is divisible into atoms. Whatever human beings perceive is composite, while atoms are invisible. The Vaisesikas stated that size, form, truths and everything that human beings experience as a whole is a function of atoms, their number and their spatial arrangements, their guna (quality), karma (activity), samanya (commonness), visesa (particularity) and amavaya (inherence, inseparable connectedness of everything).
How many realities are there?
A:
unanswerable
