Problem: Umayyad Caliphate:

Yazid died while the siege was still in progress, and the Umayyad army returned to Damascus, leaving Ibn al-Zubayr in control of Mecca. Yazid's son Muawiya II (68384) initially succeeded him but seems to have never been recognized as caliph outside of Syria. Two factions developed within Syria: the Confederation of Qays, who supported Ibn al-Zubayr, and the Quda'a, who supported Marwan, a descendant of Umayya via Wa'il ibn Umayyah. The partisans of Marwan triumphed at a battle at Marj Rahit, near Damascus, in 684, and Marwan became caliph shortly thereafter.

Who was the son of Yazid?
---
A: Muawiya II

Problem: History of science:

The above "history of economics" reflects modern economic textbooks and this means that the last stage of a science is represented as the culmination of its history (Kuhn, 1962). The "invisible hand" mentioned in a lost page in the middle of a chapter in the middle of the to "Wealth of Nations", 1776, advances as Smith's central message.[clarification needed] It is played down that this "invisible hand" acts only "frequently" and that it is "no part of his [the individual's] intentions" because competition leads to lower prices by imitating "his" invention. That this "invisible hand" prefers "the support of domestic to foreign industry" is cleansedoften without indication that part of the citation is truncated. The opening passage of the "Wealth" containing Smith's message is never mentioned as it cannot be integrated into modern theory: "Wealth" depends on the division of labour which changes with market volume and on the proportion of productive to Unproductive labor.

When was Wealth of Nations written?

A: 1776

Problem: Edmund Burke:

Burke believed that property was essential to human life. Because of his conviction that people desire to be ruled and controlled, the division of property formed the basis for social structure, helping develop control within a property-based hierarchy. He viewed the social changes brought on by property as the natural order of events, which should be taking place as the human race progressed. With the division of property and the class system, he also believed that it kept the monarch in check to the needs of the classes beneath the monarch. Since property largely aligned or defined divisions of social class, class too, was seen as naturalpart of a social agreement that the setting of persons into different classes, is the mutual benefit of all subjects. Concern for property is not Burke's only influence. As Christopher Hitchens summarises, "If modern conservatism can be held to derive from Burke, it is not just because he appealed to property owners in behalf of stability but also because he appealed to an everyday interest in the preservation of the ancestral and the immemorial."

What did Christopher Hitchens believe was essential to human life?

Problem: Neptune:

Neptune's mass of 1.02431026 kg, is intermediate between Earth and the larger gas giants: it is 17 times that of Earth but just 1/19th that of Jupiter.[d] Its gravity at 1 bar is 11.15 m/s2, 1.14 times the surface gravity of Earth, and surpassed only by Jupiter. Neptune's equatorial radius of 24,764 km is nearly four times that of Earth. Neptune, like Uranus, is an ice giant, a subclass of giant planet, due to their smaller size and higher concentrations of volatiles relative to Jupiter and Saturn. In the search for extrasolar planets, Neptune has been used as a metonym: discovered bodies of similar mass are often referred to as "Neptunes", just as scientists refer to various extrasolar bodies as "Jupiters".

What is the equatoral radius of Earth?

A:
unanswerable
