Problem: Oklahoma:

Oklahoma is between the Great Plains and the Ozark Plateau in the Gulf of Mexico watershed, generally sloping from the high plains of its western boundary to the low wetlands of its southeastern boundary. Its highest and lowest points follow this trend, with its highest peak, Black Mesa, at 4,973 feet (1,516 m) above sea level, situated near its far northwest corner in the Oklahoma Panhandle. The state's lowest point is on the Little River near its far southeastern boundary near the town of Idabel, OK, which dips to 289 feet (88 m) above sea level.

What plateau is Oklahoma near?

A: Ozark Plateau

Problem: Human Development Index:

The origins of the HDI are found in the annual Development Reports of the United Nations Development Programme (UNDP). These were devised and launched by Pakistani economist Mahbub ul Haq in 1990 and had the explicit purpose "to shift the focus of development economics from national income accounting to people-centered policies". To produce the Human Development Reports, Mahbub ul Haq formed a group of development economists including Paul Streeten, Frances Stewart, Gustav Ranis, Keith Griffin, Sudhir Anand, and Meghnad Desai. Working alongside Nobel laureate Amartya Sen, they worked on capabilities and functions that provided the underlying conceptual framework. Haq was sure that a simple composite measure of human development was needed in order to convince the public, academics, and politicians that they can and should evaluate development not only by economic advances but also improvements in human well-being. Sen initially opposed this idea, but he soon went on to help Haq develop the Index. Sen was worried that it was going to be difficult to capture the full complexity of human capabilities in a single index, but Haq persuaded him that only a single number would shift the immediate attention of politicians from economic to human well-being.

Mahbub ul Haq was hoping to shift the focus of development economics to what type of policies?
---
A: people-centered policies

Problem: Middle Ages:

The importance of infantry and light cavalry began to decline during the early Carolingian period, with a growing dominance of elite heavy cavalry. The use of militia-type levies of the free population declined over the Carolingian period. Although much of the Carolingian armies were mounted, a large proportion during the early period appear to have been mounted infantry, rather than true cavalry. One exception was Anglo-Saxon England, where the armies were still composed of regional levies, known as the fyrd, which were led by the local elites. In military technology, one of the main changes was the return of the crossbow, which had been known in Roman times and reappeared as a military weapon during the last part of the Early Middle Ages. Another change was the introduction of the stirrup, which increased the effectiveness of cavalry as shock troops. A technological advance that had implications beyond the military was the horseshoe, which allowed horses to be used in rocky terrain.

What Roman weapon began to be used again in the Early Middle Ages?
---
A: the crossbow

Problem: Muammar Gaddafi:

Following his ascension to power, Gaddafi moved into the Bab al-Azizia barracks, a six-mile long fortified compound located two miles from the center of Tripoli. His home and office at Azizia was a bunker designed by West German engineers, while the rest of his family lived in a large two-story building. Within the compound were also two tennis courts, a soccer field, several gardens, camels, and a Bedouin tent in which he entertained guests. In the 1980s, his lifestyle was considered modest in comparison to those of many other Arab leaders. Gaddafi allegedly worked for years with Swiss banks to launder international banking transactions. In November 2011, The Sunday Times identified property worth 1 billion in the UK that Gaddafi allegedly owned. Gaddafi had an Airbus A340 private jet, which he bought from Prince Al-Waleed bin Talal of Saudi Arabia for $120 million in 2003. Operated by Tripoli-based Afriqiyah Airways and decorated externally in their colours, it had various luxuries including a jacuzzi.

What was the value of Gaddafi's supposed British property holdings as of November 2011?

A:
1 billion
