Problem: In 1970, seagoing pilots became retrospectively insurable, and gained full social security as members of the Non-Manual Workers Insurance Institute. That same year, a special regulation came into force for District Master Chimney Sweeps, making them fully insurable under the Craftsmans Insurance Scheme. An increase was made in tax-free allowances for children, which enabled 1,000,000 families to claim an allowance for the second child, compared to 300,000 families previously. The Second Modification and Supplementation Law (1970) increased the allowance for the third child from DM 50 to DM 60, raised the income-limit for the second child allowance from DM 7,800 to DM 13,200; subsequently increased to DM 15,000 by the third modification law (December 1971), DM 16,800 by the fourth modification law (November 1973), and to DM 18,360 by the fifth modification law (December 1973). A flexible retirement age after 62 years was introduced (1972) for invalids and handicapped persons, and social assistance was extended to those who previously had to be helped by their relatives. From 1971, special subventions were provided to enable young farmers to quit farming "and facilitate their entry into the non-agricultural pension system by means of back payments."

Which month in 1973 had a lowest DM modification law, November or December?
Answer: November

Problem: Trying to snap a three-game losing streak, the 49ers went home for a Week 9 interconference duel with the Tennessee Titans. In the first quarter, San Francisco struck first as kicker Joe Nedney made a 40-yard field goal. The Titans would respond with a 21-yard field goal from kicker Rob Bironas. Tennessee would take the lead in the second quarter as quarterback Vince Young got a 7-yard touchdown run, yet the 49ers regained the lead with running back Frank Gore's 3-yard touchdown run and quarterback Alex Smith's 12-yard touchdown pass to wide receiver Jason Hill. The Titans would tie the game in the third quarter with a 1-yard touchdown run from running back Chris Johnson. San Francisco would begin the fourth quarter with Nedney booting a 25-yard field goal, but Tennessee would take the lead with Johnson's 2-yard touchdown run, kicker Rob Bironas' 28-yard field goal, and cornerback Cortland Finnegan returning an interception 39yards for a touchdown. The Niners tried to rally as Smith hooked up with Hill again on a 3-yard touchdown pass, but the Titans' defense would prevent further progress.

How many yards were scored on rushing touchdowns in the first two quarters?
Answer: 10

Problem: In Europe, before the outbreak of the war, the Allies had significant advantages in both population and economics. In 1938, the Western Allies had a 30 per cent larger population and a 30 per cent higher gross domestic product than the European Axis powers ; if colonies are included, it then gives the Allies more than a 5:1 advantage in population and nearly 2:1 advantage in GDP. In Asia at the same time, China had roughly six times the population of Japan, but only an 89 per cent higher GDP; this is reduced to three times the population and only a 38 per cent higher GDP if Japanese colonies are included. The United States provided about two-thirds of all the ordnance used by the Allies in terms of warships, transports, warplanes, artillery, tanks, trucks, and ammunition. Though the Allies' economic and population advantages were largely mitigated during the initial rapid blitzkrieg attacks of Germany and Japan, they became the decisive factor by 1942, after the United States and Soviet Union joined the Allies, as the war largely settled into one of attrition. While the Allies' ability to out-produce the Axis is often attributed to the Allies having more access to natural resources, other factors, such as Germany and Japan's reluctance to employ women in the labour force, Allied strategic bombing, and Germany's late shift to a war economy contributed significantly. Additionally, neither Germany nor Japan planned to fight a protracted war, and were not equipped to do so. To improve their production, Germany and Japan used millions of slave labourers; Germany used about 12 million people, mostly from Eastern Europe, while Japan used more than 18 million people in Far East Asia.

How many million more slaves did Japan use than Germany in the war?
Answer: 6

Problem: Elam was a pre-Iranic ancient civilization located to the east of Mesopotamia. In the Old Elamite period , Elam consisted of kingdoms on the Iranian Plateau, centered in Anshan, and from the mid-2nd millennium BC, it was centered in Susa in the Khuzestan lowlands. Its culture played a crucial role in the Gutian Empire and especially during the Iranic Achaemenid dynasty that succeeded it. The Oxus civilization was a Bronze Age Central Asian culture dated to c.2300-1700 BC and centered on the upper Amu Darya . In the Early Bronze Age the culture of the Kopet Dag oases and Altyndepe developed a proto-urban society. This corresponds to level IV at Namazga-Tepe. Altyndepe was a major centre even then. Pottery was wheel-turned. Grapes were grown. The height of this urban development was reached in the Middle Bronze Age c.2300 BC, corresponding to level V at Namazga-Depe. This Bronze Age culture is called the Bactria-Margiana Archaeological Complex . The Kulli culture, similar to those of the Indus Valley Civilisation, was located in southern Balochistan c.2500-2000 BC. Agriculture was the economical base of this people. At several places dams were found, providing evidence for a highly developed water management system.

How many years was the Kulli civilization located in southern Balochistan?
