The torch was lit at a park outside at AT&T Park at about 1:17 pm PDT (20:17 UTC), briefly held aloft by American and Chinese Olympic officials. The relay descended into confusion as the first runner in the elaborately planned relay disappeared into a warehouse on a waterfront pier where it stayed for a half-an-hour. There were clashes between thousands of pro-China demonstrators, many of whom said they were bused in by the Chinese Consulate and other pro-China groups, and both pro-Tibet and Darfur protesters. The non-Chinese demonstrators were reported to have been swamped and trailed by angry crowds. Around 2 pm PDT (21:00 UTC), the torch resurfaced about 3 km (1.9 mi) away from the stadium along Van Ness Avenue, a heavily trafficked thoroughfare that was not on official route plans. Television reports showed the flame flanked by motorcycles and uniformed police officers. Two torchbearers carried the flame running slowly behind a truck and surrounded by Olympic security guards. During the torch relay, two torchbearers, Andrew Michael who uses a wheelchair and is the Vice President for Sustainable Development for the Bay Area Council and Director of Partnerships For Change, and an environmental advocate, Majora Carter, managed to display Tibetan flags in protest, resulting in their ejection from the relay. The closing ceremony at Justin Herman Plaza was canceled due to the presence of large numbers of protesters at the site. The torch run ended with a final stretch through San Francisco's Marina district and was then moved by bus to San Francisco International Airport for a makeshift closing ceremony at the terminal, from which the free media was excluded. San Jose Mercury News described the "deceiving" event as "a game of Where's Waldo, played against the landscape of a lovely city." International Olympic Committee President Jacques Rogge said the San Francisco relay had "fortunately" avoided much of the disruptions that marred the legs in London and Paris, but "was, however, not the joyous party that we had wished it to be."
Where was the last part of the San Francisco torch relay carried through before getting on a bus?
****
The answer: Marina district

This period is generally taken to coincide with a major shift in population from southern Mesopotamia toward the north. Ecologically, the agricultural productivity of the Sumerian lands was being compromised as a result of rising salinity. Soil salinity in this region had been long recognized as a major problem. Poorly drained irrigated soils, in an arid climate with high levels of evaporation, led to the buildup of dissolved salts in the soil, eventually reducing agricultural yields severely. During the Akkadian and Ur III phases, there was a shift from the cultivation of wheat to the more salt-tolerant barley, but this was insufficient, and during the period from 2100 BC to 1700 BC, it is estimated that the population in this area declined by nearly three fifths. This greatly upset the balance of power within the region, weakening the areas where Sumerian was spoken, and comparatively strengthening those where Akkadian was the major language. Henceforth Sumerian would remain only a literary and liturgical language, similar to the position occupied by Latin in medieval Europe.
How much did the population of the region decline due to the decrease in crop productivity?
****
The answer: by nearly three fifths

The problem: Answer a question about this article:
Although it had equipment capable of doing serious damage, the problem for the Luftwaffe was its unclear strategy and poor intelligence. OKL had not been informed that Britain was to be considered a potential opponent until early 1938. It had no time to gather reliable intelligence on Britain's industries. Moreover, OKL could not settle on an appropriate strategy. German planners had to decide whether the Luftwaffe should deliver the weight of its attacks against a specific segment of British industry such as aircraft factories, or against a system of interrelated industries such as Britain's import and distribution network, or even in a blow aimed at breaking the morale of the British population. The Luftwaffe's strategy became increasingly aimless over the winter of 19401941. Disputes among the OKL staff revolved more around tactics than strategy. This method condemned the offensive over Britain to failure before it began.
What did the disputes between the staff cause to happen to the strategy against Britain?
****
The answer: failure before it began

Libya began to turn towards socialism. In March 1978, the government issued guidelines for housing redistribution, attempting to ensure the population that every adult Libyan owned his own home and that nobody was enslaved to paying their rent. Most families were banned from owning more than one house, while former rental properties were seized and sold to the tenants at a heavily subsidized price. In September, Gaddafi called for the People's Committees to eliminate the "bureaucracy of the public sector" and the "dictatorship of the private sector"; the People's Committees took control of several hundred companies, converting them into worker cooperatives run by elected representatives.
In September of 1978, what bureaucracy did Gaddafi speak out against?
****
The answer:
public sector
