Problem: As another example, she points to work by Thomas et al., who sought to distinguish between the Y chromosomes of Jewish priests (Kohanim), (in Judaism, membership in the priesthood is passed on through the father's line) and the Y chromosomes of non-Jews. Abu el-Haj concluded that this new "race science" calls attention to the importance of "ancestry" (narrowly defined, as it does not include all ancestors) in some religions and in popular culture, and people's desire to use science to confirm their claims about ancestry; this "race science", she argues, is fundamentally different from older notions of race that were used to explain differences in human behaviour or social status:
How were older notions of race used?
The answer is the following: to explain differences in human behaviour or social status

Problem: Subsequently, in October 2001, U.S. forces (with UK and coalition allies) invaded Afghanistan to oust the Taliban regime. On 7 October 2001, the official invasion began with British and U.S. forces conducting airstrike campaigns over enemy targets. Kabul, the capital city of Afghanistan, fell by mid-November. The remaining al-Qaeda and Taliban remnants fell back to the rugged mountains of eastern Afghanistan, mainly Tora Bora. In December, Coalition forces (the U.S. and its allies) fought within that region. It is believed that Osama bin Laden escaped into Pakistan during the battle.
When did the US begin airstrikes on Afghanistan?
The answer is the following: 7 October 2001

Problem: In 1868, the horse-drawn tram company Compania de Tranvias al Paso del Molino y Cerro created the first lines connecting Montevideo with Union, the beach resort of Capurro and the industrialized and economically independent Villa del Cerro, at the time called Cosmopolis. In the same year, the Mercado del Puerto was inaugurated. In 1869, the first railway line of the company Ferrocarril Central del Uruguay was inaugurated connecting Bella Vista with the town of Las Piedras. During the same year and the next, the neighbourhoods Colon, Nuevo Paris and La Comercial were founded. The famous to our days Sunday market of Tristan Narvaja Street was established in Cordon in 1870. Public water supply was established in 1871. In 1878, Bulevar Circunvalacion was constructed, a boulevard starting from Punta Carretas, going up to the north end of the city and then turning west to end at the beach of Capurro. It was renamed to Artigas Boulevard (its current name) in 1885. By Decree, on 8 January 1881, the area Los Pocitos was incorporated to the Novisima Ciudad (Most New City).
What year did Compania de Tranvias al Paso del Molino y Cerro creat the first lines connecting Montevideo with Union?
The answer is the following: 1868

Problem: The Brookings Institution reported in June 2009 that U.S. consumption accounted for more than a third of the growth in global consumption between 2000 and 2007. "The US economy has been spending too much and borrowing too much for years and the rest of the world depended on the U.S. consumer as a source of global demand." With a recession in the U.S. and the increased savings rate of U.S. consumers, declines in growth elsewhere have been dramatic. For the first quarter of 2009, the annualized rate of decline in GDP was 14.4% in Germany, 15.2% in Japan, 7.4% in the UK, 18% in Latvia, 9.8% in the Euro area and 21.5% for Mexico.
For the first quarter of 2009, what was the annualized rate of decline in GDP in Mexico?
The answer is the following:
21.5%
