There has been much debate over categorizing the situation in Darfur as genocide. The ongoing conflict in Darfur, Sudan, which started in 2003, was declared a "genocide" by United States Secretary of State Colin Powell on 9 September 2004 in testimony before the Senate Foreign Relations Committee. Since that time however, no other permanent member of the UN Security Council followed suit. In fact, in January 2005, an International Commission of Inquiry on Darfur, authorized by UN Security Council Resolution 1564 of 2004, issued a report to the Secretary-General stating that "the Government of the Sudan has not pursued a policy of genocide." Nevertheless, the Commission cautioned that "The conclusion that no genocidal policy has been pursued and implemented in Darfur by the Government authorities, directly or through the militias under their control, should not be taken in any way as detracting from the gravity of the crimes perpetrated in that region. International offences such as the crimes against humanity and war crimes that have been committed in Darfur may be no less serious and heinous than genocide."
In front of which committee did Powell testify?
A: the Senate Foreign Relations Committee

Darwin proposes sexual selection, driven by competition between males for mates, to explain sexually dimorphic features such as lion manes, deer antlers, peacock tails, bird songs, and the bright plumage of some male birds. He analysed sexual selection more fully in The Descent of Man, and Selection in Relation to Sex (1871). Natural selection was expected to work very slowly in forming new species, but given the effectiveness of artificial selection, he could "see no limit to the amount of change, to the beauty and infinite complexity of the coadaptations between all organic beings, one with another and with their physical conditions of life, which may be effected in the long course of time by nature's power of selection". Using a tree diagram and calculations, he indicates the "divergence of character" from original species into new species and genera. He describes branches falling off as extinction occurred, while new branches formed in "the great Tree of life ... with its ever branching and beautiful ramifications".
What did Darwin use to illustrate the way that original species change and adapt into new ones?
A: a tree diagram and calculations

The wastewater treatment plant and distribution system of water mains, pumping stations and storage facilities provide water to approximately 62,000 customers in the city. There is also a wastewater treatment plant located on the south bank of the James River. This plant can treat up to 70 million gallons of water per day of sanitary sewage and stormwater before returning it to the river. The wastewater utility also operates and maintains 1,500 miles (2,400 km) of sanitary sewer and pumping stations, 38 miles (61 km) of intercepting sewer lines, and the Shockoe Retention Basin, a 44-million-gallon stormwater reservoir used during heavy rains.
How many kilometers of sewer lines exist in Richmond?
A: 61

Naturally occurring glass, especially the volcanic glass obsidian, has been used by many Stone Age societies across the globe for the production of sharp cutting tools and, due to its limited source areas, was extensively traded. But in general, archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or ancient Egypt. The earliest known glass objects, of the mid third millennium BCE, were beads, perhaps initially created as accidental by-products of metal-working (slags) or during the production of faience, a pre-glass vitreous material made by a process similar to glazing.
What was obsidian used to make in falence processes?
A:
