Problem: Affirmative action in the United States:

The controversy surrounding affirmative action's effectiveness is based on the idea of class inequality. Opponents of racial affirmative action argue that the program actually benefits middle- and upper-class African Americans and Hispanic Americans at the expense of lower-class European Americans and Asian Americans. This argument supports the idea of class-based affirmative action. America's poor is disproportionately made up of people of color, so class-based affirmative action would disproportionately help people of color. This would eliminate the need for race-based affirmative action as well as reducing any disproportionate benefits for middle- and upper-class people of color.

Which idea is the controversy of affirmative action primarily based upon?
---
A: class inequality


Problem: The New Zealand police attempted to arrest one of the leaders in the demonstration. When he resisted, a struggle developed between the police and the Mau. The officers began to fire randomly into the crowd and a Lewis machine gun, mounted in preparation for this demonstration, was used to disperse the demonstrators. Chief Tamasese was shot from behind and killed while trying to bring calm and order to the Mau demonstrators, screaming "Peace, Samoa". Ten others died that day and approximately 50 were injured by gunshot wounds and police batons. That day would come to be known in Samoa as Black Saturday. The Mau grew, remaining steadfastly non-violent, and expanded to include a highly influential women's branch.
What do Samoans call the historical day of the Mau demonstration?
---
Answer: Black Saturday

The territory that now constitutes Tajikistan was previously home to several ancient cultures, including the city of Sarazm of the Neolithic and the Bronze Age, and was later home to kingdoms ruled by people of different faiths and cultures, including the Oxus civilization, Andronovo culture, Buddhism, Nestorian Christianity, Zoroastrianism, and Manichaeism. The area has been ruled by numerous empires and dynasties, including the Achaemenid Empire, Sassanian Empire, Hephthalite Empire, Samanid Empire, Mongol Empire, Timurid dynasty, and the Russian Empire. As a result of the breakup of the Soviet Union, Tajikistan became an independent nation in 1991. A civil war was fought almost immediately after independence, lasting from 1992 to 1997. Since the end of the war, newly established political stability and foreign aid have allowed the country's economy to grow.
As a result of the breakup of Japan, Tajikistan became what?

Question: The first practical ICs were invented by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor. Kilby recorded his initial ideas concerning the integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958. In his patent application of 6 February 1959, Kilby described his new device as "a body of semiconductor material ... wherein all the components of the electronic circuit are completely integrated". Noyce also came up with his own idea of an integrated circuit half a year later than Kilby. His chip solved many practical problems that Kilby's had not. Produced at Fairchild Semiconductor, it was made of silicon, whereas Kilby's chip was made of germanium.
Is there an answer to this question: Noyce's IC was made up of what material?

Answer: silicon
