[Q]: Factories in China often produce what type of gas in their emissions that acts as pollution?, Context: A dense wave of smog began in the Central and Eastern part of China on 2 December 2013 across a distance of around 1,200 kilometres (750 mi), including Tianjin, Hebei, Shandong, Jiangsu, Anhui, Shanghai and Zhejiang. A lack of cold air flow, combined with slow-moving air masses carrying industrial emissions, collected airborne pollutants to form a thick layer of smog over the region. The heavy smog heavily polluted central and southern Jiangsu Province, especially in and around Nanjing, with its AQI pollution Index at "severely polluted" for five straight days and "heavily polluted" for nine. On 3 December 2013, levels of PM2.5 particulate matter average over 943 micrograms per cubic metre, falling to over 338 micrograms per cubic metre on 4 December 2013. Between 3:00 pm, 3 December and 2:00pm, 4 December local time, several expressways from Nanjing to other Jiangsu cities were closed, stranding dozens of passenger buses in Zhongyangmen bus station. From 5 to 6 December, Nanjing issued a red alert for air pollution and closed down all kindergarten through middle schools. Children's Hospital outpatient services increased by 33 percent; general incidence of bronchitis, pneumonia, upper respiratory tract infections significantly increased. The smog dissipated 12 December. Officials blamed the dense pollution on lack of wind, automobile exhaust emissions under low air pressure, and coal-powered district heating system in North China region. Prevailing winds blew low-hanging air masses of factory emissions (mostly SO2) towards China's east coast.
[A]: SO2


[Q]: Who remained under the rule of the Qutb Shahi dyansty?, Context: Established in 1591 by Muhammad Quli Qutb Shah, Hyderabad remained under the rule of the Qutb Shahi dynasty for nearly a century before the Mughals captured the region. In 1724, Mughal viceroy Asif Jah I declared his sovereignty and created his own dynasty, known as the Nizams of Hyderabad. The Nizam's dominions became a princely state during the British Raj, and remained so for 150 years, with the city serving as its capital. The Nizami influence can still be seen in the culture of the Hyderabadi Muslims. The city continued as the capital of Hyderabad State after it was brought into the Indian Union in 1948, and became the capital of Andhra Pradesh after the States Reorganisation Act, 1956. Since 1956, Rashtrapati Nilayam in the city has been the winter office of the President of India. In 2014, the newly formed state of Telangana split from Andhra Pradesh and the city became joint capital of the two states, a transitional arrangement scheduled to end by 2025.
[A]: Hyderabad


[Q]: What social class do both authors claim benefits the least from affirmative action?, Context: Terry Eastland, the author who wrote From Ending Affirmative Action: The Case for Colorblind Justice states, "Most arguments for affirmative action fall into two categories: remedying past discrimination and promoting diversity". Eastland believes that the founders of affirmative action did not anticipate how the benefits of affirmative action would go to those who did not need it, mostly middle class minorities. Additionally, she argues that affirmative action carries with it a stigma that can create feelings of self-doubt and entitlement in minorities. Eastland believes that affirmative action is a great risk that only sometimes pays off, and that without it we would be able to compete more freely with one another. Libertarian economist Thomas Sowell identified what he says are negative results of affirmative action in his book, Affirmative Action Around the World: An Empirical Study. Sowell writes that affirmative action policies encourage non-preferred groups to designate themselves as members of preferred groups [i.e., primary beneficiaries of affirmative action] to take advantage of group preference policies; that they tend to benefit primarily the most fortunate among the preferred group (e.g., upper and middle class blacks), often to the detriment of the least fortunate among the non-preferred groups (e.g., poor white or Asian); that they reduce the incentives of both the preferred and non-preferred to perform at their best – the former because doing so is unnecessary and the latter because it can prove futile – thereby resulting in net losses for society as a whole; and that they engender animosity toward preferred groups as well.:115–147
