[Q]: Passage: In June 2014, state broadcaster China Central Television (CCTV) broadcast a news story further characterizing Windows 8 as a threat to national security. The story featured an interview with Ni Guangnan, who stated that operating systems could aggregate "sensitive user information" that could be used to "understand the conditions and activities of our national economy and society", and alleged that per documents leaked by Edward Snowden, the U.S. government had worked with Microsoft to retrieve encrypted information. Yang Min, a computer scientist at Fudan University, also stated that "the security features of Windows 8 are basically to the benefit of Microsoft, allowing them control of the users' data, and that poses a big challenge to the national strategy for information security." Microsoft denied the claims in a number of posts on the Chinese social network Sina Weibo, which stated that the company had never "assisted any government in an attack of another government or clients" or provided client data to the U.S. government, never "provided any government the authority to directly visit" or placed any backdoors in its products and services, and that it had never concealed government requests for client data. Question: What is the name of the Chinese social network?
[A]: Sina Weibo

[Q]: Passage: Extensive and diverse public spending is, in itself, inherently at risk of cronyism, kickbacks, and embezzlement. Complicated regulations and arbitrary, unsupervised official conduct exacerbate the problem. This is one argument for privatization and deregulation. Opponents of privatization see the argument as ideological. The argument that corruption necessarily follows from the opportunity is weakened by the existence of countries with low to non-existent corruption but large public sectors, like the Nordic countries. These countries score high on the Ease of Doing Business Index, due to good and often simple regulations, and have rule of law firmly established. Therefore, due to their lack of corruption in the first place, they can run large public sectors without inducing political corruption. Recent evidence that takes both the size of expenditures and regulatory complexity into account has found that high-income democracies with more expansive state sectors do indeed have higher levels of corruption. Question: What countries have big public sectors but low corruption?
[A]: Nordic
