Problem: Germans:

Since the 2006 FIFA World Cup, the internal and external evaluation of Germany's national image has changed. In the annual Nation Brands Index global survey, Germany became significantly and repeatedly more highly ranked after the tournament. People in 20 different states assessed the country's reputation in terms of culture, politics, exports, its people and its attractiveness to tourists, immigrants and investments. Germany has been named the world's second most valued nation among 50 countries in 2010. Another global opinion poll, for the BBC, revealed that Germany is recognised for the most positive influence in the world in 2010. A majority of 59% have a positive view of the country, while 14% have a negative view.

Problem: The incentive to use 100% renewable energy, for electricity, transport, or even total primary energy supply globally, has been motivated by global warming and other ecological as well as economic concerns. The Intergovernmental Panel on Climate Change has said that there are few fundamental technological limits to integrating a portfolio of renewable energy technologies to meet most of total global energy demand. In reviewing 164 recent scenarios of future renewable energy growth, the report noted that the majority expected renewable sources to supply more than 17% of total energy by 2030, and 27% by 2050; the highest forecast projected 43% supplied by renewables by 2030 and 77% by 2050. Renewable energy use has grown much faster than even advocates anticipated. At the national level, at least 30 nations around the world already have renewable energy contributing more than 20% of energy supply. Also, Professors S. Pacala and Robert H. Socolow have developed a series of "stabilization wedges" that can allow us to maintain our quality of life while avoiding catastrophic climate change, and "renewable energy sources," in aggregate, constitute the largest number of their "wedges."
Who rejected a series of stabilization wedges?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 2008, Bloomberg claimed child labour in copper and cobalt mines that supplied Chinese companies in Congo. The children are creuseurs, that is they dig the ore by hand, carry sacks of ores on their backs, and these are then purchased by these companies. Over 60 of Katanga's 75 processing plants are owned by Chinese companies and 90 percent of the region's minerals go to China. An African NGO report claimed 80,000 child labourers under the age of 15, or about 40% of all miners, were supplying ore to Chinese companies in this African region. Amnesty International alleged in 2016 that some cobalt sold by Congo Dongfang Mining was produced by child labor, and that it was being used in lithium-ion batteries powering electric cars and mobile devices worldwide.
What percent of materials go to China?
A: 90 percent

Context and question: A number of theories have been proposed regarding Avicenna's madhab (school of thought within Islamic jurisprudence). Medieval historian Zahir al-din al-Bayhaqi (d. 1169) considered Avicenna to be a follower of the Brethren of Purity. On the other hand, Dimitri Gutas along with Aisha Khan and Jules J. Janssens demonstrated that Avicenna was a Sunni Hanafi. However, the 14th cenutry Shia faqih Nurullah Shushtari according to Seyyed Hossein Nasr, maintained that he was most likely a Twelver Shia. Conversely, Sharaf Khorasani, citing a rejection of an invitation of the Sunni Governor Sultan Mahmoud Ghazanavi by Avicenna to his court, believes that Avicenna was an Ismaili. Similar disagreements exist on the background of Avicenna's family, whereas some writers considered them Sunni, some more recent writers contested that they were Shia.
Who thought that Avicenna was a Brethren of Purity follower?
Answer: Medieval historian Zahir al-din al-Bayhaqi

Question: The term Hokkien (; hkkn) is itself a term not used in Chinese to refer to the dialect, as it simply means Fujian province. In Chinese linguistics, these dialects are known by their classification under the Quanzhang Division (Chinese: ; pinyin: Quanzhang pian) of Min Nan, which comes from the first characters of the two main Hokkien urban centers Quanzhou and Zhangzhou. The variety is also known by other terms such as the more general Min Nan (traditional Chinese: , ; simplified Chinese: , ; pinyin: Minnanyu, Minnanhua; Peh-oe-ji: Ban-lam-gi,Ban-lam-oe) or Southern Min, and Fulaohua (traditional Chinese: ; simplified Chinese: ; pinyin: Fulaohua; Peh-oe-ji: Ho-lo-oe). The term Hokkien (Chinese: ; Peh-oe-ji: hok-kian oe;Tai-lo:Hok-kian-ue), on the other hand, is used commonly in South East Asia to refer to Min-nan dialects.
Is there an answer to this question: What classification system does the term Hokkien come from?

Answer: unanswerable

Problem: Steven Spielberg:
