Problem: The Han dynasty (Chinese: 漢朝; pinyin: Hàn cháo) was the second imperial dynasty of China, preceded by the Qin dynasty (221–207 BC) and succeeded by the Three Kingdoms period (220–280 AD). Spanning over four centuries, the Han period is considered a golden age in Chinese history. To this day, China's majority ethnic group refers to itself as the "Han people" and the Chinese script is referred to as "Han characters". It was founded by the rebel leader Liu Bang, known posthumously as Emperor Gaozu of Han, and briefly interrupted by the Xin dynasty (9–23 AD) of the former regent Wang Mang. This interregnum separates the Han dynasty into two periods: the Western Han or Former Han (206 BC – 9 AD) and the Eastern Han or Later Han (25–220 AD).
What dynasty came before the Han dynasty?

Answer: Qin


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
As the 20th century came to a close, Gaddafi increasingly rejected Arab nationalism, frustrated by the failure of his Pan-Arab ideals; instead he turned to Pan-Africanism, emphasising Libya's African identity. From 1997 to 2000, Libya initiated cooperative agreements or bilateral aid arrangements with 10 African states, and in 1999 joined the Community of Sahel-Saharan States. In June 1999, Gaddafi visited Mandela in South Africa, and the following month attended the OAU summit in Algiers, calling for greater political and economic integration across the continent and advocating the foundation of a United States of Africa. He became one of the founders of the African Union (AU), initiated in July 2002 to replace the OAU; at the opening ceremonies, he proclaimed that African states should reject conditional aid from the developed world, a direct contrast to the message of South African President Thabo Mbeki. At the third AU summit, held in Libya in July 2005, he called for a greater level of integration, advocating a single AU passport, a common defence system and a single currency, utilising the slogan: "The United States of Africa is the hope." In June 2005, Libya joined the Common Market for Eastern and Southern Africa (COMESA), and in August 2008 Gaddafi was proclaimed "King of Kings" by an assembled committee of traditional African leaders. On 1 February 2009, his "coronation ceremony" was held in Addis Ababa, Ethiopia, coinciding with Gaddafi's election as AU chairman for a year.
What organization was founded in July of 2002?
A: African Union


Context and question: The FAA gradually assumed additional functions. The hijacking epidemic of the 1960s had already brought the agency into the field of civil aviation security. In response to the hijackings on September 11, 2001, this responsibility is now primarily taken by the Department of Homeland Security. The FAA became more involved with the environmental aspects of aviation in 1968 when it received the power to set aircraft noise standards. Legislation in 1970 gave the agency management of a new airport aid program and certain added responsibilities for airport safety. During the 1960s and 1970s, the FAA also started to regulate high altitude (over 500 feet) kite and balloon flying.
What epidemic did the FAA have to handle in the 1960s?
Answer: hijacking


Question: As the playing of gramophone records causes gradual degradation of the recording, they are best preserved by transferring them onto other media and playing the records as rarely as possible. They need to be stored on edge, and do best under environmental conditions that most humans would find comfortable. The medium needs to be kept clean, but alcohol should only be used on PVC or optical media, not on 78s.[citation needed] The equipment for playback of certain formats (e.g., 16 and 78 rpm) is manufactured only in small quantities, leading to increased difficulty in finding equipment to play the recordings.
Is there an answer to this question: Should alcohol be used to clean gramophone recordings?

Answer: alcohol should only be used on PVC or optical media


Water splitting, in which water is decomposed into its component protons, electrons, and oxygen, occurs in the light reactions in all photosynthetic organisms. Some such organisms, including the alga Chlamydomonas reinhardtii and cyanobacteria, have evolved a second step in the dark reactions in which protons and electrons are reduced to form H2 gas by specialized hydrogenases in the chloroplast. Efforts have been undertaken to genetically modify cyanobacterial hydrogenases to efficiently synthesize H2 gas even in the presence of oxygen. Efforts have also been undertaken with genetically modified alga in a bioreactor.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How are these gases formed?
Ah, so..
by specialized hydrogenases in the chloroplast
