In this task you will be given a text passage from a trivia quiz. You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.

[Q]: Ninhydrin forms a Schiff base with this chemical, resulting in a hue known as Ruhemanns purple. The Birch reduction takes place in a liquid substrate of it, the reason it is common in methamphetamine labs. The Kjeldahl method uses this molecule as an end-product to measure the amount of nitrogen in a sample, and it is oxidized in the first step of a nitric acid forming procedure, the Ostwald process. For 10 points, name this weak base found in fertilizers, formed by combining hydrogen and nitrogen in a three-to-one ratio in the Haber process.
[A]: Science


[Q]: Even though the voting in this nation occurred on March 29, the results have still not been provided, especially since a High Court hearing has officially requested a recount in a number of provinces. The election has been fraught with bad news for the incumbent, with a split ruling party divided through the rise of Simba Makoni and the rise in inflation far above 1,000%. Thus, Morgan Tsvangirais MDC party has been widely declared the winners both in the parliamentary and presidential struggle. FTP; name this nation who may soon see the unseating of their current ruler, Robert Mugabe.
[A]: History


[Q]: This kind of molecule is detected by the CIDNP effect in NMR spectroscopy, and examples of them include the nitroso component of Fremy's salt and TEMPO. They take part in reactions like NMP, ATRP, and RAFT, or reversible addition-fragmentation chain transfer. One of these based on naphthalene shows up as five quintets in ESR spectroscopy, which is especially suited to their study. The most prominent biological one is counteracted by its namesake dismutase, superoxide, and the anti-Markovnikov addition of HBr to an alkene can occur via one of these. Other reactions involving them tend to consist of initiation, propagation, and termination. FTP, name these highly reactive molecules characterized by an unpaired electron in their outer shell.
