Problem: Brasilia has a tropical savanna climate (Aw) according to the Koppen system, with two distinct seasons: the rainy season, from October to April, and a dry season, from May to September. The average temperature is 20.6 C (69.1 F). September, at the end of the dry season, has the highest average maximum temperature, 28.3 C (82.9 F), has major and minor lower maximum average temperature, of 25.1 C (77.2 F) and 12.9 C (55.2 F), respectively. Average temperatures from September through March are a consistent 22 C (72 F). With 247.4 mm (9.7 in), January is the month with the highest rainfall of the year, while June is the lowest, with only 8.7 mm (0.3 in).
What is the average maximum temperature in Brasilia in September?

Answer: 28.3 C (82.9 F)

In the context of chemistry, energy is an attribute of a substance as a consequence of its atomic, molecular or aggregate structure. Since a chemical transformation is accompanied by a change in one or more of these kinds of structure, it is invariably accompanied by an increase or decrease of energy of the substances involved. Some energy is transferred between the surroundings and the reactants of the reaction in the form of heat or light; thus the products of a reaction may have more or less energy than the reactants. A reaction is said to be exergonic if the final state is lower on the energy scale than the initial state; in the case of endergonic reactions the situation is the reverse. Chemical reactions are invariably not possible unless the reactants surmount an energy barrier known as the activation energy. The speed of a chemical reaction (at given temperature T) is related to the activation energy E, by the Boltzmann's population factor eE/kT that is the probability of molecule to have energy greater than or equal to E at the given temperature T. This exponential dependence of a reaction rate on temperature is known as the Arrhenius equation.The activation energy necessary for a chemical reaction can be in the form of thermal energy.
What is the exponential independence of a reaction rate on temperature?
A: unanswerable

Context and question: Through publicly funded emergency relief programs concentrating on agricultural land-improvement projects and road construction, the "Erich Koch Plan" for East Prussia allegedly made the province free of unemployment; on August 16, 1933 Koch reported to Hitler that unemployment had been banished entirely from East Prussia, a feat that gained admiration throughout the Reich. Koch's industrialization plans led him into conflict with R. Walther Darre, who held the office of the Reich Peasant Leader (Reichsbauernfuhrer) and Minister of Agriculture. Darre, a neopaganist rural romantic, wanted to enforce his vision of an agricultural East Prussia. When his "Land" representatives challenged Koch's plans, Koch had them arrested.
What religion was Erich Koch?
Answer: unanswerable

Question: The Arena Football League briefly had a two-game exhibition season in the early 2000s, a practice that ended in 2003 with a new television contract. Exhibition games outside of a structured season are relatively common among indoor American football leagues; because teams switch leagues frequently at that level of play, it is not uncommon to see some of the smaller leagues schedule exhibition games against teams that are from another league, about to join the league as a probational franchise, or a semi-pro outdoor team to fill holes in a schedule.
Is there an answer to this question: At what level do teams not switch leagues frequently occur in a walk

Answer: unanswerable

Chopin's mazurkas and waltzes are all in straightforward ternary or episodic form, sometimes with a coda. The mazurkas often show more folk features than many of his other works, sometimes including modal scales and harmonies and the use of drone basses. However, some also show unusual sophistication, for example Op. 63 No. 3, which includes a canon at one beat's distance, a great rarity in music.
What type of bass do Chopin's mazurkas exhibit?
A:
drone bass
