Question: Brasília has a tropical savanna climate (Aw) according to the Köppen 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).
Is there an answer to this question: What climate type does Brasilia have?

Answer: tropical savanna climate (Aw)


Question: The city's population increased more than sixfold during the first half of the 20th century, fed largely by an influx of European, Middle Eastern (Lebanese, Assyrian/Chaldean), and Southern migrants to work in the burgeoning automobile industry. In 1940, Whites were 90.4% of the city's population. Since 1950 the city has seen a major shift in its population to the suburbs. In 1910, fewer than 6,000 blacks called the city home; in 1930 more than 120,000 blacks lived in Detroit. The thousands of African Americans who came to Detroit were part of the Great Migration of the 20th century.
Is there an answer to this question: Where did the population of Detroit shift to in the second half of the 20th century?

Answer: suburbs


Question: Primary resistance occurs when a person becomes infected with a resistant strain of TB. A person with fully susceptible MTB may develop secondary (acquired) resistance during therapy because of inadequate treatment, not taking the prescribed regimen appropriately (lack of compliance), or using low-quality medication. Drug-resistant TB is a serious public health issue in many developing countries, as its treatment is longer and requires more expensive drugs. MDR-TB is defined as resistance to the two most effective first-line TB drugs: rifampicin and isoniazid. Extensively drug-resistant TB is also resistant to three or more of the six classes of second-line drugs. Totally drug-resistant TB is resistant to all currently used drugs. It was first observed in 2003 in Italy, but not widely reported until 2012, and has also been found in Iran and India. Bedaquiline is tentatively supported for use in multiple drug-resistant TB.
Is there an answer to this question: When was MDR-TB first observed?

Answer: unanswerable


Question: First recognized in 1900 by Max Planck, it was originally the proportionality constant between the minimal increment of energy, E, of a hypothetical electrically charged oscillator in a cavity that contained black body radiation, and the frequency, f, of its associated electromagnetic wave. In 1905 the value E, the minimal energy increment of a hypothetical oscillator, was theoretically associated by Einstein with a "quantum" or minimal element of the energy of the electromagnetic wave itself. The light quantum behaved in some respects as an electrically neutral particle, as opposed to an electromagnetic wave. It was eventually called the photon.
Is there an answer to this question: What is the simple name given to the dark quantum today?
