Problem: Hyderabad:

Hyderabad's role in the pearl trade has given it the name "City of Pearls" and up until the 18th century, the city was also the only global trading centre for large diamonds. Industrialisation began under the Nizams in the late 19th century, helped by railway expansion that connected the city with major ports. From the 1950s to the 1970s, Indian enterprises, such as Bharat Heavy Electricals Limited (BHEL), Nuclear Fuel Complex (NFC), National Mineral Development Corporation (NMDC), Bharat Electronics (BEL), Electronics Corporation of India Limited (ECIL), Defence Research and Development Organisation (DRDO), Hindustan Aeronautics Limited (HAL), Centre for Cellular and Molecular Biology (CCMB), Centre for DNA Fingerprinting and Diagnostics (CDFD), State Bank of Hyderabad (SBH) and Andhra Bank (AB) were established in the city. The city is home to Hyderabad Securities formerly known as Hyderabad Stock Exchange (HSE), and houses the regional office of the Securities and Exchange Board of India (SEBI). In 2013, the Bombay Stock Exchange (BSE) facility in Hyderabad was forecast to provide operations and transactions services to BSE-Mumbai by the end of 2014. The growth of the financial services sector has helped Hyderabad evolve from a traditional manufacturing city to a cosmopolitan industrial service centre. Since the 1990s, the growth of information technology (IT), IT-enabled services (ITES), insurance and financial institutions has expanded the service sector, and these primary economic activities have boosted the ancillary sectors of trade and commerce, transport, storage, communication, real estate and retail.

A: From the 1950s to the 1970s

Problem: The word "mammal" is modern, from the scientific name Mammalia coined by Carl Linnaeus in 1758, derived from the Latin mamma ("teat, pap"). All female mammals nurse their young with milk, which is secreted from special glands, the mammary glands. According to Mammal Species of the World, 5,416 species were known in 2006. These were grouped in 1,229 genera, 153 families and 29 orders. In 2008 the IUCN completed a five-year, 1,700-scientist Global Mammal Assessment for its IUCN Red List, which counted 5,488 accepted species.

Context and 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.
When did Max Planck first recognize the value of the Planck constant?
Answer: 1900

Question: The impressive, costly, and centralised rites to the deities of the Roman state were vastly outnumbered in everyday life by commonplace religious observances pertaining to an individual's domestic and personal deities, the patron divinities of Rome's various neighborhoods and communities, and the often idiosyncratic blends of official, unofficial, local and personal cults that characterised lawful Roman religion. In this spirit, a provincial Roman citizen who made the long journey from Bordeaux to Italy to consult the Sibyl at Tibur did not neglect his devotion to his own goddess from home:
Is there an answer to this question: Who made the choices of personal religious practices in Rome?

Problem: Carnival:

The Carnival continued its evolution in small/unimportant towns out of view of the rulers. The result was the uninterrupted celebration of Carnival festivals in Barranquilla (see Barranquilla's Carnival) now recognized as one of the Masterpieces of the Oral and Intangible Heritage of Humanity. The Barranquilla Carnival includes several parades on Friday and Saturday nights beginning on 11 January and ending with a six-day non-stop festival, beginning the Wednesday prior to Ash Wednesday and ending Tuesday midnight. Other celebrations occur in villages along the lower Magdalena River in northern Colombia, and in Pasto, Narino (see Blacks and Whites' Carnival) in the south of the country. In the early 20th century, attempts to introduce Carnival in Bogota were rejected by the government. The Bogota Carnival was renewed in the 21st century.

Where did the Carnival gestate out of the purview of rules?

A:
in small/unimportant towns
