The problem: Answer a question about this article:
The core technology used in a videoconferencing system is digital compression of audio and video streams in real time. The hardware or software that performs compression is called a codec (coder/decoder). Compression rates of up to 1:500 can be achieved. The resulting digital stream of 1s and 0s is subdivided into labeled packets, which are then transmitted through a digital network of some kind (usually ISDN or IP). The use of audio modems in the transmission line allow for the use of POTS, or the Plain Old Telephone System, in some low-speed applications, such as videotelephony, because they convert the digital pulses to/from analog waves in the audio spectrum range.
What do POTS do?
****
The answer: convert the digital pulses to/from analog waves

Napoleon III responded with a show of force, sending the ship of the line Charlemagne to the Black Sea. This action was a violation of the London Straits Convention.:104:19 Thus, France's show of force presented a real threat, and when combined with aggressive diplomacy and money, induced the Ottoman Sultan Abdülmecid I to accept a new treaty, confirming France and the Roman Catholic Church as the supreme Christian authority with control over the Roman Catholic holy places and possession of the keys to the Church of the Nativity, previously held by the Greek Orthodox Church.:20
Sending a ship to the Black Sea violated the terms made during what agreement?
****
The answer: London Straits Convention


The problem: Answer a question about this article:
Others have argued that excessive regulation suppresses therapeutic innovation, and that the current cost of regulator-required clinical trials prevents the full exploitation of new genetic and biological knowledge for the treatment of human disease. A 2012 report by the President's Council of Advisors on Science and Technology made several key recommendations to reduce regulatory burdens to new drug development, including 1) expanding the FDA's use of accelerated approval processes, 2) creating an expedited approval pathway for drugs intended for use in narrowly defined populations, and 3) undertaking pilot projects designed to evaluate the feasibility of a new, adaptive drug approval process.
What can be used to evaluate new approval processes?
****
The answer: pilot projects


The problem: Answer a question about this article:
The earliest known chemical evidence of barley beer dates to circa 3500–3100 BC from the site of Godin Tepe in the Zagros Mountains of western Iran. Some of the earliest Sumerian writings contain references to beer; examples include a prayer to the goddess Ninkasi, known as "The Hymn to Ninkasi", which served as both a prayer as well as a method of remembering the recipe for beer in a culture with few literate people, and the ancient advice (Fill your belly. Day and night make merry) to Gilgamesh, recorded in the Epic of Gilgamesh, by the ale-wife Siduri may, at least in part, have referred to the consumption of beer. The Ebla tablets, discovered in 1974 in Ebla, Syria, show that beer was produced in the city in 2500 BC. A fermented beverage using rice and fruit was made in China around 7000 BC. Unlike sake, mould was not used to saccharify the rice (amylolytic fermentation); the rice was probably prepared for fermentation by mastication or malting.
What country are the Zargos Mountains located in?
****
The answer:
Iran
