Problem: I know that the answer to the question "A calendar that consisted of 365 days was considered to be what type?" is in "The Gregorian calendar is a solar calendar. A regular Gregorian year consists of 365 days, but as in the Julian calendar, in a leap year, a leap day is added to February. In the Julian calendar a leap year occurs every 4 years, but the Gregorian calendar omits 3 leap days every 400 years. In the Julian calendar, this leap day was inserted by doubling 24 February, and the Gregorian reform did not change the date of the leap day. In the modern period, it has become customary to number the days from the beginning of the month, and February 29th is often considered as the leap day. Some churches, notably the Roman Catholic Church, delay February festivals after the 23rd by one day in leap years.". Can you tell me what it is?

A: Gregorian calendar


Problem: I know that the answer to the question "What neighboring location is crucial for the city's water supply?" is in "Melbourne's air quality is generally good and has improved significantly since the 1980s. Like many urban environments, the city faces significant environmental issues, many of them relating to the city's large urban footprint and urban sprawl and the demand for infrastructure and services. One such issue is water usage, drought and low rainfall. Drought in Victoria, low rainfalls and high temperatures deplete Melbourne water supplies and climate change may have a long-term impact on the water supplies of Melbourne. In response to low water supplies and low rainfall due to drought, the government implemented water restrictions and a range of other options including: water recycling schemes for the city, incentives for household water tanks, greywater systems, water consumption awareness initiatives, and other water saving and reuse initiatives; also, in June 2007, the Bracks Government announced that a $3.1 billion Wonthaggi desalination plant would be built on Victoria's south-east coast, capable of treating 150 billion litres of water per year, as well as a 70 km (43 mi) pipeline from the Goulburn area in Victoria's north to Melbourne and a new water pipeline linking Melbourne and Geelong. Both projects are being conducted under controversial Public-Private Partnerships and a multitude of independent reports have found that neither project is required to supply water to the city and that Sustainable Water Management is the best solution. In the meantime, the drought must be weathered.". Can you tell me what it is?

Problem: I know that the answer to the question "Which of the following is not a type of decoder: AC-3, A/V or DTS?" is in "Only one 5.1 surround sound option exists on a given LaserDisc (either Dolby Digital or DTS), so if surround sound is desired, the disc must be matched to the capabilities of the playback equipment (LD Player and Receiver/Decoder) by the purchaser. A fully capable LaserDisc playback system includes a newer LaserDisc player that is capable of playing digital tracks, has a digital optical output for digital PCM and DTS audio, is aware of AC-3 audio tracks, and has an AC-3 coaxial output; an external or internal AC-3 RF demodulator and AC-3 decoder; and a DTS decoder. Many 1990s A/V receivers combine the AC-3 decoder and DTS decoder logic, but an integrated AC-3 demodulator is rare both in LaserDisc players and in later A/V receivers.". Can you tell me what it is?

A: A/V


Problem: I know that the answer to the question "What type of company can gain market exclusivity through the Orphan Drug Act?" is in "There are special rules for certain rare diseases ("orphan diseases") in several major drug regulatory territories. For example, diseases involving fewer than 200,000 patients in the United States, or larger populations in certain circumstances are subject to the Orphan Drug Act.  Because medical research and development of drugs to treat such diseases is financially disadvantageous, companies that do so are rewarded with tax reductions, fee waivers, and market exclusivity on that drug for a limited time (seven years), regardless of whether the drug is protected by patents.".
