Q: Extract the answer to the question from the following context. Question: How is price stability defined? Context: The primary objective of the European Central Bank, as laid down in Article 127(1) of the Treaty on the Functioning of the European Union, is to maintain price stability within the Eurozone. The Governing Council in October 1998 defined price stability as inflation of under 2%, "a year-on-year increase in the Harmonised Index of Consumer Prices (HICP) for the euro area of below 2%" and added that price stability "was to be maintained over the medium term". (Harmonised Index of Consumer Prices) Unlike for example the United States Federal Reserve Bank, the ECB has only one primary objective but this objective has never been defined in statutory law, and the HICP target can be termed ad-hoc.
A: inflation of under 2%

Q: Extract the answer to the question from the following context. Question: Other than Fish and Wildlife Service, which agency is tasked with creating a recovery plan for endangered species? Context: Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) are required to create an Endangered Species Recovery Plan outlining the goals, tasks required, likely costs, and estimated timeline to recover endangered species (i.e., increase their numbers and improve their management to the point where they can be removed from the endangered list). The ESA does not specify when a recovery plan must be completed. The FWS has a policy specifying completion within three years of the species being listed, but the average time to completion is approximately six years. The annual rate of recovery plan completion increased steadily from the Ford administration (4) through Carter (9), Reagan (30), Bush I (44), and Clinton (72), but declined under Bush II (16 per year as of 9/1/06).
A: National Marine Fisheries Service (NMFS)

Q: Extract the answer to the question from the following context. Question: Along with information about the mean tropical year, what provided information about the sun's mean longitude? Context: Ancient tables provided the sun's mean longitude. Christopher Clavius, the architect of the Gregorian calendar, noted that the tables agreed neither on the time when the sun passed through the vernal equinox nor on the length of the mean tropical year. Tycho Brahe also noticed discrepancies. The Gregorian leap year rule (97 leap years in 400 years) was put forward by Petrus Pitatus of Verona in 1560. He noted that it is consistent with the tropical year of the Alfonsine tables and with the mean tropical year of Copernicus (De revolutionibus) and Reinhold (Prutenic tables). The three mean tropical years in Babylonian sexagesimals as the excess over 365 days (the way they would have been extracted from the tables of mean longitude) were 14,33,9,57 (Alphonsine), 14,33,11,12 (Copernicus) and 14,33,9,24 (Reinhold). All values are the same to two places (14:33) and this is also the mean length of the Gregorian year. Thus Pitatus' solution would have commended itself to the astronomers.
A:
time when the sun passed through the vernal equinox
