Problem: Question: "How much % electricty did the EU want to be renewable?" Context: "Setting national renewable energy targets can be an important part of a renewable energy policy and these targets are usually defined as a percentage of the primary energy and/or electricity generation mix. For example, the European Union has prescribed an indicative renewable energy target of 12 per cent of the total EU energy mix and 22 per cent of electricity consumption by 2010. National targets for individual EU Member States have also been set to meet the overall target. Other developed countries with defined national or regional targets include Australia, Canada, Israel, Japan, Korea, New Zealand, Norway, Singapore, Switzerland, and some US States." Answer:

A: 22

Problem: Question: "Along with the creator of the Gregorian calendar, who else realized the ancient tables providing the sun's mean longitude were inconsistent?" 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." Answer:

A: Tycho Brahe

Problem: Question: "If the number of remaining Han treatises is one-third of the number of Han Chapters on the Mathematical Art, how many treatises remain?" Context: "Three Han mathematical treatises still exist. These are the Book on Numbers and Computation, the Arithmetical Classic of the Gnomon and the Circular Paths of Heaven and the Nine Chapters on the Mathematical Art. Han-era mathematical achievements include solving problems with right-angle triangles, square roots, cube roots, and matrix methods, finding more accurate approximations for pi, providing mathematical proof of the Pythagorean theorem, use of the decimal fraction, Gaussian elimination to solve linear equations, and continued fractions to find the roots of equations." Answer:

A: Three

Problem: Question: "Who wrote about the relations with the Karmapa hierarchs?" Context: "Despite this glowing message by the Emperor, Chan writes that a year later in 1446, the Ming court cut off all relations with the Karmapa hierarchs. Until then, the court was unaware that Deshin Shekpa had died in 1415. The Ming court had believed that the representatives of the Karma Kagyu who continued to visit the Ming capital were sent by the Karmapa." Answer:

A:
Chan
