Input: Read this: During the last century, decreases in biodiversity have been increasingly observed. In 2007, German Federal Environment Minister Sigmar Gabriel cited estimates that up to 30% of all species will be extinct by 2050. Of these, about one eighth of known plant species are threatened with extinction. Estimates reach as high as 140,000 species per year (based on Species-area theory). This figure indicates unsustainable ecological practices, because few species emerge each year.[citation needed] Almost all scientists acknowledge that the rate of species loss is greater now than at any time in human history, with extinctions occurring at rates hundreds of times higher than background extinction rates. As of 2012, some studies suggest that 25% of all mammal species could be extinct in 20 years.
Question: Who is the German Federal Environment Minister?

Output: Sigmar Gabriel

QUES: The inventor Nicephore Niepce produced the first permanent photograph on a polished pewter plate in Paris in 1825, and then developed the process with Louis Daguerre. The work of Etienne-Jules Marey in the 1880s contributed considerably to the development of modern photography. Photography came to occupy a central role in Parisian Surrealist activity, in the works of Man Ray and Maurice Tabard. Numerous photographers achieved renown for their photography of Paris, including Eugene Atget, noted for his depictions of street scenes, Robert Doisneau, noted for his playful pictures of people and market scenes (among which Le baiser de l'hotel de ville has became iconic of the romantic vision of Paris), Marcel Bovis, noted for his night scenes, and others such as Jacques-Henri Lartigue and Cartier-Bresson. Poster art also became an important art form in Paris in the late nineteenth century, through the work of Henri de Toulouse-Lautrec, Jules Cheret, Eugene Grasset, Adolphe Willette, Pierre Bonnard, Georges de Feure, Henri-Gabriel Ibels, Gavarni, and Alphonse Mucha.

When did poster art become an important art form?
What is the answer?
ANS: late nineteenth century

QUES: The gyromagnetic ratio is the constant of proportionality between the frequency of nuclear magnetic resonance (or electron paramagnetic resonance for electrons) and the applied magnetic field B: = B. It is difficult to measure gyromagnetic ratios precisely because of the difficulties in precisely measuring B, but the value for protons in water at 7002298150000000000♠️25 C is known to better than one part per million. The protons are said to be "shielded" from the applied magnetic field by the electrons in the water molecule, the same effect that gives rise to chemical shift in NMR spectroscopy, and this is indicated by a prime on the symbol for the gyromagnetic ratio, p. The gyromagnetic ratio is related to the shielded proton magnetic moment p, the spin number I (I = 12 for protons) and the reduced Planck constant.
What ratio is the difference of proportionality between the frequency of nuclear magnetic resonance (or electron paramagnetic resonance for electrons) and the applied magnetic field?

ANS: unanswerable

There were 13 finalists this season, but two were eliminated in the first result show of the finals. A new feature introduced was the "Judges' Save", and Matt Giraud was saved from elimination at the top seven by the judges when he received the fewest votes. The next week, Lil Rounds and Anoop Desai were eliminated.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many contestants were sent home during the first week of finals?
Ah, so.. two

Question: New York is a global hub of international business and commerce. In 2012, New York City topped the first Global Economic Power Index, published by The Atlantic (to be differentiated from a namesake list published by the Martin Prosperity Institute), with cities ranked according to criteria reflecting their presence on similar lists as published by other entities. The city is a major center for banking and finance, retailing, world trade, transportation, tourism, real estate, new media as well as traditional media, advertising, legal services, accountancy, insurance, theater, fashion, and the arts in the United States; while Silicon Alley, metonymous for New York's broad-spectrum high technology sphere, continues to expand. The Port of New York and New Jersey is also a major economic engine, handling record cargo volume in the first half of 2014.
Try to answer this question if possible: Who created the Global Economic Power Index that ranked New York first?
Answer: The Atlantic

QUES: During the Hundred Years' War, the army of the Duke of Burgundy and a force of about two hundred English soldiers occupied Paris from May 1420 until 1436. They repelled an attempt by Joan of Arc to liberate the city in 1429. A century later, during the French Wars of Religion, Paris was a stronghold of the Catholic League. On 24 August 1572, Paris was the site of the St. Bartholomew's Day massacre, when thousands of French Protestants were killed. The last of these wars, the eighth one, ended in 1594, after Henri IV had converted to Catholicism and was finally able to enter Paris as he supposedly declared Paris vaut bien une messe ("Paris is well worth a Mass"). The city had been neglected for decades; by the time of his assassination in 1610, Henry IV had rebuilt the Pont Neuf, the first Paris bridge with sidewalks and not lined with buildings, linked with a new wing the Louvre to the Tuileries Palace, and created the first Paris residential square, the Place Royale, now Place des Vosges.
Who tried to liberate the city in 1429?

ANS:
Joan of Arc
