Input: Read this: After the setback at Aspern-Essling, Napoleon took more than six weeks in planning and preparing for contingencies before he made another attempt at crossing the Danube. From 30 June to the early days of July, the French recrossed the Danube in strength, with more than 180,000 troops marching across the Marchfeld towards the Austrians. Charles received the French with 150,000 of his own men. In the ensuing Battle of Wagram, which also lasted two days, Napoleon commanded his forces in what was the largest battle of his career up until then. Neither side made much progress on 5 July, but the 6th produced a definitive outcome. Both sides launched major assaults on their flanks. Austrian attacks against the French left wing looked dangerous initially, but they were all beaten back. Meanwhile, a steady French attack against the Austrian left wing eventually compromised the entire position for Charles. Napoleon finished off the battle with a concentrated central thrust that punctured a hole in the Austrian army and forced Charles to retreat. Austrian losses were very heavy, reaching well over 40,000 casualties. The French were too exhausted to pursue the Austrians immediately, but Napoleon eventually caught up with Charles at Znaim and the latter signed an armistice on 12 July.
Question: Approximately how long did Napoleon take to prepare another Danube crossing after his defeat at Aspern-Essling?

Output: six weeks

Input: Read this: The art of carpet weaving was particularly significant in the Ottoman Empire, carpets having an immense importance both as decorative furnishings, rich in religious and other symbolism, and as a practical consideration, as it was customary to remove one's shoes in living quarters. The weaving of such carpets originated in the nomadic cultures of central Asia (carpets being an easily transportable form of furnishing), and was eventually spread to the settled societies of Anatolia. Turks used carpets, rugs and kilims not just on the floors of a room, but also as a hanging on walls and doorways, where they provided additional insulation. They were also commonly donated to mosques, which often amassed large collections of them.
Question: Which art was important in religious symbolism and as a decoration in the Ottoman empire?

Output: carpet weaving

Input: Read this: National and regional variations also occur within the BBC One and BBC Two schedules. England's BBC One output is split up into fifteen regions (such as South West and East), which exist mainly to produce local news programming, but also occasionally opt out of the network to show programmes of local importance (such as major local events). The other nations of the United Kingdom (Wales, Scotland and Northern Ireland) have been granted more autonomy from the English network; for example, programmes are mostly introduced by local announcers, rather than by those in London. BBC One and BBC Two schedules in the other UK nations can vary immensely from BBC One and BBC Two in England.
Question: What city are the announcers of Wales, Scotland, and Northern Ireland mostly from?

Output: unanswerable

Input: Read this: These areas contain some spectacular scenery as well, as evidenced by such national parks as Yosemite and Mount Rainier. West of the Cascades and Sierra Nevada is a series of valleys, such as the Central Valley in California and the Willamette Valley in Oregon. Along the coast is a series of low mountain ranges known as the Pacific Coast Ranges. Much of the Pacific Northwest coast is inhabited by some of the densest vegetation outside of the Tropics, and also the tallest trees in the world (the Redwoods).
Question: What is the name of the famous valley located in Oregon?

Output:
Willamette Valley
