Input: Read this: By the early 20th century balloon, or airship, guns, for land and naval use were attracting attention. Various types of ammunition were proposed, high explosive, incendiary, bullet-chains, rod bullets and shrapnel. The need for some form of tracer or smoke trail was articulated. Fuzing options were also examined, both impact and time types. Mountings were generally pedestal type, but could be on field platforms. Trials were underway in most countries in Europe but only Krupp, Erhardt, Vickers Maxim, and Schneider had published any information by 1910. Krupp's designs included adaptations of their 65 mm 9-pounder, a 75 mm 12-pounder, and even a 105 mm gun. Erhardt also had a 12-pounder, while Vickers Maxim offered a 3-pounder and Schneider a 47 mm. The French balloon gun appeared in 1910, it was an 11-pounder but mounted on a vehicle, with a total uncrewed weight of 2 tons. However, since balloons were slow moving, sights were simple. But the challenges of faster moving airplanes were recognised.
Question: What gun made the scene in 1910?

Output: French balloon gun


QUES: Drying involves using air and/or heat to remove water from the paper sheets; in the earliest days of paper making this was done by hanging the sheets like laundry; in more modern times various forms of heated drying mechanisms are used. On the paper machine the most common is the steam heated can dryer. These can reach temperatures above 200 °F (93 °C) and are used in long sequences of more than 40 cans; where the heat produced by these can easily dry the paper to less than 6% moisture.

What involves using air and heat to add water to the paper sheets?

QUES: Counting shipping as quasi-exports and in terms of monetary value, Greece ranked 4th globally in 2011 having "exported" shipping services worth 17,704.132 million $; only Denmark, Germany and South Korea ranked higher during that year. Similarly counting shipping services provided to Greece by other countries as quasi-imports and the difference between "exports" and "imports" as a "trade balance", Greece in 2011 ranked in the latter second behind Germany, having "imported" shipping services worth 7,076.605 million US$ and having run a "trade surplus" of 10,712.342 million US$.
When counting shipping as quasi-exports and in terms of monetary value, what is Greece's local rank?

Some historians estimate the number of magnates as 1% of the number of szlachta. Out of approx. one million szlachta, tens of thousands of families, only 200–300 persons could be classed as great magnates with country-wide possessions and influence, and 30–40 of them could be viewed as those with significant impact on Poland's politics.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Out of one million szlachtas how many were magnates? 
Ah, so.. 200–300


Question: The formalist definition is that the history of "literature" foregrounds poetic effects; it is the "literariness" or "poeticity" of literature that distinguishes it from ordinary speech or other kinds of writing (e.g., journalism). Jim Meyer considers this a useful characteristic in explaining the use of the term to mean published material in a particular field (e.g., "scientific literature"), as such writing must use language according to particular standards. The problem with the formalist definition is that in order to say that literature deviates from ordinary uses of language, those uses must first be identified; this is difficult because "ordinary language" is an unstable category, differing according to social categories and across history.
Try to answer this question if possible: Jim Meyer considers what term to be useful in explaining scientific literature?
Answer: unanswerable


Question: The headquarters of the MoD are in Whitehall and are now known as Main Building. This structure is neoclassical in style and was originally built between 1938 and 1959 to designs by Vincent Harris to house the Air Ministry and the Board of Trade. The northern entrance in Horse Guards Avenue is flanked by two monumental statues, Earth and Water, by Charles Wheeler. Opposite stands the Gurkha Monument, sculpted by Philip Jackson and unveiled in 1997 by Queen Elizabeth II. Within it is the Victoria Cross and George Cross Memorial, and nearby are memorials to the Fleet Air Arm and RAF (to its east, facing the riverside). A major refurbishment of the building was completed under a PFI contract by Skanska in 2004.
Try to answer this question if possible: In what city are the headquarters of the MoD?
