Input: Article: The first hydrogen-filled balloon was invented by Jacques Charles in 1783. Hydrogen provided the lift for the first reliable form of air-travel following the 1852 invention of the first hydrogen-lifted airship by Henri Giffard. German count Ferdinand von Zeppelin promoted the idea of rigid airships lifted by hydrogen that later were called Zeppelins; the first of which had its maiden flight in 1900. Regularly scheduled flights started in 1910 and by the outbreak of World War I in August 1914, they had carried 35,000 passengers without a serious incident. Hydrogen-lifted airships were used as observation platforms and bombers during the war.

Now answer this question: What year was hydrogen filled balloons invented?

Output: 1783


Article: The immediate cause of the war resided in the candidacy of a Leopold of Hohenzollern-Sigmaringen, a Prussian prince, to the throne of Spain. France feared encirclement by an alliance between Prussia and Spain. The Hohenzollern prince's candidacy was withdrawn under French diplomatic pressure, but Otto von Bismarck goaded the French into declaring war by altering a telegram sent by William I. Releasing the Ems Dispatch to the public, Bismarck made it sound as if the king had treated the French envoy in a demeaning fashion, which inflamed public opinion in France.

Question: What was the name of the famous telelgram?
Ans: Ems Dispatch

The problem: Answer a question about this article:
For collectable or nostalgia purposes, or for the benefit of higher-quality audio playback provided by the 78 rpm speed with newer vinyl records and their lightweight stylus pickups, a small number of 78 rpm records have been released since the major labels ceased production. One of the first attempts at this was in the 1950s, when inventor Ewing Dunbar Nunn founded the label Audiophile Records, which released, in addition to standard 33 1/3 rpm LPs, 78 rpm-mastered albums that were microgroove and pressed on vinyl (as opposed to traditional 78s, with their shellac composition and wider 3-mil sized grooves). This was done by the label mainly to take advantage of the wider audio frequency response that faster speeds like 78 rpm can provide for vinyl microgroove records, hence the label's name (obviously catering to the audiophiles of the 1950s "hi-fi" era, when stereo gear could provide a much wider range of audio than before). Also in the late 1950s, Bell Records released a few budget-priced 7" microgrooved records at 78 rpm.
What are reasons for recent releases of 78 rpm speed vinyls?
****
The answer: collectable or nostalgia purposes


Problem: Please answer a question about the following article about Multiracial American:
Some multiracial individuals feel marginalized by U.S. society. For example, when applying to schools or for a job, or when taking standardized tests, Americans are sometimes asked to check boxes corresponding to race or ethnicity. Typically, about five race choices are given, with the instruction to "check only one." While some surveys offer an "other" box, this choice groups together individuals of many different multiracial types (ex: European Americans/African-Americans are grouped with Asian/Native American Indians).
What does the "other" box do?
A: groups together individuals of many different multiracial types


Question: Read this and answer the question

St Helena has long been known for its high proportion of endemic birds and vascular plants. The highland areas contain most of the 400 endemic species recognised to date. Much of the island has been identified by BirdLife International as being important for bird conservation, especially the endemic Saint Helena plover or wirebird, and for seabirds breeding on the offshore islets and stacks, in the north-east and the south-west Important Bird Areas. On the basis of these endemics and an exceptional range of habitats, Saint Helena is on the United Kingdom's tentative list for future UNESCO World Heritage Sites.

Saint Helena has a high proportion of what kind of birds?
Answer:
endemic
