Problem: Glass:

From the 19th century, there was a revival in many ancient glass-making techniques including cameo glass, achieved for the first time since the Roman Empire and initially mostly used for pieces in a neo-classical style. The Art Nouveau movement made great use of glass, with René Lalique, Émile Gallé, and Daum of Nancy producing colored vases and similar pieces, often in cameo glass, and also using luster techniques. Louis Comfort Tiffany in America specialized in stained glass, both secular and religious, and his famous lamps. The early 20th-century saw the large-scale factory production of glass art by firms such as Waterford and Lalique. From about 1960 onwards there have been an increasing number of small studios hand-producing glass artworks, and glass artists began to class themselves as in effect sculptors working in glass, and their works as part fine arts.

When did mass production of lamps begin?

Problem: The ESA requires that critical habitat be designated at the time of or within one year of a species being placed on the endangered list. In practice, most designations occur several years after listing. Between 1978 and 1986 the FWS regularly designated critical habitat. In 1986 the Reagan Administration issued a regulation limiting the protective status of critical habitat. As a result, few critical habitats were designated between 1986 and the late 1990s. In the late 1990s and early 2000s, a series of court orders invalidated the Reagan regulations and forced the FWS and NMFS to designate several hundred critical habitats, especially in Hawaii, California and other western states. Midwest and Eastern states received less critical habitat, primarily on rivers and coastlines. As of December, 2006, the Reagan regulation has not yet been replaced though its use has been suspended. Nonetheless, the agencies have generally changed course and since about 2005 have tried to designate critical habitat at or near the time of listing.
How many critical habitats were built between 1978 and 1986?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Several explanations have been offered for Yale’s representation in national elections since the end of the Vietnam War. Various sources note the spirit of campus activism that has existed at Yale since the 1960s, and the intellectual influence of Reverend William Sloane Coffin on many of the future candidates. Yale President Richard Levin attributes the run to Yale’s focus on creating "a laboratory for future leaders," an institutional priority that began during the tenure of Yale Presidents Alfred Whitney Griswold and Kingman Brewster. Richard H. Brodhead, former dean of Yale College and now president of Duke University, stated: "We do give very significant attention to orientation to the community in our admissions, and there is a very strong tradition of volunteerism at Yale." Yale historian Gaddis Smith notes "an ethos of organized activity" at Yale during the 20th century that led John Kerry to lead the Yale Political Union's Liberal Party, George Pataki the Conservative Party, and Joseph Lieberman to manage the Yale Daily News. Camille Paglia points to a history of networking and elitism: "It has to do with a web of friendships and affiliations built up in school." CNN suggests that George W. Bush benefited from preferential admissions policies for the "son and grandson of alumni", and for a "member of a politically influential family." New York Times correspondent Elisabeth Bumiller and The Atlantic Monthly correspondent James Fallows credit the culture of community and cooperation that exists between students, faculty, and administration, which downplays self-interest and reinforces commitment to others.
Why did Richard Brodhead believe there were so many Yale alumni presidential candidates?
A: very strong tradition of volunteerism


Context and question: Like the Speaker of the House, the Minority Leaders are typically experienced lawmakers when they win election to this position. When Nancy Pelosi, D-CA, became Minority Leader in the 108th Congress, she had served in the House nearly 20 years and had served as minority whip in the 107th Congress. When her predecessor, Richard Gephardt, D-MO, became minority leader in the 104th House, he had been in the House for almost 20 years, had served as chairman of the Democratic Caucus for four years, had been a 1988 presidential candidate, and had been majority leader from June 1989 until Republicans captured control of the House in the November 1994 elections. Gephardt's predecessor in the minority leadership position was Robert Michel, R-IL, who became GOP Leader in 1981 after spending 24 years in the House. Michel's predecessor, Republican John Rhodes of Arizona, was elected Minority Leader in 1973 after 20 years of House service.
John Rhodes served as minority leader beginning in what year?
Answer: 1973


Question: During the middle decades of the 18th century, there were several outbreaks of military conflict on the Indian subcontinent, the Carnatic Wars, as the English East India Company (the Company) and its French counterpart, the Compagnie française des Indes orientales, struggled alongside local rulers to fill the vacuum that had been left by the decline of the Mughal Empire. The Battle of Plassey in 1757, in which the British, led by Robert Clive, defeated the Nawab of Bengal and his French allies, left the Company in control of Bengal and as the major military and political power in India. France was left control of its enclaves but with military restrictions and an obligation to support British client states, ending French hopes of controlling India. In the following decades the Company gradually increased the size of the territories under its control, either ruling directly or via local rulers under the threat of force from the British Indian Army, the vast majority of which was composed of Indian sepoys.
Is there an answer to this question: What was the British Indian Army mostly composed of?

Answer: Indian sepoys


Problem: Spanish language in the United States:

After the incorporation of these states to the United States in the first half of the 19th century, the Spanish language was later reinforced in the country by the acquisition of Puerto Rico in 1898. Later waves of emigration from Mexico, Cuba, El Salvador and elsewhere in Hispanic America to the United States beginning in the second half of the 19th century to the present-day have strengthened the role of the Spanish language in the country. Today, Hispanics are one of the fastest growing demographics in the United States, thus increasing the use and importance of American Spanish in the United States.

Which countries came in major emigrations to the US?
