Question: An additional 4.6 billion tonnes of uranium are estimated to be in sea water (Japanese scientists in the 1980s showed that extraction of uranium from sea water using ion exchangers was technically feasible). There have been experiments to extract uranium from sea water, but the yield has been low due to the carbonate present in the water. In 2012, ORNL researchers announced the successful development of a new absorbent material dubbed HiCap which performs surface retention of solid or gas molecules, atoms or ions and also effectively removes toxic metals from water, according to results verified by researchers at Pacific Northwest National Laboratory.
Is there an answer to this question: About how many tonnes of uranium is theorized to be present in the sea?

Answer: 4.6 billion

Question: Yale seniors at graduation smash clay pipes underfoot to symbolize passage from their "bright college years," though in recent history the pipes have been replaced with "bubble pipes". ("Bright College Years," the University's alma mater, was penned in 1881 by Henry Durand, Class of 1881, to the tune of Die Wacht am Rhein.) Yale's student tour guides tell visitors that students consider it good luck to rub the toe of the statue of Theodore Dwight Woolsey on Old Campus. Actual students rarely do so. In the second half of the 20th century Bladderball, a campus-wide game played with a large inflatable ball, became a popular tradition but was banned by administration due to safety concerns. In spite of administration opposition, students revived the game in 2009, 2011, and 2014, but its future remains uncertain.
Is there an answer to this question: What do juniors crush to celebrate graduation?

Answer: unanswerable

Question: After back-to-back pennants in 1880 and 1881, Hulbert died, and Spalding, who had retired to start Spalding sporting goods, assumed ownership of the club. The White Stockings, with Anson acting as player/manager, captured their third consecutive pennant in 1882, and Anson established himself as the game's first true superstar. In 1885 and '86, after winning N.L. pennants, the White Stockings met the short-lived American Association champion in that era's version of a World Series. Both seasons resulted in match ups with the St. Louis Brown Stockings, with the clubs tying in 1885 and with St. Louis winning in 1886. This was the genesis of what would eventually become one of the greatest rivalries in sports. In all, the Anson-led Chicago Base Ball Club won six National League pennants between 1876 and 1886. As a result, Chicago's club nickname transitioned, and by 1890 they had become known as the Chicago Colts, or sometimes "Anson's Colts", referring to Cap's influence within the club. Anson was the first player in history credited with collecting 3,000 career hits. After a disappointing record of 59-73 and a 9th-place finish in 1897, Anson was released by the Cubs as both a player and manager. Due to Anson's absence from the club after 22 years, local newspaper reporters started to refer to the Cubs as the "Orphans".
Is there an answer to this question: While Anson led the Chicago cubs how many National League pennants did they win?

Answer: six

Question: Political parties, still called factions by some, especially those in the governmental apparatus, are lobbied vigorously by organizations, businesses and special interest groups such as trade unions. Money and gifts-in-kind to a party, or its leading members, may be offered as incentives. Such donations are the traditional source of funding for all right-of-centre cadre parties. Starting in the late 19th century these parties were opposed by the newly founded left-of-centre workers' parties. They started a new party type, the mass membership party, and a new source of political fundraising, membership dues.
Is there an answer to this question: Around which time was the mass membership party started?

Answer:
19th century
