Problem: Glass:

The observation that old windows are sometimes found to be thicker at the bottom than at the top is often offered as supporting evidence for the view that glass flows over a timescale of centuries, the assumption being that the glass has exhibited the liquid property of flowing from one shape to another. This assumption is incorrect, as once solidified, glass stops flowing. The reason for the observation is that in the past, when panes of glass were commonly made by glassblowers, the technique used was to spin molten glass so as to create a round, mostly flat and even plate (the crown glass process, described above). This plate was then cut to fit a window. The pieces were not absolutely flat; the edges of the disk became a different thickness as the glass spun. When installed in a window frame, the glass would be placed with the thicker side down both for the sake of stability and to prevent water accumulating in the lead cames at the bottom of the window. Occasionally such glass has been found installed with the thicker side at the top, left or right.

When does glass stop moving like the bottom of the window?

Problem: The Spanish ship San Pedro and two other vessels in an expedition commanded by Miguel López de Legazpi discovered an island on January 9, 1530, possibly Mejit, at 10°N, which they named "Los Barbudos". The Spaniards went ashore and traded with the local inhabitants. On January 10, the Spaniards sighted another island that they named "Placeres", perhaps Ailuk; ten leagues away, they sighted another island that they called "Pajares" (perhaps Jemo). On January 12, they sighted another island at 10°N that they called "Corrales" (possibly Wotho). On January 15, the Spaniards sighted another low island, perhaps Ujelang, at 10°N, where they described the people on "Barbudos". After that, ships including the San Jeronimo, Los Reyes and Todos los Santos also visited the islands in different years.
What is thought to be the modern name of the island Legazpi called Los Barbudos?

Iran's rich cultural legacy is reflected in part by its 19 UNESCO World Heritage Sites, the fourth-largest number in Asia and 12th-largest in the world.

Context and question: Pius XII delivered an address about Montini's appointment from his sick-bed over radio to those assembled in St. Peter's Basilica on 12 December 1954. Both Montini and the pope had tears in their eyes when Montini parted for his dioceses with 1,000 churches, 2,500 priests and 3,500,000 souls. On 5 January 1955, Montini formally took possession of his Cathedral of Milan. Montini, after a period of preparation, liked his new tasks as archbishop, connecting to all groups of faithful in Milan. He enjoyed meetings with intellectuals, artists and writers.
In what year did Pius XII deliver a radio address announcing Montini's papal appointment?
Answer: 1954


Question: In the original city plan, the interstate buses should also stop at the Central Station. Because of the growth of Brasília (and corresponding growth in the bus fleet), today the interstate buses leave from the older interstate station (called Rodoferroviária), located at the western end of the Eixo Monumental. The Central Bus Station also contains a main metro station. A new bus station was opened in July 2010. It is on Saída Sul (South Exit) near Parkshopping Mall and with its metro station, and it's also an inter-state bus station, used only to leave the Federal District.
Is there an answer to this question: Because of the location of the Parkshopping Mall, where do buses leave from today?

Answer: unanswerable


QUES: 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.

How long had Richard Gephart served in house prior to being elected to minority leader?
What is the answer?
ANS:
20 years
