Article: Many applications of silicate glasses derive from their optical transparency, which gives rise to one of silicate glasses' primary uses as window panes. Glass will transmit, reflect and refract light; these qualities can be enhanced by cutting and polishing to make optical lenses, prisms, fine glassware, and optical fibers for high speed data transmission by light. Glass can be colored by adding metallic salts, and can also be painted and printed with vitreous enamels. These qualities have led to the extensive use of glass in the manufacture of art objects and in particular, stained glass windows. Although brittle, silicate glass is extremely durable, and many examples of glass fragments exist from early glass-making cultures. Because glass can be formed or molded into any shape, and also because it is a sterile product, it has been traditionally used for vessels: bowls, vases, bottles, jars and drinking glasses. In its most solid forms it has also been used for paperweights, marbles, and beads. When extruded as glass fiber and matted as glass wool in a way to trap air, it becomes a thermal insulating material, and when these glass fibers are embedded into an organic polymer plastic, they are a key structural reinforcement part of the composite material fiberglass. Some objects historically were so commonly made of silicate glass that they are simply called by the name of the material, such as drinking glasses and reading glasses.

Question: What quality of silicate glass allows it to be used for windows?
Ans: transparency

Here is a question about this article: In November, Seattle averages more rainfall than any other U.S. city of more than 250,000 people; it also ranks highly in winter precipitation. Conversely, the city receives some of the lowest precipitation amounts of any large city from June to September. Seattle is one of the five rainiest major U.S. cities as measured by the number of days with precipitation, and it receives some of the lowest amounts of annual sunshine among major cities in the lower 48 states, along with some cities in the Northeast, Ohio and Michigan. Thunderstorms are rare, as the city reports thunder on just seven days per year. By comparison, Fort Myers, Florida reports thunder on 93 days per year, Kansas City on 52, and New York City on 25.
What is the answer to this question: When does Seattle get it lowest levels of precipitation?
****
So... June to September

The problem: Answer a question about this article:
Only 14% of the population speaks Portuguese, established as the official language in the colonial period. Almost half the population (44%) speaks Crioulo, a Portuguese-based creole language, and the remainder speak a variety of native African languages. The main religions are African traditional religions and Islam; there is a Christian (mostly Roman Catholic) minority. The country's per-capita gross domestic product is one of the lowest in the world.
What percentage of the population speaks Crioulo?
****
The answer: 44%

Problem: Please answer a question about the following article about Bermuda:
Bermuda's national cricket team participated in the Cricket World Cup 2007 in the West Indies. Their most famous player is a 130 kilograms (290 lb) police officer named Dwayne Leverock. But India defeated Bermuda and set a record of 413 runs in a One-Day International (ODI). Bermuda were knocked out of the World Cup. Also very well-known is David Hemp, a former captain of Glamorgan in English first class cricket. The annual "Cup Match" cricket tournament between rival parishes St George's in the east and Somerset in the west is the occasion for a popular national holiday. This tournament began in 1872 when Captain Moresby of the Royal Navy introduced the game to Bermuda, holding a match at Somerset to mark forty years since the unjust thraldom of slavery. The East End versus West End rivalry resulted from the locations of the St. George's Garrison (the original army headquarters in Bermuda) on Barrack Hill, St. George's, and the Royal Naval Dockyard at Ireland Island. Moresby founded the Somerset Cricket Club which plays the St. George's Cricket Club in this game (the membership of both clubs has long been mostly civilian).
Why is there an East End/West End rivalry?
A: rivalry resulted from the locations

The modern pharmaceutical industry traces its roots to two sources. The first of these were local apothecaries that expanded from their traditional role distributing botanical drugs such as morphine and quinine to wholesale manufacture in the mid 1800s. Rational drug discovery from plants started particularly with the isolation of morphine, analgesic and sleep-inducing agent from opium, by the German apothecary assistant Friedrich Serturner, who named the compound after the Greek god of dreams, Morpheus. Multinational corporations including Merck, Hoffman-La Roche, Burroughs-Wellcome (now part of Glaxo Smith Kline), Abbott Laboratories, Eli Lilly and Upjohn (now part of Pfizer) began as local apothecary shops in the mid-1800s. By the late 1880s, German dye manufacturers had perfected the purification of individual organic compounds from coal tar and other mineral sources and had also established rudimentary methods in organic chemical synthesis. The development of synthetic chemical methods allowed scientists to systematically vary the structure of chemical substances, and growth in the emerging science of pharmacology expanded their ability to evaluate the biological effects of these structural changes.

Who came up with the name Morphine?
Answer: Friedrich Serturner

The group's second LP, Queen II, was released in 1974, and features rock photographer Mick Rock's iconic image of the band on the cover. This image would be used as the basis for the 1975 "Bohemian Rhapsody" music video production. The album reached number five on the British album chart and became the first Queen album to chart in the UK. The Freddie Mercury-written lead single "Seven Seas of Rhye" reached number ten in the UK, giving the band their first hit. The album is the first real testament to the band's distinctive layered sound, and features long complex instrumental passages, fantasy-themed lyrics, and musical virtuosity. Aside from its only single, the album also included the song "The March of the Black Queen", a six-minute epic which lacks a chorus. The Daily Vault described the number as "menacing". Critical reaction was mixed; the Winnipeg Free Press, while praising the band's debut album, described Queen II as a "over-produced monstrosity". Allmusic has described the album as a favourite among the band's hardcore fans, and it is the first of three Queen albums to feature in the book 1001 Albums You Must Hear Before You Die.
What was the name of Queen's second LP?
Queen II
