Input: Read this: 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 in combination with glass fibers is used to make glass wool?

QUES: In 2006 Apple presented a special edition for iPod 5G of Irish rock band U2. Like its predecessor, this iPod has engraved the signatures of the four members of the band on its back, but this one was the first time the company changed the colour of the metal (not silver but black). This iPod was only available with 30GB of storage capacity. The special edition entitled purchasers to an exclusive video with 33 minutes of interviews and performance by U2, downloadable from the iTunes Store.

In what year was a special edition of the iPod produced?
What is the answer?
ANS: 2006


QUES: There is no single definition of an "aircraft carrier", and modern navies use several variants of the type. These variants are sometimes categorized as sub-types of aircraft carriers, and sometimes as distinct types of naval aviation-capable ships. Aircraft carriers may be classified according to the type of aircraft they carry and their operational assignments. Admiral Sir Mark Stanhope, former head of the Royal Navy, has said that "To put it simply, countries that aspire to strategic international influence have aircraft carriers".
How may aircraft be classified?

The majority of Sicilians preferred independence to the Savoia kingdom; in 1866, Palermo became the seat of a week-long popular rebellion, which was finally crushed after Martial law was declared. The Italian government blamed anarchists and the Church, specifically the Archbishop of Palermo, for the rebellion and began enacting anti-Sicilian and anti-clerical policies. A new cultural, economic and industrial growth was spurred by several families, like the Florio, the Ducrot, the Rutelli, the Sandron, the Whitaker, the Utveggio, and others. In the early twentieth century Palermo expanded outside the old city walls, mostly to the north along the new boulevards Via Roma, Via Dante, Via Notarbartolo, and Viale della Libertà. These roads would soon boast a huge number of villas in the Art Nouveau style. Many of these were designed by the famous architect Ernesto Basile. The Grand Hotel Villa Igiea, designed by Ernesto Basile for the Florio family, is a good example of Palermitan Art Nouveau. The huge Teatro Massimo was designed in the same period by Giovan Battista Filippo Basile, and built by the Rutelli & Machì building firm of the industrial and old Rutelli Italian family in Palermo, and was opened in 1897.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who prefered the Savoia kingdom to independence?
Ah, so.. unanswerable


Question: Like many older east coast cities after World War II, Atlantic City became plagued with poverty, crime, corruption, and general economic decline in the mid-to-late 20th century. The neighborhood known as the "Inlet" became particularly impoverished. The reasons for the resort's decline were multi-layered. First of all, the automobile became more readily available to many Americans after the war. Atlantic City had initially relied upon visitors coming by train and staying for a couple of weeks. The car allowed them to come and go as they pleased, and many people would spend only a few days, rather than weeks. Also, the advent of suburbia played a huge role. With many families moving to their own private houses, luxuries such as home air conditioning and swimming pools diminished their interest in flocking to the luxury beach resorts during the hot summer. But perhaps the biggest factor in the decline in Atlantic City's popularity came from cheap, fast jet service to other premier resorts, such as Miami Beach and the Bahamas.
Try to answer this question if possible: After the war, what form of transportation became more readily available to many Americans?
Answer: automobile


Problem: After the American Revolutionary War, Richmond emerged as an important industrial center. To facilitate the transfer of cargo from the flat-bottomed bateaux above the fall line to the ocean-faring ships below, George Washington helped design the James River and Kanawha Canal in the 18th century to bypass Richmond's rapids, with the intent of providing a water route across the Appalachians to the Kanawha River. The legacy of the canal boatmen is represented by the figure in the center of the city flag. As a result of this and ample access to hydropower due to the falls, Richmond became home to some of the largest manufacturing facilities in the country, including iron works and flour mills, the largest facilities of their kind in the South. The resistance to the slave trade was growing by the mid-nineteenth century; in one famous case in 1848, Henry "Box" Brown made history by having himself nailed into a small box and shipped from Richmond to abolitionists in Philadelphia, Pennsylvania, escaping slavery.
To where was the canal designed by Washington intended to ferry water?
---
Answer:
Kanawha River
