Problem: Windows 8:

Three milestone releases of Windows 8 leaked to the general public. Milestone 1, Build 7850, was leaked on April 12, 2011. It was the first build where the text of a window was written centered instead of aligned to the left. It was also probably the first appearance of the Metro-style font, and its wallpaper had the text shhh... let's not leak our hard work. However, its detailed build number reveals that the build was created on September 22, 2010. The leaked copy edition was Enterprise edition. The OS still reads as "Windows 7". Milestone 2, Build 7955, was leaked on April 25, 2011. The traditional Blue Screen of Death (BSoD) was replaced by a new Black screen, although this was later scrapped. This build introduced a new ribbon in Windows Explorer. Build 7959, with minor changes but the first 64-bit version, was leaked on May 1, 2011. The "Windows 7" logo was temporarily replaced with text displaying "Microsoft Confidential". On June 17, 2011, build 7989 64-bit edition was leaked. It introduced a new boot screen featuring the same fish as the default Windows 7 Beta wallpaper, which was later scrapped, and the circling dots as featured in the final (although the final version comes with smaller circling dots throbber). It also had the text Welcome below them, although this was also scrapped.

When was Milestone 1 divulged?

Problem: This is fortunate, since antennas at lower frequencies which are not rather large (a good fraction of a wavelength in size) are inevitably inefficient (due to the small radiation resistance Rr of small antennas). Most AM broadcast radios (except for car radios) take advantage of this principle by including a small loop antenna for reception which has an extremely poor efficiency. Using such an inefficient antenna at this low frequency (5301650 kHz) thus has little effect on the receiver's net performance, but simply requires greater amplification by the receiver's electronics. Contrast this tiny component to the massive and very tall towers used at AM broadcast stations for transmitting at the very same frequency, where every percentage point of reduced antenna efficiency entails a substantial cost.
Small and minimal frequency antennas are know to be what?

Answer: inefficient

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Much of mandolin development revolved around the soundboard (the top). Pre-mandolin instruments were quiet instruments, strung with as many as six courses of gut strings, and were plucked with the fingers or with a quill. However, modern instruments are louderusing four courses of metal strings, which exert more pressure than the gut strings. The modern soundboard is designed to withstand the pressure of metal strings that would break earlier instruments. The soundboard comes in many shapesbut generally round or teardrop-shaped, sometimes with scrolls or other projections. There is usually one or more sound holes in the soundboard, either round, oval, or shaped like a calligraphic F (f-hole). A round or oval sound hole may be covered or bordered with decorative rosettes or purfling.
What are ancient mandolins' strings made of?
A: unanswerable

Context and question: Alexander faced pressure from his brother, Duke Constantine, to make peace with Napoleon. Given the victory he had just achieved, the French emperor offered the Russians relatively lenient termsdemanding that Russia join the Continental System, withdraw its forces from Wallachia and Moldavia, and hand over the Ionian Islands to France. By contrast, Napoleon dictated very harsh peace terms for Prussia, despite the ceaseless exhortations of Queen Louise. Wiping out half of Prussian territories from the map, Napoleon created a new kingdom of 1,100 square miles called Westphalia. He then appointed his young brother Jerome as the new monarch of this kingdom. Prussia's humiliating treatment at Tilsit caused a deep and bitter antagonism which festered as the Napoleonic era progressed. Moreover, Alexander's pretensions at friendship with Napoleon led the latter to seriously misjudge the true intentions of his Russian counterpart, who would violate numerous provisions of the treaty in the next few years. Despite these problems, the Treaties of Tilsit at last gave Napoleon a respite from war and allowed him to return to France, which he had not seen in over 300 days.
What was the name of the younger brother who Napoleon appointed as the ruler of Westphalia?
Answer: Jerome

Question: In 1900, after Galveston was struck by a devastating hurricane, efforts to make Houston into a viable deep-water port were accelerated. The following year, oil discovered at the Spindletop oil field near Beaumont prompted the development of the Texas petroleum industry. In 1902, President Theodore Roosevelt approved a $1 million improvement project for the Houston Ship Channel. By 1910 the city's population had reached 78,800, almost doubling from a decade before. African-Americans formed a large part of the city's population, numbering 23,929 people, or nearly one-third of the residents.
Is there an answer to this question: Where was oil found that promoted the development of the oil industry in Houston?

Answer: Spindletop

Question: After Kerry's 1972 defeat, he and his wife bought a house in Belvidere, Lowell, entering a decade which his brother Cameron later called "the years in exile". He spent some time working as a fundraiser for the Cooperative for Assistance and Relief Everywhere (CARE), an international humanitarian organization. In September 1973, he entered Boston College Law School. While studying, Kerry worked as a talk radio host on WBZ and, in July 1974, was named executive director of Mass Action, a Massachusetts advocacy association.
Is there an answer to this question: Where did Kerry move after the 1972 election?

Answer:
Belvidere, Lowell
