Context and question: Multi-layer printed circuit boards have trace layers inside the board. This is achieved by laminating a stack of materials in a press by applying pressure and heat for a period of time. This results in an inseparable one piece product. For example, a four-layer PCB can be fabricated by starting from a two-sided copper-clad laminate, etch the circuitry on both sides, then laminate to the top and bottom pre-preg and copper foil. It is then drilled, plated, and etched again to get traces on top and bottom layers.
Single-layer printed circuit boards have trace layers where?
Answer: unanswerable
Context and question: With Yoritomo firmly established, the bakufu system that would govern Japan for the next seven centuries was in place. He appointed military governors, or daimyos, to rule over the provinces, and stewards, or jito to supervise public and private estates. Yoritomo then turned his attention to the elimination of the powerful Fujiwara family, which sheltered his rebellious brother Yoshitsune. Three years later, he was appointed shogun in Kyoto. One year before his death in 1199, Yoritomo expelled the teenage emperor Go-Toba from the throne. Two of Go-Toba's sons succeeded him, but they would also be removed by Yoritomo's successors to the shogunate.
What was the name of the emperor that Yoritomo removed from the throne?
Answer: Go-Toba
Context and question: Between 1847 and 1850, when Blore was building the new east wing, the Brighton Pavilion was once again plundered of its fittings. As a result, many of the rooms in the new wing have a distinctly oriental atmosphere. The red and blue Chinese Luncheon Room is made up from parts of the Brighton Banqueting and Music Rooms with a large oriental chimney piece sculpted by Richard Westmacott. The Yellow Drawing Room has wallpaper supplied in 1817 for the Brighton Saloon, and a chimney piece which is a European vision of how the Chinese chimney piece may appear. It has nodding mandarins in niches and fearsome winged dragons, designed by Robert Jones.
What style are in none of the rooms in the new east wing?
Answer:
unanswerable
