Problem: Please answer a question about the following article about Printed circuit board:
Semi-additive is the most common process: The unpatterned board has a thin layer of copper already on it. A reverse mask is then applied. (Unlike a subtractive process mask, this mask exposes those parts of the substrate that will eventually become the traces.) Additional copper is then plated onto the board in the unmasked areas; copper may be plated to any desired weight. Tin-lead or other surface platings are then applied. The mask is stripped away and a brief etching step removes the now-exposed bare original copper laminate from the board, isolating the individual traces. Some single-sided boards which have plated-through holes are made in this way. General Electric made consumer radio sets in the late 1960s using additive boards.
In the semi-additive process, what do the areas exposed by the mask become at the end?
A: traces
Problem: Please answer a question about the following article about Gamal Abdel Nasser:
Following the announcement of Nasser's death, Egypt and the Arab world were in a state of shock. Nasser's funeral procession through Cairo on 1 October was attended by at least five million mourners. The 10-kilometer (6.2 mi) procession to his burial site began at the old RCC headquarters with a flyover by MiG-21 jets. His flag-draped coffin was attached to a gun carriage pulled by six horses and led by a column of cavalrymen. All Arab heads of state attended, with the exception of Saudi King Faisal. King Hussein and Arafat cried openly, and Muammar Gaddafi of Libya fainted from emotional distress twice. A few major non-Arab dignitaries were present, including Soviet Premier Alexei Kosygin and French Prime Minister Jacques Chaban-Delmas.
What leader twice fainted during the funeral?
A: Muammar Gaddafi
Problem: Please answer a question about the following article about Elizabeth II:
In 2002, Elizabeth marked her Golden Jubilee. Her sister and mother died in February and March respectively, and the media speculated whether the Jubilee would be a success or a failure. She again undertook an extensive tour of her realms, which began in Jamaica in February, where she called the farewell banquet "memorable" after a power cut plunged the King's House, the official residence of the governor-general, into darkness. As in 1977, there were street parties and commemorative events, and monuments were named to honour the occasion. A million people attended each day of the three-day main Jubilee celebration in London, and the enthusiasm shown by the public for the Queen was greater than many journalists had expected.
How many people in London attended each day of the the three day event?
A: million
Problem: Please answer a question about the following article about Rule of law:
Most legal theorists believe that the rule of law has purely formal characteristics, meaning that the law must be publicly declared, with prospective application, and possess the characteristics of generality, equality, and certainty, but there are no requirements with regard to the content of the law. Others, including a few legal theorists, believe that the rule of law necessarily entails protection of individual rights. Within legal theory, these two approaches to the rule of law are seen as the two basic alternatives, respectively labelled the formal and substantive approaches. Still, there are other views as well. Some believe that democracy is part of the rule of law.
According to legal theorists, what characteristics must the rule of law have?
A:
generality, equality, and certainty
