Problem: Printed circuit board:

Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. Rub-on dry transfers of common component footprints increased efficiency. Traces were made with self-adhesive tape. Pre-printed non-reproducing grids on the mylar assisted in layout. To fabricate the board, the finished photomask was photolithographically reproduced onto a photoresist coating on the blank copper-clad boards.

Pin pads were laid out on the nylon and then what?

A: unanswerable


Problem: In Sri Lanka, the Supreme Court of Sri Lanka was created in 1972 after the adoption of a new Constitution. The Supreme Court is the highest and final superior court of record and is empowered to exercise its powers, subject to the provisions of the Constitution. The court rulings take precedence over all lower Courts. The Sri Lanka judicial system is complex blend of both common-law and civil-law. In some cases such as capital punishment, the decision may be passed on to the President of the Republic for clemency petitions. However, when there is 2/3 majority in the parliament in favour of president (as with present), the supreme court and its judges' powers become nullified as they could be fired from their positions according to the Constitution, if the president wants. Therefore, in such situations, Civil law empowerment vanishes.
What was adopted before 1972?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
As a schoolboy, Gaddafi adopted the ideologies of Arab nationalism and Arab socialism, influenced in particular by Nasserism, the thought of Egyptian revolutionary and president Gamal Abdel Nasser, whom Gaddafi adopted as his hero. During the early 1970s, Gaddafi formulated his own particular approach to Arab nationalism and socialism, known as Third International Theory, which has been described as a combination of "utopian socialism, Arab nationalism, and the Third World revolutionary theory that was in vogue at the time". He laid out the principles of this Theory in the three volumes of The Green Book, in which he sought to "explain the structure of the ideal society." His Arab nationalist views led him to believe that there needed to be unity across the Arab world, combining the Arab nation under a single nation-state. He described his approach to economics as "Islamic socialism", although biographers Blundy and Lycett noted that Gaddafi's socialism had a "curiously Marxist undertone", with political scientist Sami Hajjar arguing that Gaddafi's model of socialism offered a simplification of Karl Marx and Friedrich Engels' theories. Gaddafi saw his socialist Jamahiriyah as a model for the Arab, Islamic, and non-aligned worlds to follow.
What philosophy was named for Gamal Abdel Nasser?
A: Nasserism


Context and question: Aposematism, where organisms are brightly colored as a warning to predators, is the antithesis of camouflage. Some organisms pose a threat to their predators—for example they may be poisonous, or able to harm them physically. Aposematic coloring involves bright, easily recognizable and unique colors and patterns. For example, bright coloration in Variable Checkerspot butterflies leads to decreased predation attempts by avian predators. Upon being harmed (e.g., stung) by their prey, the appearance in such an organism will be remembered as something to avoid. While that particular prey organism may be killed, the coloring benefits the prey species as a whole.
What do predators use to warn their prey?
Answer: unanswerable


Question: A sequence of events, or series of events, is a sequence of items, facts, events, actions, changes, or procedural steps, arranged in time order (chronological order), often with causality relationships among the items. Because of causality, cause precedes effect, or cause and effect may appear together in a single item, but effect never precedes cause. A sequence of events can be presented in text, tables, charts, or timelines. The description of the items or events may include a timestamp. A sequence of events that includes the time along with place or location information to describe a sequential path may be referred to as a world line.
Is there an answer to this question: What never precedes cause because of timelines?

Answer: unanswerable


QUES: The army has relied heavily on tents to provide the various facilities needed while on deployment. The most common tent uses for the military are as temporary barracks (sleeping quarters), DFAC buildings (dining facilities), forward operating bases (FOBs), after action review (AAR), tactical operations center (TOC), morale, welfare, and recreation (MWR) facilities, and security checkpoints. Furthermore, most of these tents are set up and operated through the support of Natick Soldier Systems Center.

What does FOB stand for?
