Problem: United States dollar:

Today, USD notes are made from cotton fiber paper, unlike most common paper, which is made of wood fiber. U.S. coins are produced by the United States Mint. U.S. dollar banknotes are printed by the Bureau of Engraving and Printing and, since 1914, have been issued by the Federal Reserve. The "large-sized notes" issued before 1928 measured 7.42 inches (188 mm) by 3.125 inches (79.4 mm); small-sized notes, introduced that year, measure 6.14 inches (156 mm) by 2.61 inches (66 mm) by 0.0043 inches (0.11 mm). When the current, smaller sized U.S. currency was introduced it was referred to as Philippine-sized currency because the Philippines had previously adopted the same size for its legal currency.

What is most common paper made of?

A: wood fiber

Problem: In 1949, the club unveiled a modernised crest featuring the same style of cannon below the club's name, set in blackletter, and above the coat of arms of the Metropolitan Borough of Islington and a scroll inscribed with the club's newly adopted Latin motto, Victoria Concordia Crescit "victory comes from harmony", coined by the club's programme editor Harry Homer. For the first time, the crest was rendered in colour, which varied slightly over the crest's lifespan, finally becoming red, gold and green. Because of the numerous revisions of the crest, Arsenal were unable to copyright it. Although the club had managed to register the crest as a trademark, and had fought (and eventually won) a long legal battle with a local street trader who sold "unofficial" Arsenal merchandise, Arsenal eventually sought a more comprehensive legal protection. Therefore, in 2002 they introduced a new crest featuring more modern curved lines and a simplified style, which was copyrightable. The cannon once again faces east and the club's name is written in a sans-serif typeface above the cannon. Green was replaced by dark blue. The new crest was criticised by some supporters; the Arsenal Independent Supporters' Association claimed that the club had ignored much of Arsenal's history and tradition with such a radical modern design, and that fans had not been properly consulted on the issue.
Who did Arsenal supporters think should have been consulted before announcing the new crest?

According to Genius, the James Gleick-authored biography, Feynman tried LSD during his professorship at Caltech. Somewhat embarrassed by his actions, he largely sidestepped the issue when dictating his anecdotes; he mentions it in passing in the "O Americano, Outra Vez" section, while the "Altered States" chapter in Surely You're Joking, Mr. Feynman! describes only marijuana and ketamine experiences at John Lilly's famed sensory deprivation tanks, as a way of studying consciousness. Feynman gave up alcohol when he began to show vague, early signs of alcoholism, as he did not want to do anything that could damage his brainthe same reason given in "O Americano, Outra Vez" for his reluctance to experiment with LSD.
Why did Feynman give up alcohol?
A: he did not want to do anything that could damage his brain

Context and question: Scholars have characterized To Kill a Mockingbird as both a Southern Gothic and coming-of-age or Bildungsroman novel. The grotesque and near-supernatural qualities of Boo Radley and his house, and the element of racial injustice involving Tom Robinson contribute to the aura of the Gothic in the novel. Lee used the term "Gothic" to describe the architecture of Maycomb's courthouse and in regard to Dill's exaggeratedly morbid performances as Boo Radley. Outsiders are also an important element of Southern Gothic texts and Scout and Jem's questions about the hierarchy in the town cause scholars to compare the novel to Catcher in the Rye and Adventures of Huckleberry Finn. Despite challenging the town's systems, Scout reveres Atticus as an authority above all others, because he believes that following one's conscience is the highest priority, even when the result is social ostracism. However, scholars debate about the Southern Gothic classification, noting that Boo Radley is in fact human, protective, and benevolent. Furthermore, in addressing themes such as alcoholism, incest, rape, and racial violence, Lee wrote about her small town realistically rather than melodramatically. She portrays the problems of individual characters as universal underlying issues in every society.
Who does Scout revere above everyone else?
Answer: Atticus

Question: From 1938 until 1995, the U.S. Supreme Court did not invalidate any federal statute as exceeding Congress' power under the Commerce Clause. Most actions by the federal government can find some legal support among the express powers, such as the Commerce Clause, whose applicability has been narrowed by the Supreme Court in recent years. In 1995 the Supreme Court rejected the Gun-Free School Zones Act in the Lopez decision, and also rejected the civil remedy portion of the Violence Against Women Act of 1994 in the United States v. Morrison decision. Recently, the Commerce Clause was interpreted to include marijuana laws in the Gonzales v. Raich decision.
Is there an answer to this question: What did the court accept in 1995?

Answer: unanswerable

Problem: Database:

The conceptual view provides a level of indirection between internal and external. On one hand it provides a common view of the database, independent of different external view structures, and on the other hand it abstracts away details of how the data are stored or managed (internal level). In principle every level, and even every external view, can be presented by a different data model. In practice usually a given DBMS uses the same data model for both the external and the conceptual levels (e.g., relational model). The internal level, which is hidden inside the DBMS and depends on its implementation, requires a different level of detail and uses its own types of data structure types.

What view can't be presented by a different data model?

A:
unanswerable
