Input: Article: Despite wide use by politicians, judges and academics, the rule of law has been described as "an exceedingly elusive notion". Among modern legal theorists, one finds that at least two principal conceptions of the rule of law can be identified: a formalist or "thin" definition, and a substantive or "thick" definition; one occasionally encounters a third "functional" conception. Formalist definitions of the rule of law do not make a judgment about the "justness" of law itself, but define specific procedural attributes that a legal framework must have in order to be in compliance with the rule of law. Substantive conceptions of the rule of law go beyond this and include certain substantive rights that are said to be based on, or derived from, the rule of law.

Now answer this question: What is another word for a thin definition?

Output: formalist

Here is a question about this article: The Aeronautics Branch was renamed the Bureau of Air Commerce in 1934 to reflect its enhanced status within the Department. As commercial flying increased, the Bureau encouraged a group of airlines to establish the first three centers for providing air traffic control (ATC) along the airways. In 1936, the Bureau itself took over the centers and began to expand the ATC system. The pioneer air traffic controllers used maps, blackboards, and mental calculations to ensure the safe separation of aircraft traveling along designated routes between cities.
What is the answer to this question: When did the Buerau take over and begin to expant the ATC system?
****
So... 1936


The problem: Answer a question about this article:
The Quine-Duhem thesis argues that it's impossible to test a single hypothesis on its own, since each one comes as part of an environment of theories. Thus we can only say that the whole package of relevant theories has been collectively falsified, but cannot conclusively say which element of the package must be replaced. An example of this is given by the discovery of the planet Neptune: when the motion of Uranus was found not to match the predictions of Newton's laws, the theory "There are seven planets in the solar system" was rejected, and not Newton's laws themselves. Popper discussed this critique of naïve falsificationism in Chapters 3 and 4 of The Logic of Scientific Discovery. For Popper, theories are accepted or rejected via a sort of selection process. Theories that say more about the way things appear are to be preferred over those that do not; the more generally applicable a theory is, the greater its value. Thus Newton's laws, with their wide general application, are to be preferred over the much more specific "the solar system has seven planets".[dubious – discuss]
Which of Popper's works responds to critiques of naive falsificationism?
****
The answer: The Logic of Scientific Discovery


The problem: Answer a question about this article:
The first elevator shaft preceded the first elevator by four years. Construction for Peter Cooper's Cooper Union Foundation building in New York began in 1853. An elevator shaft was included in the design, because Cooper was confident that a safe passenger elevator would soon be invented. The shaft was cylindrical because Cooper thought it was the most efficient design. Later, Otis designed a special elevator for the building. Today the Otis Elevator Company, now a subsidiary of United Technologies Corporation, is the world's largest manufacturer of vertical transport systems.
Which was built first, the first elevator shaft or the first elevator?
****
The answer:
first elevator shaft
