Context and question: Although the drafts of both the Maastricht treaty and the Treaty establishing a Constitution for Europe mentioned federalism, the representatives of the member countries (all of whom would have had to agree to use of the term) never formally adopted it. The strongest advocates of European federalism have been Germany, Italy, Belgium and Luxembourg while those historically most strongly opposed have been the United Kingdom, Denmark and France (with conservative presidents and governments). Since the presidency of François Mitterrand (1981-1995), the French authorities have adopted a much more pro-European Unification position, as they consider that a strong EU is presenting the best "insurance" against a unified Germany which might become too strong and thus a threat for its neighbours.
When did the English authorities adopt the pro-European Unification position?

Context and question: At extremely large airports, a circuit is in place but not usually used. Rather, aircraft (usually only commercial with long routes) request approach clearance while they are still hours away from the airport, often before they even take off from their departure point. Large airports have a frequency called Clearance Delivery which is used by departing aircraft specifically for this purpose. This then allows aircraft to take the most direct approach path to the runway and land without worrying about interference from other aircraft. While this system keeps the airspace free and is simpler for pilots, it requires detailed knowledge of how aircraft are planning to use the airport ahead of time and is therefore only possible with large commercial airliners on pre-scheduled flights. The system has recently become so advanced that controllers can predict whether an aircraft will be delayed on landing before it even takes off; that aircraft can then be delayed on the ground, rather than wasting expensive fuel waiting in the air.
What do aircraft use instead of requesting approach clearance at very large airports?
Answer: unanswerable
Context and question: Jeffries and Ryan argue that no-aid position drew support from a coalition of separationist opinion. Most important was "the pervasive secularism that came to dominate American public life," which sought to confine religion to a private sphere. Further, the ban against government aid to religious schools was supported before 1970 by most Protestants (and most Jews), who opposed aid to religious schools, which were mostly Catholic at the time. After 1980, however, anti-Catholic sentiment has diminished among mainline Protestants, and the crucial coalition of public secularists and Protestant churches has collapsed. While mainline Protestant denominations are more inclined towards strict separation of church and state, much evangelical opinion has now largely deserted that position. As a consequence, strict separationism is opposed today by members of many Protestant faiths, even perhaps eclipsing the opposition of Roman Catholics.[citation needed]
What position do Jeffries and Ryan argue was the reason for support from a coalition of separationists?
Answer:
no-aid
