Passage: The principal Treaties that form the European Union began with common rules for coal and steel, and then atomic energy, but more complete and formal institutions were established through the Treaty of Rome 1957 and the Maastricht Treaty 1992 (now: TFEU). Minor amendments were made during the 1960s and 1970s. Major amending treaties were signed to complete the development of a single, internal market in the Single European Act 1986, to further the development of a more social Europe in the Treaty of Amsterdam 1997, and to make minor amendments to the relative power of member states in the EU institutions in the Treaty of Nice 2001 and the Treaty of Lisbon 2007. Since its establishment, more member states have joined through a series of accession treaties, from the UK, Ireland, Denmark and Norway in 1972 (though Norway did not end up joining), Greece in 1979, Spain and Portugal 1985, Austria, Finland, Norway and Sweden in 1994 (though again Norway failed to join, because of lack of support in the referendum), the Czech Republic, Cyprus, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia and Slovenia in 2004, Romania and Bulgaria in 2007 and Croatia in 2013. Greenland signed a Treaty in 1985 giving it a special status. Question: In what years did Spain and Portugal join the European Union?

Ex Output:
1985

Passage: Orientalism, as theorized by Edward Said, refers to how the West developed an imaginative geography of the East. This imaginative geography relies on an essentializing discourse that represents neither the diversity nor the social reality of the East. Rather, by essentializing the East, this discourse uses the idea of place-based identities to create difference and distance between 'we' the West and 'them' the East, or 'here' in the West and 'there' in the East. This difference was particularly apparent in textual and visual works of early European studies of the Orient that positioned the East as irrational and backward in opposition to the rational and progressive West. Defining the East as a negative vision of itself, as its inferior, not only increased the West’s sense of self, but also was a way of ordering the East and making it known to the West so that it could be dominated and controlled. The discourse of Orientalism therefore served as an ideological justification of early Western imperialism, as it formed a body of knowledge and ideas that rationalized social, cultural, political, and economic control of other territories. Question: Orientalism refers to how the West developed a what of the East?

Ex Output:
imaginative geography
