Document 10: Portugal: The Head of State of Portugal is the President of the Republic, elected to a five-year term by direct, universal suffrage. He or she has also supervision and reserve powers. These powers are often compared[by whom?] with the "moderator power" that was held by the King in the Portuguese Constitutional Monarchy.[citation needed] Presidential powers include the appointment of the Prime Minister and the other members of the Government (where the President takes into account the results of legislative elections); dismissing the Prime Minister; dissolving the Assembly of the Republic (to call early elections); vetoing legislation (which may be overridden by the Assembly with a supermajority); and declaring a state of war or siege.

Document 11: Gado-gado: "Gado-gado" is widely sold in almost every part of Indonesia, with each area having its own modifications. It is thought to have originally been a Sundanese dish, as it is most prevalent in Western parts of Java (which includes Jakarta, Banten, and West Java provinces). The Javanese have their own slightly similar version of a vegetables-in-peanut-sauce dish called "pecel" which is more prevalent in Central and East Java. "Gado-gado" is widely available from hawkers' carts, stalls ("warung") and restaurants and hotels in Indonesia; it is also served in Indonesian-style restaurants worldwide. Though it is customarily called a salad, the peanut sauce is a larger component of "gado-gado" than is usual for the dressings in Western-style salads; the vegetables should be well coated with it.
Document 12: Greece: According to the Constitution, executive power is exercised by the President of the Republic and the Government. From the Constitutional amendment of 1986 the President's duties were curtailed to a significant extent, and they are now largely ceremonial; most political power thus lies in the hands of the Prime Minister. The position of Prime Minister, Greece's head of government, belongs to the current leader of the political party that can obtain a vote of confidence by the Parliament. The President of the Republic formally appoints the Prime Minister and, on his recommendation, appoints and dismisses the other members of the Cabinet.
Document 13: Saltah: Saltah (Arabic: سلتة) is a Yemeni dish. It is widely eaten in northern parts of the country. It is mainly served for lunch.

Rice, potatoes, scrambled eggs, and vegetables are common additions to "saltah". It is eaten traditionally with Yemeni flat bread, which serves as a utensil to scoop up the food.
Document 14: Greek salad: Outside Greece, "Greek salad" may be a lettuce salad with Greek-inspired ingredients, even though the original dish is distinguished by the absence of lettuce. Meanwhile, the variant without lettuce may be called "horiatiki", "country salad", "peasant salad", or "village salad". Lettuce, tomatoes, feta (often served in multiple cube-shaped cuttings mixed with the vegetables), and olives are the most standard elements in an American-style Greek salad, but cucumbers, peperoncini (pickled hot peppers), bell peppers, onions, radishes, "dolmades", and anchovies/sardines are common. In Detroit, for example, Greek salad includes beets, and in the Tampa Bay Area, it often includes potato salad. Dressings containing various herbs and seasonings are frequently used in the U.S. This style of Greek salad is rarely encountered in Greece.
Document 15: President of South Africa: The President is elected by the National Assembly, the lower house of Parliament, and is usually the leader of the largest party, which has been the African National Congress since the first non-racial elections were held on 27 April 1994.
