The supreme judicial power is vested in the Supreme Court or Riigikohus, with nineteen justices. The Chief Justice is appointed by the parliament for nine years on nomination by the president. The official Head of State is the President of Estonia, who gives assent to the laws passed by Riigikogu, also having the right of sending them back and proposing new laws.

PROBLEM: Passage: With the Conference of Berlin of 1884, Portuguese Africa territories had their borders formally established on request of Portugal in order to protect the centuries-long Portuguese interests in the continent from rivalries enticed by the Scramble for Africa. Portuguese Africa's cities and towns like Nova Lisboa, Sa da Bandeira, Silva Porto, Malanje, Tete, Vila Junqueiro, Vila Pery and Vila Cabral were founded or redeveloped inland during this period and beyond. New coastal towns like Beira, Mocamedes, Lobito, Joao Belo, Nacala and Porto Amelia were also founded. Even before the turn of the 20th century, railway tracks as the Benguela railway in Angola, and the Beira railway in Mozambique, started to be built to link coastal areas and selected inland regions. Question: During what period were the Portugese Africa's cities founded or redeveloped?

SOLUTION: Scramble for Africa

PROBLEM: Passage: The Somerset Levels (or Somerset Levels and Moors as they are less commonly but more correctly known) are a sparsely populated wetland area of central Somerset, between the Quantock and Mendip hills. They consist of marine clay levels along the coast, and the inland (often peat based) moors. The Levels are divided into two by the Polden Hills; land to the south is drained by the River Parrett while land to the north is drained by the River Axe and the River Brue. The total area of the Levels amounts to about 647.5 square kilometres (160,000 acres) and broadly corresponds to the administrative district of Sedgemoor but also includes the south west of Mendip district. Approximately 70% of the area is grassland and 30% is arable. Stretching about 32 kilometres (20 mi) inland, this expanse of flat land barely rises above sea level. Before it was drained, much of the land was under a shallow brackish sea in winter and was marsh land in summer. Drainage began with the Romans, and was restarted at various times: by the Anglo-Saxons; in the Middle Ages by the Glastonbury Abbey, from 14001770; and during the Second World War, with the construction of the Huntspill River. Pumping and management of water levels still continues. Question: what do the Somerset levels consist of

SOLUTION:
marine clay levels along the coast, and the inland (often peat based) moors
