The inevitable march to civil war and the combat in Madrid resulted in the removal of the capital of the Republic to Valencia. On 6 November 1936 the city became the capital of Republican Spain under the control of the prime minister Manuel Azana; the government moved to the Palau de Benicarlo, its ministries occupying various other buildings. The city was heavily bombarded by air and sea, necessitating the construction of over two hundred bomb shelters to protect the population. On 13 January 1937 the city was first shelled by a vessel of the Fascist Italian Navy, which was blockading the port by the order of Benito Mussolini. The bombardment intensified and inflicted massive destruction on several occasions; by the end of the war the city had survived 442 bombardments, leaving 2,831 dead and 847 wounded, although it is estimated that the death toll was higher, as the data given are those recognised by Francisco Franco's government. The Republican government passed to Juan Negrin on 17 May 1937 and on 31 October of that year moved to Barcelona. On 30 March 1939 Valencia surrendered and the Nationalist troops entered the city. The postwar years were a time of hardship for Valencians. During Franco's regime speaking or teaching Valencian was prohibited; in a significant reversal it is now compulsory for every schoolchild in Valencia.
How many bomb shelters were built?
over two hundred

As a result of continued warming, the polar ice caps melted and much of Gondwana became a desert. In Eastern Antarctica, seed ferns or pteridosperms became abundant and large amounts of sandstone and shale were laid down at this time. Synapsids, commonly known as "mammal-like reptiles", were common in Antarctica during the Early Triassic and included forms such as Lystrosaurus. The Antarctic Peninsula began to form during the Jurassic period (206146 Ma), and islands gradually rose out of the ocean. Ginkgo trees, conifers, bennettites, horsetails, ferns and cycads were plentiful during this period. In West Antarctica, coniferous forests dominated through the entire Cretaceous period (14666 Ma), though southern beech became more prominent towards the end of this period. Ammonites were common in the seas around Antarctica, and dinosaurs were also present, though only three Antarctic dinosaur genera (Cryolophosaurus and Glacialisaurus, from the Hanson Formation, and Antarctopelta) have been described to date. It was during this era that Gondwana began to break up.
What plants were abundant during this time?
pteridosperms

General Electric heavily contaminated the Hudson River with polychlorinated biphenyls (PCBs) between 1947-77. This pollution caused a range of harmful effects to wildlife and people who eat fish from the river or drink the water. In response to this contamination, activists protested in various ways. Musician Pete Seeger founded the Hudson River Sloop Clearwater and the Clearwater Festival to draw attention to the problem. The activism led to the site being designated by the EPA as one of the superfund sites requiring extensive cleanup. Other sources of pollution, including mercury contamination and sewage dumping, have also contributed to problems in the Hudson River watershed.
What does PCB stand for?
