Please answer the following question: Information: - The North African Campaign of the Second World War took place in North Africa from 10 June 1940 to 13 May 1943. It included campaigns fought in the Libyan and Egyptian deserts (Western Desert Campaign, also known as the Desert War) and in Morocco and Algeria (Operation Torch) and Tunisia (Tunisia Campaign). - French North Africa was a collection of territories in North Africa controlled by France and centering on French Algeria. At its height, it was a large part of the Maghreb. - A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is under threat from humans. Norman Myers wrote about the concept in two articles in The Environmentalist (1988), & 1990 revised after thorough analysis by Myers and others in Hotspots: Earths Biologically Richest and Most Endangered Terrestrial Ecoregions and a paper published in the journal "Nature" - Operation Torch (initially called Operation Gymnast) was the British-American invasion of French North Africa during the North African Campaign of the Second World War which started on 8 November 1942. - India, officially the Republic of India ("Bhrat Gaarjya"), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country (with over 1.2 billion people), and the most populous democracy in the world. It is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the northeast; and Myanmar (Burma) and Bangladesh to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia. Its capital is New Delhi; other metropolises include Mumbai, Kolkata, Chennai, Bangalore, Hyderabad and Ahmedabad. - The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by the English kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years War against the kingdom of France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is known as the Senior Service. - The Malagasy Republic was a state situated in Southeast Africa. It was established in 1958 as an autonomous republic within the newly created French Community and existed until the proclamation of the Democratic Republic of Madagascar in 1975. - The Royal Naval Commandos were a commando formation of the Royal Navy which served during the Second World War . The first units were raised in 1942 and by the end of the war , 22 company - sized units had been raised to carry out various tasks associated with establishing , maintaining and controlling beachheads during amphibious operations . Royal Naval Commando parties took part in all Allied amphibious landings from early 1942 to the end of the war , when they were disbanded . Operations included the landings at Diego Suarez on Madagascar , Operation Torch , Operation Neptune , the Screwdriver operations in Burma , Operation Market - Garden and the assault on Walcheren . - Madagascar, officially the Republic of Madagascar, and previously known as the Malagasy Republic, is an island country in the Indian Ocean, off the coast of Southeast Africa. The nation comprises the island of Madagascar (the fourth-largest island in the world), and numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian peninsula around 88million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of its wildlife is found nowhere else on Earth. The island's diverse ecosystems and unique wildlife are threatened by the encroachment of the rapidly growing human population and other environmental threats. - A beachhead is a temporary line created when a military unit reaches a landing beach by sea and begins to defend the area while other reinforcements help out until a unit large enough to begin advancing has arrived. The term is sometimes used interchangeably (both correctly and incorrectly) with "bridgehead" and "lodgement". Beachheads were very important in operations such as "Operation Neptune" during World War II, the Korean War (especially at Inchon), and the Vietnam War, among many other examples. - The Indian Ocean is the third largest of the world's oceanic divisions, covering (approximately 20% of the water on the Earth's surface). It is bounded by Asia on the north, on the west by Africa, on the east by Australia, and on the south by the Southern Ocean or, depending on definition, by Antarctica. It is named after the country of India. The Indian Ocean is known as "Ratnkara", ""the mine of gems"" in ancient Sanskrit literature, and as "Hind Mahsgar", ""the great Indian sea"", in Hindi. - In paleogeography, Gondwana, also Gondwanaland, is the name given to an ancient supercontinent. It is believed to have sutured between about 573 and 510million years ago(Mya), joining East Gondwana to West Gondwana. Gondwana formed prior to Pangaea, and later became part of it. - An island country is a country whose primary territory consists of one or more islands or parts of islands. As of 2011, 46 (approximately 24%) of the 193 UN member states are island countries. - The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union. - In geology, a supercontinent is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass. However, the definition of a supercontinent can be ambiguous. Many earth scientists, such as P.F. Hoffman (1999), use the term "supercontinent" to mean "a clustering of nearly all continents". This definition leaves room for interpretation when labeling a continental body and is easier to apply to Precambrian times. Using the first definition provided here, Gondwana (a.k.a. Gondwanaland) is not considered a supercontinent, because the landmasses of Baltica, Laurentia and Siberia also existed at the same time but physically separate from each other. The landmass of Pangaea is the collective name describing all of these continental masses when they were in proximity to one another. This would classify Pangaea as a supercontinent. According to the definition by Rogers and Santosh (2004), a supercontinent does not exist today. Supercontinents have assembled and dispersed multiple times in the geologic past (see table). The positions of continents have been accurately determined back to the early Jurassic. However, beyond , continental positions are much less certain.
