Document 5: Source: http://www.authentichistory.com/1914-1920/1-overview/1 "One of the main causes of the First World War was imperialism: an unequal relationship, often in the form of an empire, forced on other countries and peoples, resulting in domination and subordination of economics, culture, and territory. Historians disagree on whether the primary impetus for imperialism was cultural or economic, but whatever the reason, Europeans in the late 19 th century increasingly chose to safeguard their access to markets, raw materials, and returns on their investments by seizing outright political and military control of the undeveloped world. Between the 1850 s and 1911, all of Africa was colonized except for Liberia and Ethiopia. The British, who had imposed direct rule on India in 1858, occupied Egypt in 1882 , probably a strategic necessity to protect their Indian interests. The French, who had begun missionary work in Indochina in the 17th century, finished theia conquests of the region in 1887, and in 1893 they added to it neighboring Laos and a small sliver of China. After 1897 Europeans hegan staking out "spheres of influence* in China, and the Dutch gradually expanded their old Company holdings to include all of modern day Indonesia in 1911, Italy conquered Libya from the Ottoman Empire, providing glory and the opportunity to relieve the population pressures in the south. In the East, Russia completed the Trans-Siberian Railroad (1891-1903) and established itself as a major Pacific power. Only Japan managed t contain European aggression by adopting European industrial techniques. Trade "capitulations" imposed on her in 1858 were successfully revoked in 1894, and by 1905 Japan had won successive wars with China and Russia. Germany, a late arrival at the imperialism game, achieved only a limited empiri in East and southwest Africa, and on the coast of China. Athough Germany successfully established colonies in the Pacific Southwest (most notably in the Solomon, Marshall, and Caroline Islands), Kaiser Withelm's interest in the Philippines had been dashed by United States acquisition of the archipelago in 1898, and German interests in the Western Hemisphere was stymied by President Theodore Roosevelt's diplomatic skill over the crisis in Venezuela in 1902, and by his subsequent corollary to the Monroe Doctrine in 1904. By 1914 the net result of imperialism was a world in which the Western powers had established themselves competitively on every continent. Britain had an empire 140 times its own size; Belgium, an empire 80 times its size; Holland, 60 times; and France, 20 times" Question: According to the passage, why did Britain occupy Egypt? a As a return on investments b To build a railioad across Africa c To get gold found near the Nile River d To protect their Indian interests
