<u>The correct answer is D. Gold was discovered in the Black Hills of South Dakota</u>. The federal government forgot the <em><u>Treaty of Laramie of 1868,</u></em> and on December 3, 1875, <em><u>ordered the Sioux to evacuate the territory and decreed a peremptory period (January 31, 1876</u></em>), after which those who refused to return to the reserves would be considered "hostile" with all the consequences that this term implied. The federal government decided to organize a military expedition to expel the now "hostiles" from the territory that had formally been recognized only eight years ago. In February 1876, preparations began. A long and extensive campaign was foreseen, given the difficulties of the climate and the immensity of the territory that had to be covered. In a first expedition, <em><u>the general George Crook left the first of March of 1876 towards the valleys of the Yellowstone and the Powder River, with the specific mission to destroy the village of the chief Sioux Caballo Loco</u></em>, after the Sioux Tribe declared war on the intruders and on the United States, as a consequence of the permanent invasions of <u>the sacred territory of the Black Hills because of the discovery of the existence of gold in 1871.</u>

the correct answer is D
it was related to the food supply
The early humans moved out Africa when the climatic condition in the region of East Africa Rift valley,where earliest stone tools were discovered became increasingly dry. Hunting as a source of food also became scarce as animals also spread out of the region. Subsequent strains in areas where they conquered led them to migrate further across the globe.
