The first revolution toppled tsar rule and put a provisional government had little support,
This situation make it possible for the Bolsheviks second revolution to bring down the government. When the civil war was over, the Bolsheviks now replaced the tsar and hold the majority of control in the government. They later on replaced the officials that ruled under the tsar with their own, and implemented communist principle to Russian economy.
The correct answer is - Large numbers of migratory birds;
The number of the migratory birds has always been pretty high and it hadn't resulted in the drying up of the Ogallala Aquifer, not to mention that those birds can not even reach that water because it is underground. Also, the number of the migratory birds have been steadily lowering, so even if they were using that water for drinking, it wouldn't have caused the drying out.
The Ogallala Aquifer has started to dry out because of numerous reasons, with the usage of its water for irrigation being the prime reason. The droughts have become longer, and the temperatures little higher, while the rainfall slightly smaller, so all of that affected the reserves of water in the aquifer negatively.
Also known as the "Father of History". While many men are credited with "shaping" the story, one can be said to have "created" it. Herodotus developed the means by which we in the Western world can know and evaluate history and its most important moments. Born in Halicarnassus, Asia Minor, he played an important role in the revolution against tyrant Lydames. He later moved to Athens, where he began to systematically write down the history of his own time - particularly the wars between Greece and Persia - and the facts that preceded it. Although previous events had already been recorded, Herodotus is considered the "Father of History" because he was the first man to attempt an orderly and objective study of the interrelationships between historical events. Herodotus traveled to Egypt and traveled the Mediterranean, studying the cultures of these regions and recording the facts as faithfully as possible for the time. In theorizing about history, he applied the traditional Greek idea of moderation, or middle ground, that equilibrium is desirable, and excess and imbalance are the recipe for disaster. Because of this theory, the arrogant Xerxes I was inevitably doomed to defeat.
