The Indians of the western grasslands were different. They refused to give up their way of life. These plains Indians were always on the move, because they hunted buffalo -- the American bison. They followed great groups of the animals across the grassy plains. At that time, there were millions of these animals in the American west.
The Indians of the plains depended on the buffalo for almost everything they needed. Many of them were fierce fighters. The plains Indians did not want white men crossing their hunting lands.
"A day after Austria-Hungary declared war on Serbia, <u>Russia</u> ordered mobilization against Austria-Hungary." Therefore, option (b) is the correct answer.
<h3>Which country mobilized against Austria-Hungary?</h3>
The true sequence of events is that once Austria-Hungary declared war on Serbia, Russia mobilized its forces, which led Germany to declare a two-front war against Russia and France.
When Austria-Hungary declared war on Serbia, it also signaled the start of World War I (WWI), which was eventually recognized as one of the world's worst and most destructive incidents.
The ordering of the mobilization of its forces by communist Russia was the cause of this declaration of war, which accelerated the start of the war between Germany and nations like Russia and France.
Therefore, out of the other choice, option (b): "Russia," is the correct answer.
