The answer is A, the national and state governments share power.
Emperor Meiji finally achieved to get over the ancient and previous traditions of Shogun Lords, which lasted almost 800 years. With, the Meiji restoration, the country formerly established relations with powers in Europe, the United States, and other parts of the world. This became key "in putting Japan into the scene", in the international community. The ancient practices were not fostered anymore (based on Cultural and social distinctions ). It can be said that the nation had formerly consisted of huge differences to be considered relating what people have as an office, the status they served, etc.
So Japan finally entered the modern world, after a long series of wars that were targeted to maintaining the cultural unity and a policy of isolationism that also resulted in upgrading and incorporating changes in Japan foreign policy and structure of the military.
<span>The Mexican-American War (1846-1848) marked the first U.S. armed conflict chiefly fought on foreign soil. It pitted a politically divided and militarily unprepared Mexico against the expansionist-minded administration of U.S. President James K. Polk, who believed the United States had a “manifest destiny” to spread across the continent to the Pacific Ocean. A border skirmish along the Rio Grande started off the fighting and was followed by a series of U.S. victories. When the dust cleared, Mexico had lost about one-third of its territory, including nearly all of present-day California, Utah, Nevada, Arizona and New Mexico.</span>
