The correct response is: The political changes in each of these countries varied, but all of them were impacted in ways that changed the political landscape on a large scale.
Here's an explanation:
In Great Britain, industrialization led to the rise of a new industrial middle class and labor movements, resulting in significant political reforms, such as the Reform Acts that expanded the right to vote.
In Japan, the Meiji Restoration transformed the political landscape as the country rapidly industrialized and adopted Western political systems, moving from feudalism toward a more modern state with centralized authority.
In Germany, industrialization played a critical role in unifying the German states under the Prussian leadership of Otto von Bismarck and contributed to the rise of socialist movements, impacting the political structure significantly.
Thus, while the specifics of the political changes varied in each country, the effects of industrialization indeed led to large-scale transformations in the political landscapes.
