01 Which idea gained strength in Europe with the rise of the new middle class?
Answer and explanation
Correct answer: A. Nationalism and liberalism
Explanation: The governing concept is the role of the new middle class in spreading liberal nationalism. Educated professionals, merchants, and business groups supported individual freedom, equality before law, representative institutions, and national unity. These demands strengthened nationalism and liberalism, so option A is correct. Feudal privilege and absolute monarchy defended older hierarchies, while the slave trade was not the defining political idea associated with this class.
