Question

how might the mandate system have affected the balance of power in europe?
the balance of power in europe remained the same.
britain and france came to be ruled by defeated nations.
some european countries became more powerful.

Explanation:

The post-WWI mandate system gave Britain and France control over former German and Ottoman territories, expanding their colonial holdings, resources, and global influence. This shifted Europe's power balance by making these two nations (and other mandate holders) more powerful relative to defeated powers like Germany, which lost its overseas territories. The first option is incorrect because power dynamics clearly shifted, and the second is false as Britain and France were victorious, not ruled by defeated nations.

Answer:

Some European countries became more powerful.
