B. The middle classes across Europe began to shrink as nations became wealthier.

Explanation:

This is the answer that best reflects the changes that started in Europe as a result of the expansion and global trade during the 15th and 18th centuries. Before the 15th century, the difference between wealthy people and the middle class was significant, but not massive. This is because the people did not have access to many luxury goods. However, with the rise of global trade, luxury goods became more common, and the wealthy began to accumulate more and more wealth. This led to a decline of the middle class and a rise in inequality.

b) trade is easy because of the direct line between their major ports. bilateral trade reached 89,6 thousand million.

the correct answer is individualism and exchange. at this stage, children begin to question the rules, because they can see that there is more than one side to them. different individuals have different viewpoints. they won't be able to reach this stage because of ignorance, a lack of ethics or personal biases. that is because people with that characteristiscs are not able to distinguish what is good or what is bad and they can't pursue their individual interests.
