The statement that most accurately describes the movement of ideas and goods during the Middle Ages is:
"The rivers of Europe allowed people to move easily and spread new ideas."
Rivers were important for trade and transportation, facilitating the movement of goods and the exchange of ideas throughout the continent. While the mountains did pose challenges, they were not the only factor affecting transportation. Additionally, while oceans and seas were important for travel to Asia, they were not the exclusive means. Lastly, European rivers generally flowed in multiple directions, contributing positively to trade and cultural exchange rather than limiting it.
