Answer:
Railroads offered advantages over canals for transportation of goods.
Explanation:
The use of canals did not die out since you can see that there are still canals, and the map does not point out otherwise. In the map, there are cities, such as Plymouth or Falmouth, that don't have access to railroads. The map doesn't offer the information of transportation in all of Europe, just England, which is why it can't be that answer.
