Answer:
Isolation.
Explanation:
One disadvantage of natural barriers is isolation. For example, if a group of people are living on an extremely small island in the middle of the Pacific Ocean, with lacking resources and a non-sturdy dinghy boat, the Pacific Ocean is serving as a natural barrier that isolates the group of people. Due to their lacking resources and nearly non-existent means of escape, this isolation is not at all beneficial.

the reason why is because of where the location of Venice and Florence is located near trade routes which makes it a very popular place to stop and trade.
Remember people are on the boats on a TRADE ROUTE and id they see people (or city's) they will most likely stop and TRADE with them.
