Answer: Models are limited by the science—the more that was discovered, the better the model could be made.
Explanation:
At some point in history the well known early civilisations all thought that the Earth was flat. This includes Greece, India, Israel and even China with China only ceasing to believe such as recently as the 17th century. This is because that was what the science of the time led them to believe and so they made models of the Earth based on what they thought was true.
As time went by however and evidence was discovered by scientists and philosophers such as Aristotle that the world was round, the models began to change to depict a Spherical Earth.
This proves that models are simply a reflection of the science of the time and the more things are discovered, the more the Science gets more accurate enough to make better models.
A naval blockade can be a highly effective war strategy because it prevents the enemy from being able to send products to allies and it also prevents them from receiving supplies. If a country depends on imports from other countries/regions in order to survive, blocking their access to these resources can have a devastating effect on the country being blocked from everyone else. A military cannot last without the necessary supplies.
