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.
Answer: D. People in the North organize to stop the spread of slavery

The Northern states had acted to abolish slavery in their own states and were against the practice unlike in the South where slavery was considered a way of life. These two wanted to spread their doctrines to the western territories so as to gain more influence.
This is why people in the North organized to stop the spread of slavery when the South wanted to spread it to the west leading to a very politically divided nation that would eventually go to war.
