However, trying to help you we can comment on the following.
The generalization about the Roman Empire that can be made based on the information is the following: "Rome traded only within the Empire."
This is correct because the information of the chart includes different regions of the empire such as Egypt, Greece, Britain, and Carthage.
Among the most important goods traded in Rome throughout the empire were linen, tin, marble, oil, and other raw materials and natural resources.
The Roman Empire was so vast that it could trade only within its dominions and made great profits. That is the reason why the Roman Empire built good roads to connect many regions within the empire.
In the underground railroad, there were safe places that the slave hid and slept that were called "safe houses" or "stations". The slaves traveled in a couple set of routes with regular paths. The slaves hid and slept in stations during the day and then traveled at night, because the slaves owners were looking for them during the day, so the slaves would be safer if they hid and slept during the day.
Therefore the answer that you are looking for is,
All of the above.
