Its not 1 because Pilgrams were Christians while Puritans were Catholic.
Its not 2. Because of prior research.
Its not 3, because of logic.
Its not 4 because of the distance of where they lived.
So my logical guess is NUMBER 5.
In my opinion, the greatest accomplishment that the Roman civilization did was conquering land. The Roman's were very skilled when it comes to getting more land for their empire, and that's what they did. Because of how successful and powerful their military was, they conquered land that was already owned by other empire's. The Roman's conquered land from empire's like he Celtic tribes, Carthage, the Hellenistic Empires, and many more. They conquered a large amount of Europe, North Africa, and Western Asia. This makes it a very big accomplishment because no other Empire had the manpower that the Roman's had, and because of Rome's manpower, they were bound to conquer a lot of Europe and other land. Them expanding their empire allowed them to control most of Europe and other places.
Back then when slavery was a thing, there were abolitionists- to abolish is to end or stop- abolitionists for slavery would of helped slaves escape and they would of voted against slavery.
