Answer:
The Supreme Court ruled on March 8, 1857 that crossing state borders into a "free state" did not entitle slaves to their freedom.

Dred Scott was a slave during that time period who was brought into a "free state" by the family that owned him.

I think it should be The 3rd one. The south did farm tobacco, so I know it cant be that, and they did use slave labor more than the North, and the farm were called plantations. That leaves only the Dutch and German settlers.
 
        
             
        
        
        
It was 17% of slaves. Because during travel some died crossing the route. Like Antarctica. Since they didn't have much clothing they died from frost bite or hypothermia.  <span />
        
             
        
        
        
Justinian's Code, or the Corpus Juris Civilis, is a piece of the establishment of present day Western law. It fills in as the establishment for both the Napoleonic Code and the Germanistic code. These two codes of common law have impacted the improvement of law in numerous nations around the globe. 
In Justinian's time, the Corpus played out the significant capacity of bringing together legitimate guidelines over his realm. In the Renaissance, the Corpus began to impact Roman ordinance law and global law. 
At last, the Corpus is a basic hotspot for researchers. It gives a very composed and complete gathering of laws and lawful works from the most significant Classical creators. 
The initial segment of the Corpus was the Codex. This was a gathering of the considerable number of mandates issued by past rulers. Justinian's researchers needed to dispose of copy, out of date, or generally dangerous laws so as to make an assortment of laws that were reasonable for the Byzantine Empire as it existed in the sixth century CE. Later on, Justinian needed to issue his own laws, called the Novellae Constitutiones, to increase the Codes. The Novellae are viewed as the fourth and last piece of the Corpus. 
The other two pieces of the Corpus gave editorial and preparing in elucidation. The second part was known as the Digesta. The Digesta was a huge accumulation of determinations from the editorials of significant legal scholars. This shaped the reason for the elucidation of the laws. The third part was the Institutiones, which was a manual for utilizing the Codex and Digesta.
