Answer:
1-John Deere’s plow
2-farmers no longer needed to harvest hand (McCormick’s reaper)
3-more cotton could be processed more quickly (Whitney’s cotton gin)
Explanation:
The limitations would be how much evidence was available and the truthfulness of the witnesses. The Code dealt with violations of the law. The law specified punishments based on who you were...slave or master, etc..
In the United States, depending on the context, the term “welfare” can be used to refer to means-tested cash benefits, especially the Aid to Families with Dependent Children (AFDC) program and its successor, the Temporary Assistance for Needy Families Block Grant, or it can be used to refer to all means-tested programs.
Precedent means "a decision that can be legally used due to the current situation"
For example, in the US constitution:
1) "The Ratification of the Conventions of 9 states, shall be sufficient for the Establishment of this Constitution between the states so ratifying the Same"
- It is already ratified, and so we don't really need it
2) "All debts contracted and Engagements entered into, before the adoption of this constitution, shall be as valid against the US under this Constitution, as under the Confederation"
-Again, it is already ratified, note that it says "before the adoption"
3) "No person held to Service or Labour in One state, under the laws thereof, escaping into another, shall, in consequence of any law or regulation therein, be discharged from such service or labour, but shall be delivered up on claim of the Party to whom such Service or Labour may be due".
- We really don't need this anymore, because we don't have slavery
hope this helps
