In the decision for dred scott vs.sanford, (1857) in which a slave petitioned for his freedom in a st. louis court, on the grounds that his owner had taken him into free territory, and thus he ought no longer be regarded as possessing "slave" status, but should be regarded as a free man, the court decided as follows (excerpt): "in the circuit courts of the united states, the record must show that the case is one in which by the constitution and laws of the united states, the court had jurisdiction--and if this does not appear, and the court gives judgment either for plaintiff or defendant, it is error, and the judgment must be reversed by this court--and the parties cannot by consent waive the objection to the jurisdiction of the circuit court. a free negro of the african race, whose ancestors were brought to this country and sold as slaves, is not a 'citizen' within the meaning of the constitution of the united states. when the constitution was adopted, they were not regarded in any of the states as members of the community which constituted the state, and were not numbered among its 'people or citizen.' consequently, the special rights and immunities guarantied to citizens do not apply to them. and not being "citizens" within the meaning of the constitution, they are not entitled to sue in that character in a court of the united states, and the circuit court has not jurisdiction in such a suit. the only two clauses in the constitution which point to this race, treat them as persons whom it was morally lawful to deal in as articles of property and to hold as slaves. since the adoption of the constitution of the united states, no state can by any subsequent law make a foreigner or any other description of persons citizens of the united states, nor entitle them to the rights and privileges secured to citizens by that instrument." why does the court say that the petitioning party in this case had no right to sue for his freedom? a) because he is too young b) because he is from a different state c) because he is "of the african race" with enslaved ancestors d) because he is, properly speaking, within his owner's jurisdiction

Plz me asap. upon arrival of european powers on american soil, a quick end came to many native populations. numbers were devastated the longer europeans were present. many empires such as the aztec and inca were taken by force. the natives’ weapons of arrows and rocks were no match for gunpowder, steel swords, and horses. yet even after hostile takeovers, the native americans continued to suffer in numerous ways. according to las casas, the harshness of the encomienda system took many native lives. examples of such harshness included beatings by colonists and exhaustion caused by never-ending labor. natives were forced into slave labor in order to process colonists’ crops such as sugar cane and tobacco. these crops were referred to as “cash crops”. cash crops are crops grown not for sustenance but because they are extremely profitable. the colonies would have natives tend to these crops and they would then be exported to other european nations for high prices in order to make manufactured or processed goods. native slaves were worked for long hours in extremely hot temperatures with very little food, water, or breaks. they suffered savage beatings for working too slow and some were killed for refusal to work due to their exhaustion. poor health is another struggle natives faced upon european colonization. many natives died from hunger once colonists started to take their land. colonists’ cattle trampled native crops such as corn and squash. but possibly the most devastating factor in declining native populations were the diseases brought by europeans and against which the native people had no immunity. these included smallpox, typhus, chicken pox, mumps, and measles. hundreds upon thousands of natives fell to such diseases. entire villages were wiped out in mere days of the first symptom. native cities throughout the americas became desolate from the fast spread of disease. native american empires such as the aztec and the inca fell to the spanish and portuguese in the 1500s. the aztec alone had between sixteen and eighteen million people under their rule before europeans landed on the continent. why were these empires unable to fight the inevitable take over of european powers? use evidence from the text to support your answer.
