¿Por qué para los europeos era tan importante el comercio con China y la India? *

El comercio con China e India era muy importante para los europeos durante la época antigua fundamentalmente por las características de los productos que allí se producían, los cuales eran eminentemente escasos en el continente europeo. Así, en estas regiones se producían productos como telas, especias, metales, etc., los cuales no eran comunes en Europa, lo cual acrecentaba enormemente su valor.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
