The olmec are considered the "mother culture" of mesoamerica. where are they located?

a. along the coast of the gulf of mexico
b. near the columbia river in washington
c. extending along the andes mountain range
d. in the desert west

The correct answer is A, along the coast of the Gulf of Mexico.

Although the Olmec culture had a diffusion that reached most of Mesoamerica, one of the regions where the clearest evidences of the presence of this culture have been found is the southern part of the Coastal Plain of the Gulf of Mexico, included between the Papaloapan and Grijalva rivers, which corresponds to the northern half of the Isthmus of Tehuantepec. Currently, this zone corresponds to the southeast of the state of Veracruz and the west of Tabasco. It is an area of a warm and very humid climate, weather conditions that probably also possessed in the pre-Columbian antiquity in that place.

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.
