If this is helpful to answering the question the improvements were:

Explanation:

computers

heat resistant materials

breathing systems for fire fighters

food-growing technologies

I think its space exploration as these were better computers were needed to calculate trajectories and heat resistant materials were needed so astronauts didn't burn up on entry. Food growing tech would've been needed because they would need to grow food eventually in space, so all of their food didn't run out. Breathing systems for firefighters would've been for astronauts walking in space's atmosphere, or rather lack thereof. It makes sense but I don't know for a fact. Still I hope this helps :3

answer: this is because archeologists keep finding artefacts and ancient ruins dated more than 10000 to 15000 years, date around scientists said humans discovered language; which is at least mysterious as scientists always have said that is necessary to have a language to have architecture and some basic maths.

explanation: brainlest

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.
