What did japan gain from signing the tripartite act? a) japan would have the support of germany and italy if america ever attacked japan. b) with no interference from germany and italy, japan could attack the soviet union. c) japan had rights to the pacific territories conquered by italy and germany. d) japan could now depend on germany and italy for its oil and scrap metal needs.

yes.

explanation:

because it let the japanese know who had the upper hand in the war.

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.
