Which conclusion is supported by the timeline? after viracocha died, the inca empire declined. the expansion of the aztec empire caused the inca empire to decline. the expansion of the inca empire caused the aztec empire to decline. after pachacuti took over, the inca empire focused on building projects.

Assuming that this is referring to the same timeline that was posted before with this question, the correct response would be that "The expansion of the Aztec empire caused the Inca empire to decline," since the two have a small but significant "overlap". 

In my honest opinion , i’d say franklin d roosevelt was a president that impacted our nation , i say this because fdr is voted among top three best us presidents and he was the longest serving president by 3 terms , usually presidents only supposed to have two terms increments of 4 years , equivalent to 8 years total before election time. and he established the fdic , through the 1933 banking act and he established the us , social security system , during his presidency, and established a national minimum wage , through the fair labor standards act , fdr led the allied coalition to victory in wwii and he played a major role in the creation of the united nations.
