What is one effect of the unequal distribution of resources? a. widely distributed resources come more valuable b. trade networks develop to exchange resources c. nations share resources with one another d. nations with few resources succeed without them

Best  B. Trade networks develop to exchange resources.

When one nation or region has resources that others do not, it can use those resources as a trade commodity to exchange with other nations.  For instance, areas that have rich oil resources will export oil to countries that don't have oil reserves as a natural resource.  In turn, those countries may have other commodities that they can exchange -- agricultural resources from countries with fertile agricultural land, for instance.

the main reason that the constitution did not proclaim all men to be free and equal is because of the issue of slavery.
