the most likely reason countries have become more connected is they often depend on each other for social…

Brief Explanations:

In the context of international relations and economic interdependence (which falls under the Social Science discipline, specifically related to aspects of globalization and economic interactions), countries' increasing connection is highly tied to economic exchanges. Raw materials and finished products are key elements in global trade. Social systems are more internal and less a driver of broad - based inter - country connection. Loans and bail - outs are more crisis - driven and not the fundamental, ongoing reason for connection. Leadership needs are not as universal a driver as economic trade (raw materials and finished products).

Answer:

depend on each other more for raw materials and finished products.
