Carefully explain two reasons why domestic crises can become international crises

What will be an ideal response?

Some crises are contagious. Direct linkages between economies can sometimes spread a crisis that begins in one economy and turn it into an international crisis (example: 2007 subprime crisis). Sometimes, two or more countries face similar financial crises because they share
a common set of economic fundamentals (example: Great Depression). Because economies share the same fundamentals, they are affected similarly by shocks.
