One Argument That Often Is Given in Favor of Foreign

One argument that often is given in favor of foreign aid as an effective tool to help developing countries is that:

A) there is no evidence that aid money is ever diverted to other purposes.
B) aid money is likely to be used to provide extra benefits to government leaders.
C) corruption is a larger problem in high-income countries and so aid money is likely to be spent more efficiently in a developing country than in a high-income country.
D) problems are worse in developing countries and so aid dollars given to them address more critical issues than the dollars that are spent in a high-income country.
