In Nuer Refugees in America, Shandy notes that the U.S. immigration service has settled the Nuer in about 30 different states because
 
  a. they could not find a single location for them all.
   b. they feel refugees adapt better if they are scattered in small groups around the
   country.
   c. they hoped to prevent the Nuer immigrants from finding each other and building
   communities here in the United States.
   d. their safety depends on hiding them among American families so that their political
   enemies cannot find them.
