The correct answer to this open question is the following.
Three ways in which the government can ensure that the help it offers is received only by the people who are in need are the following.
1.- Clearly identify the people who are needing help. Who they are, where they are, and for what reasons are needing the government's help. Elaborate a list with names and address of these people.
2.- Determine the exact amount of help they need and the way it is going to be delivered to them. How much they need would be identified in the base of the necessities detected in step number one. If transportation would be supplied by a government office or the military, both need to have a good inventory of things to be supplied.
3.- Before delivering the goods, elaborate a receipt format for the people to sign it at the moment they are receiving the help. It must include, the date, the place, the number of goods received, an official ID. People must sign when receiving aid.
