Chapter 18: Explain how District 11's action is noteworthy and/or remarkable?

After an emotional goodbye to Rue, she leaves the clearing feeling full of hatred. As she is about to make camp in a tree, another sponsor gift comes down. In it, she finds a loaf of bread, the type of bread specifically grown in District 11. She realizes it is a gesture of appreciation from Rue's district, particularly poignant since gifts are extremely expensive and the district is poor.
