Paraphrasing.

Direct Quote: "The war in Darfur has led to what the U.N. has called the 'world's worst humaintarion crisis.' Over the past year, the conflict has spread into Chad, and hundreds of thousounds of Chadians have become refugees in their own country" (Polgreen, 19).

Paraphrase: The Darfur conflict has become an issue that is extremely problematic to not only Darfur, itself, but the world. It is spreading and causing people in other countries to become trapped in a war that is not their own (Polgreen, 19).
