I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Many Pygmies belong from birth to Bantus in a relationship many refer to as slavery. The Congolese Human Rights Observatory says that the Pygmies are treated as property the same way "pets" are. On December 30, 2010, the Congolese parliament adopted a law for the promotion and protection of the rights of indigenous peoples. This law is the first of its kind in Africa, and its adoption is a historic development for indigenous peoples on the continent."?
What unique distinction does the Congolese law have?
