Answer:
A. How is the European Union helping end antiziganism?
Step-by-step explanation:
The article about the Romani ethnic group is most likely followed by how the European Union is helping reduce antiziganism. The reason is that the article ends mentioning that the European Union has improved the "rights and privileges" of Romani people, who had always been persecuted for the common belief that their members are thieves and witches. Consequently, it would be interesting to know what measures the European Union has implemented to fight against with Romani discrimination and make their lives better.
The rest of the options are incorrect because they do not refer to the the main point of the article, which deals with the struggle the Romani people have suffered throughout history.
