求救，Proof of affinity with research skills该怎么准备？？

对鹿特丹伊拉斯姆斯大学的Research in Public Administration & Organizational Science很感兴趣，虽然知道希望渺茫，还是想想试试...

申请材料里有这么一项，
Proof of affinity with research skills, such as:
quantification of research skills in preliminary training
specific assessment of parts of a programme in which research skills have been practised and applied
research report
前两个完全不知道该怎么准备...难道真要选第三种方式，准备一份英文的研究报告么...完全没有头绪....

求指教，谢谢各位亲

求问...
