PART A: according to the text, how does this affect Rohingya refugees' of hope

Incomplete question. I inferred you want a brief description of who this group of people are.

Explanation:

The Rohingya is an ethnic group that were found mainly in northern Myanmar. According to the UN they are experiencing a modern form of abuse and genocide by Myanmar's Buddhist population.

In fact they do have official national identify since they are not among the 135 officially recognized ethnic groups in Myanmar during it last census. This situation has made thousands become refugees (persons forced to leave their country).
