Q: Answer the question from the given passage. Your answer should be directly extracted from the passage, and it should be a single entity, name, or number, not a sentence.
Passage: Islamist movements such as the Muslim Brotherhood, 'are well known for providing shelters, educational assistance, free or low cost medical clinics, housing assistance to students from out of town, student advisory groups, facilitation of inexpensive mass marriage ceremonies to avoid prohibitively costly dowry demands, legal assistance, sports facilities, and women's groups.' All this compares very favourably against incompetent, inefficient, or neglectful governments whose commitment to social justice is limited to rhetoric. Question: Why has the Muslim Brotherhood facilitated inexpensive mass marriage ceremonies?
A:
avoid prohibitively costly dowry demands
