What is the main problem of weavers?  
1) Lack of knowledge                            2) Lack of unity among weavers
3) Less payment to weavers                4) Lack of money.

Solution:

The option "Less payment to weavers" is a common challenge faced by weavers around the world. Weavers often earn low wages for their work, which can make it difficult for them to support themselves and their families. This is especially true in regions where the cost of living is high and there is little demand for handcrafted goods.
