【单选题】

The reasons for the migration from rural to urban life were exploitation and lack of economic opportunity. The family members who would not inherit a share in the property were exploited by the laws of inheritance. The system was particularly hard on women, who usually did not share in the ownership of the farm and who rarely were paid for their labor. The workday for women was even more demanding than it was for men. Women were responsible for the kitchen garden and the small livestock as well as the care of the family. Unmarried women increasingly left the farm in search of economic opportunity in the factories that processed fish or farm products.

A．moved from farm to farm in search of work
