text: measures, some legislative, to guarantee to women the exercise and enjoyment of their rights and freedoms on an equal basis with men. In the USSR, both men and women enjoy the full range of socio-economic, political and personal rights and freedoms. Ensuring the equality and progress of women forms one of the most important aims of government. Economic and social development plans regularly include measures to improve women's life and working conditions, protect the mother and child and improve the social assistance extended to the family. The practical implementation of the principle of equal rights for men and women in the USSR is achieved through special measures provided for in the Constitution. These measures form a system of guarantees and privileges which allow work to be successfully combined with motherhood. The provisions are as follows; - a prohibition of discrimination in any form in the sphere of labour relations; a guarantee of equal rights to a free choice of profession or qualification, to promotion, to equal pay for equal work and to paid leave; - provision of equal access to education, professional training and improvement of skills; - state protection of women's labour and health, secured through the prohibition against using women for work involving hard or harmful conditions, the provision of free health care in specialized institutions within the national health system, the development of children's preschool facilities and other forms of public care and maintenance for children; - material and moral support for the mother and child, including maternity allowances to cover pregnancy and childbirth and the care of sick children, allowances for large families and single mothers, partly-paid leave for mothers with children up to the age of 12 months, privileged status in the sphere of social security, etc.; - legal protection of the rights of women against discrimination of any kind 
analysis: The text primarily focuses on the social and economic aspects of women's rights and equality in the USSR. It highlights the government's efforts to ensure equal opportunities, protection, and support for women in various aspects of life, including labor, education, healthcare, and family. The text does not mention economic development, natural resources, or international trade, which are key aspects of other categories. The emphasis on social security, healthcare, and education suggests that the category related to employment and human rights would be a good fit.
