Answer: Children in Industrial Plants.
Step-by-step explanation:
The photo shows an underage girl in an industrial plant. In this case, it is a plant for industrial processing and packaging of milk and dairy products. Photography is a practice that was evident in many plants worldwide at the beginning of the Industrial Revolution. Child labor was a regular occurrence at the time. This practice is forbidden in the modern age because, in civilized and democratic societies, minors' work in industrial plants is not allowed. Children are protected by various conventions enacted by the United Nations in the second half of the twentieth century.
