Problem: Please answer a question about the following article about Detroit:
In November 1973, the city elected Coleman Young as its first black mayor. After taking office, Young emphasized increasing racial diversity in the police department. Young also worked to improve Detroit's transportation system, but tension between Young and his suburban counterparts over regional matters was problematic throughout his mayoral term. In 1976, the federal government offered $600 million for building a regional rapid transit system, under a single regional authority. But the inability of Detroit and its suburban neighbors to solve conflicts over transit planning resulted in the region losing the majority of funding for rapid transit. Following the failure to reach an agreement over the larger system, the City moved forward with construction of the elevated downtown circulator portion of the system, which became known as the Detroit People Mover.
How much did the federal government offer for a rapid transit system?
A: $600 million

Problem: Please answer a question about the following article about Child labour:
Similarly, in 1996, member countries of the European Union, per Directive 94/33/EC, agreed to a number of exceptions for young people in its child labour laws. Under these rules, children of various ages may work in cultural, artistic, sporting or advertising activities if authorised by the competent authority. Children above the age of 13 may perform light work for a limited number of hours per week in other economic activities as defined at the discretion of each country. Additionally, the European law exception allows children aged 14 years or over to work as part of a work/training scheme. The EU Directive clarified that these exceptions do not allow child labour where the children may experience harmful exposure to dangerous substances. Nonetheless, many children under the age of 13 do work, even in the most developed countries of the EU. For instance, a recent study showed over a third of Dutch twelve-year-old kids had a job, the most common being babysitting.
What age were children allowed to do light labour?
A:
13
