For 14/15 year olds, until what time can they work between June 1st and Labor Day, assuming school is not scheduled?

The correct answer, which indicates that 14- and 15-year-olds can work until 8:30 pm between June 1st and Labor Day when school is not in session, is based on labor regulations that specifically outline the working hours for minors.

During the summer months when school is out, there are more flexible guidelines allowing younger workers to earn money while still ensuring they have sufficient time for leisure and rest. The cut-off time of 8:30 pm is designed to balance these needs, providing a reasonable limit for working hours in the evening.

The other choices provide times that are either too early or too late, not in line with the regulations established for the working hours of minors. Therefore, 8:30 pm is the appropriate closing time for young workers in this age group to ensure they can work safely and effectively while enjoying their summer break.
