Minors under the age of 18 cannot perform which of the following tasks unless defined as an apprentice?

Minors under the age of 18 are subject to specific labor laws and regulations that restrict their participation in certain hazardous occupations to ensure their safety and well-being. When it comes to roofing work, operating a power-driven circular saw, and performing excavating jobs, these tasks are generally classified as hazardous labor due to the risks involved such as falls, injuries from heavy equipment, and exposure to dangerous environments.

The designation of an apprentice can modify these restrictions. Apprenticeship programs are structured training programs that provide minors with the necessary skills and knowledge under the supervision of experienced professionals. Being defined as an apprentice allows minors to take part in these activities safely and legally while they are receiving formal training.

Given that all the tasks mentioned—roofing work, operating a power-driven circular saw, and doing excavating jobs—fall under hazardous work as regulated by labor laws, it is accurate that minors cannot perform these tasks unless they are defined as apprentices. Thus, the correct choice is that all of these tasks are prohibited for minors under the age of 18 unless they are part of an apprenticeship program.
