Which statement regarding apprenticeships is true?

The statement that apprentices complete a combination of work and classroom hours is true because apprenticeships are structured to provide both practical, hands-on experience in a workplace setting and theoretical knowledge through classroom instruction. This dual approach ensures that apprentices are not only trained on the job but also learn the underlying concepts and principles related to their field. This comprehensive training prepares them effectively for a specific trade or profession, making them more competent and skilled.

In contrast, the other statements do not accurately reflect the nature of apprenticeships. For instance, apprentices are typically not required to work alone; instead, they are often guided by experienced professionals. Additionally, apprenticeships are designed to integrate formal education with work experience rather than exclude it, providing a rounded training approach. Lastly, apprenticeships are not limited to specific states; they are available in various regions and industries, depending on local labor needs and regulations.
