What does it mean to say that service sector jobs are predominant in Europe’s mixed economies today?

That jobs where people work in factories predominate

That jobs where people do something for others predominate

That jobs in government predominate

That jobs in the service sector, which involve providing services rather than producing goods, are the most common in Europe's mixed economies today.

The correct answer is:

That jobs where people do something for others predominate.

In Europe's mixed economies, the service sector jobs are predominant. This means that there is a high concentration of occupations where people provide services to others, such as healthcare, education, retail, tourism, hospitality, finance, and professional services. These jobs involve delivering intangible value or performing tasks that cater to the needs and wants of individuals or businesses.
