Question

your company works with freelancers and other companies to complete construction projects. youve talked to as many people as you can to learn about their careers. you met a structural engineer who earns over $100,000 a year and an electrician who earns around $60,000.
whats most likely the main reason for this difference in salary?
being an engineer requires more education and handling of more complex systems.
being an electrician has more physical risks than being an engineer.
electricians get other financial benefits that make up for the salary difference.
engineers are typically better at negotiating their salary.

Explanation:

Engineers generally need higher - level education and deal with more complex systems, which often leads to higher pay. Physical risks don't necessarily correlate directly with salary in this case. There's no indication of other financial benefits for electricians, and there's no evidence that engineers are better negotiators.

Answer:

Being an engineer requires more education and handling of more complex systems.
