The accompanying graph depicts the labor markets for sanitation workers and landscapers. Both occupations face 55- identical labor demand curves (Demand). However, labor 50-1 supply differs. Supply 1 represents the supply of labor of 45- Supply 1 sanitation workers, and Supply 2 represents the supply of labor for landscapers. Assume that the skills and education 40- necessary for each job are identical. 35- What is the difference in equilibrium wages between the two 30- Supply 2 Hourly wage occupations? 25- 20- 15- Demand $ 10- 5 - 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 What might explain the different equilibrium wages for Quantity of laborWhat might explain the different equilibrium wages for these occupations? O Sanitation workers earn a higher wage due to fewer years of education. O The supply of sanitation workers is lower due to the unpleasantness of the job, which results in a compensating differential. O The supply of sanitation workers is greater, which results in a lower equilibrium wage
