The correct answers are A. People without a high school degree tend to earn less than people with a high school degree. D. People with doctoral or professional degrees earn more, on average, than people with other degrees.
Explanation:
The graph shows the average wage for people with different degrees or levels of education from individuals with some but not complete high school education to individuals with doctoral or professional degrees.
Two of the factors this graph shows is that having a high school degree is associated with higher wages than people without it (option A) and that the highest degrees are associated to doctoral and professional levels (option D). The first factor is proved in the graph because people without a school degree earn in average less than $40.000, while people with this degree can earn $40.000. On the other hand, the second conclusion is shown in the graph because people with a professional or doctoral degree earn almost $120.000, which is higher than the wage earn by people with any other degree.
