Answer:
The correct answer is A. According to the graph, voter turnout is especially low in midterm elections.
Explanation:
After several decades of increase, there has been a downward trend in the percentage of participation in the most consolidated democracies since the 1960s. In general, low participation may be due to disenchantment, apathy or satisfaction. It is often considered that low participation is not desirable and there has been a broad debate about the factors that affect participation and how to increase it. Despite the significant amount of studies on the subject, scholars are divided as to the reasons for the decline. Its cause has been attributed to a wide range of economic, demographic, cultural, technological, and institutional factors.
Specifically, midterm elections are considered as little relevant by the voters, so their participation is lower than in presidential elections in the vast majority of cases.
