Read the paragraph and study the graph.

In the 1980s, teen drinking was on the rise. Nearly two-thirds of high school seniors regularly consumed alcohol. To limit teen access to alcohol, the Uniform Drinking Age Act was enacted in 1984. The law resulted in all states adopting a minimum legal drinking age (MLDA) of 21. The graph shows the changes in the percent of high school seniors who used alcohol in the years 1984 to 2020.

A graph titled Alcohol Use by High School Seniors shows the percentage who drank alcohol on the y-axis labelled from 0 to 70 with an increment of 10 units versus the year on the x-axis labelled from 1985 to 2022 with an increment of 5 years. A blue dotted line starting from 70 steadily decreases until it reaches near 2020 and then there is a slight increase after 2020.

Based on the graph, what can be concluded about the impact of the Uniform Drinking Age Act on alcohol use by high school seniors?

Alcohol use by high school seniors has continued to increase.
Alcohol use by high school seniors has decreased over time.
Alcohol use by high school seniors was not directly impacted by the law.

Alcohol use by high school seniors has decreased over time.

The graph shows a steady decline from about 70% in the mid-1980s to much lower levels by 2020 (with only a slight uptick after 2020), consistent with a downward trend following the 1984 law.
