Final answer:
The statement about early alcohol use and later dependency is true, reflecting concerns addressed by laws such as the National Minimum Drinking Age Act of 1984.
Step-by-step explanation:
The statement that 47% of people who began drinking at or before the age of 14 became dependent on alcohol at some point in their life is true. Studies and historical data have indicated that early exposure to alcohol can lead to a higher risk of alcohol dependency later in life. This issue is intertwined with public health and the minimum drinking age laws, such as the National Minimum Drinking Age Act of 1984, which indirectly reflects on efforts to prevent early alcohol dependency by setting a legal threshold for alcohol consumption. Nearly 47% of people who began drinking at or before the age of 14 became dependent on alcohol at some point in their life.
