Final answer:
The given statement is false because the 'Safe Roads Act of 1983' did not raise the national legal drinking age; it was the National Minimum Drinking Age Act of 1984 that mandated states to do so (option b).
Step-by-step explanation:
The statement that the "Safe Roads Act of 1983" raised the legal age for alcohal consumption" is false. The act referred to is actually the National Minimum Alcohal consumption Age Act of 1984. This legislation required all states to raise their legal alcohal consumption age to twenty-one or risk forfeiting a portion of their federal highway funds. This act was supported by an organization that pushed for higher legal alcohal consumption ages to prevent tragedies caused by drnk driving. By 1988, all states had complied with the regulations, setting the legal drinking age to twenty-one nationwide.
Hence, the answer is option b.
