Answer:
A law that treats 10-year-olds differently from 28-year-olds.
Explanation:
The rational basis test is a standard review procedure used by the court. Through this test, the court questions and evaluates a constitutional law or regulation and ensures that the law is rational or logical or not. A law that considers or treats a 10-year-olds differently from a 28-year-olds must provide a clear reason or rational that why is that so. Therefore, this law will be subject to the rational basis test.
