Final answer:
The 14th Amendment guarantees the right to equal protection under both state and federal law for United States citizens.
Step-by-step explanation:
The 14th Amendment guarantees the right to equal protection under both state and federal law for United States citizens that other countries might deny. This means that individuals are protected from discrimination by the government based on factors such as race, gender, or religion. For example, if a state passed a law that discriminated against a particular racial or religious group, it would be considered unconstitutional under the 14th Amendment.
