I want to know the answer to the following question:
How old must a citizen of the Marshall Islands be to vote?
All the background I'm provided with is that "Elections are held every four years in universal suffrage (for all citizens above 18), with each of the twenty-four constituencies (see below) electing one or more representatives (senators) to the lower house of RMI's unicameral legislature, the Nitijela.". Is that enough to answer the question?
Answer: yes
