Which office requires at least 30 years old and 9 years as a citizen?

• A. Representative
• B. Senator
• C. President
• D. Judge

Answer: (B)

The main idea being tested is the constitutional qualifications for U.S. Senate members. The Constitution sets that a senator must be at least 30 years old and have been a citizen for at least nine years (plus residency in the state they represent). This combination matches the Senate’s eligibility rules, which is why selecting the option describing those requirements is the best answer.

By contrast, a representative must be at least 25 years old and a citizen for seven years, the president must be at least 35 and a natural-born citizen, and federal judges have no explicit age requirement stated in the Constitution (they are appointed for life, with other qualifications handled through appointment and confirmation).
