What happened at the Punggye-ri nuclear test site in 2018?

• A. The tunnels were destroyed in 2018.
• B. The site was expanded for more tests.
• C. The site was converted into a museum.
• D. The tunnels were destroyed in 2018 but later restored by 2022.

Answer: (D)

This item centers on the sequence of events at the Punggye-ri site in 2018 and what followed. In 2018, North Korea publicly announced the closure of Punggye-ri and staged a dismantling of tunnels, presenting it as a destruction of the test capability. By 2022, various assessments and imagery suggested that some tunnels could have been restored or prepared for re-entry, implying a potential revival of activity at the site. Putting these together, the description that tunnels were destroyed in 2018 but later restored by 2022 best captures what happened. There’s no evidence of the site being expanded for more tests or turned into a museum.
