ANSWER: 2,3
Explanation:
UN inspectors to monitor its military sites, but their access will not be automatic and requests for access can be challenged by Iran. The deal reduces the number of Iranian centrifuges by two-thirds. It places bans on enrichment at key facilities, and limits uranium research and development to the Natanz facility. The deal caps uranium enrichment at 3.67 percent and limits the stockpile to 300 kg, all for 15 years. Iran will be required to ship spent fuel out of the country forever, as well as allow inspectors from the IAEA inspectors certain access in perpetuity. Heightened inspections, including tracking uranium mining and monitoring the production and storage of centrifuges, will last for up to 20 years.
