What statements accurately describes the soviet economy under Khrushchev and Brezhnev?

Under Khrushchev, the Soviet economy experienced attempts at de-Stalinization and reforms aimed at increasing agricultural output, such as the Virgin Lands Campaign, but faced challenges like poor planning and inefficiencies. Brezhnev's era saw a return to a more conservative economic approach, marked by stagnation, with an emphasis on heavy industry and military production, resulting in a lack of innovation and declining agricultural productivity. Both leaders struggled with systemic inefficiencies and a centrally planned economy that ultimately hindered growth and adaptability.
