explanation: "commemorate" describes a feeling of nostalgia for people or things, "forgetting" refers to not remembering, forgetting, and "commemoration" and "forgetting" have opposite meanings. "employ" includes "establish business". "propagating" and "guiding" have no obvious logical relationship. "dig" and "bury" mean the opposite. the need for "rescue" is when a "disaster" occurs.
