Reactivity series — practice question

The outcomes of two experiments are listed. 1. Cobalt displaces manganese from an aqueous solution of a manganese salt. 2. Manganese displaces silver from an aqueous solution of a silver salt. Three further experiments are then done: 3. Cobalt is added to an aqueous solution of a silver salt. 4. Manganese is added to an aqueous solution of a cobalt salt. 5. Silver is added to an aqueous solution of a cobalt salt. In which experiments does a reaction take place?
