Explain each of the following terms: (a) Baton exchange zone (b) Steeple chase

(a) Baton exchange zone: A designated 30-metre section in relay races (such as the 4x100m relay) marked on the running track within which the baton must be successfully handed over from the incoming runner to the outgoing runner. The handover is only legal if the baton itself is within the boundary lines of this 30m zone at the moment of transfer. (b) Steeplechase: An Olympic middle-distance track event (most commonly 3000 metres) featuring fixed obstacles and a water jump. In a standard 3000m steeplechase, runners must clear a total of 28 hurdle barriers (91.4 cm high for men, 76.2 cm for women) and 7 water jumps, demanding exceptional endurance, jumping technique, and water-landing recovery.
