Exercise 1 solution

The ten: overhand (stop a rope end), figure-eight (bigger stopper), bowline (end loop), alpine butterfly (mid-rope loop), reef (bundles), sheet bend (join two ropes), clove hitch (quick fastening), round turn and two half hitches (secure, adjustable tie), taut-line hitch (adjustable loop), square lashing (bind poles).
A sensible swap: a sailor might swap the reef knot for a cleat hitch; a climber might add the figure-eight follow-through, learned in person.
Takeaway: knowing the job each knot does matters more than the name.
