In the instructions for Relative Distance, the text says the degree of separation between Tariq and Uma is 3 (Tariq → Helena → Isla → Uma). However, this should be Tariq -> Isla -> Uma for two degrees of separation. Tariq and Isla are both siblings so there’s no need to travel up to Helena and back down.
