Henriette does not factor in free will
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
It takes Henriette some time to spot the two metre tall letters A and B referred to in the task. She somehow manages to spot the B, up on the balcony, before the A she is standing right next to. She decides she is going to try to handicap Olli by blindfolding him, and making him drag two tyres around with him. However, she does not factor in his free will to remove the blindfold and drop the rope tied to the tyres, and he marches off towards the house unhindered, reaching the B on the balcony in just a minute. Henriette places last in the task.
