Martha is not too ambitious

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Martha unreels the tape measure as far as the root of a tree, and reads out a measurement of 7.11 metres. It is not revealed in the studio how inaccurate this measurement is, but she only receives 1 point, so it must have been bad.
