not sure why I need to “provide definitions” of means, task, and attainment instead of illustrative examples?
also, can I draw your attention again to the passage that very explicitly says that (bottom of page 9, top of 10) that these dimensions, while conceptually distinguishable, clearly constrain each other - not all combinations, ie not all points in space, are realisable - it will be extremely hard to find an example such as the way you are wanting to read the ‘wrong means’ passage memorisation example (ie not failing more than ‘wrong means’)
