Take the following as truth: Consider the transformation of ditch-digging from a relatively slow and somewhat imprecise process involving several ordinary shovels, much labor effort, and low skill levels to a faster and more precise process often involving a single power digger controlled by a skilled operator.
Then the following statement: "The power digger changed ditch-digging so not as much labor effort is needed." is true, false, or inconclusive?
Answer: True
