Anchor: 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.
Entailed: The power digger changed ditch-digging so not as much labor effort is needed.
Contradiction: Power diggers are very slow and require low skill levels.
Contradiction: A woman rides her bike everywhere.
Contradiction: The woman got out of the vehicle.
Contradiction: A lady holding a cat.
Contradiction: To begin with they approached product development in a progressive, iterative manner so as to enable the research and development discoveries more controllable and supportable.
