Teaching how necessary vs. sufficient reasoning is used for designing experiments, (a) to determine the role of a potential intermediate in a known stimulus producing a known effect.To test for necessity the intermediate activity is blocked in the presence of the stimulus (b); and to test for sufficiency the intermediate activity is produced ectopically in the absence of the stimulus (c). Completion of a sufficient cause is synonymous with occurrence (although not necessarily diagnosis) of disease. A disease may have more than one sufficient cause, with each sufficient cause being composed of several component causes that may or may not overlap. It does not require that all those who possess the contributory cause experience the effect. If you have A is necessary for B it means that every time you have B you will have A, without exception.
