When doctors vaccinate a patient, their intention is to expose him or her to a weakened form of a disease-causing pathogen and thus to make the patient better able to resist the pathogen and less likely to develop a severe form of that disease later.
Method of Reasoning
In this slightly atypical question, we are tasked with finding a situation that parallels the principle from the stimulus. The principle is not explicitly stated, however, so we must first articulate it.
We’re given a situation where a weaker form of something is used to build a tolerance, so this will be our principle: weaker versions of something can be used to build tolerance.
