Must be TrueDiff: Medium
Logic Breakdown
Passage Summary: Most great teachers are a bit quirky, but some normal-acting ones are great too; regardless, every single great teacher is excellent at communicating.
Reasoning: The stimulus establishes that most effective teachers are eccentric, some noneccentric lecturers are effective, and every effective teacher is a good communicator.
Analysis: Since this is a 'Must be True' question, we need to find an overlap between the provided facts. We know that 'every' effective teacher is a good communicator, which means any subset of effective teachers—whether they are eccentric or noneccentric—must also be good communicators. Therefore, we can conclude that most eccentric lecturers who are effective teachers are good communicators, and those few noneccentric effective teachers are good communicators as well. Look for an answer choice that combines these categories without overstepping the 'most' or 'some' quantifiers.
