MediumOriginal questionWhich diagram best represents the relationship among Teachers, Parents and Human beings?
Show the answer and explanation
CorrectNot quiteAnswer B
Correct answer: B
Explanation
Every teacher and every parent is a human being: both circles lie inside Human beings.
Many teachers are parents, some teachers are not parents and some parents are not teachers: Teachers and Parents overlap.
So two overlapping circles sit inside a larger circle.
Worth noting
Three mutually overlapping circles would allow teachers who are not human beings. Two separate circles inside a larger one forgets that a teacher can also be a parent.
