Select the Venn diagram that best represents the relationship between the following classes.
Authors, Teachers, Men
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) →
In a Venn diagram two circles overlap when some members belong to both classes, one circle lies inside another when every member of the first belongs to the second, and circles stay apart when the classes have no common member.
Some authors are teachers and some are not, so these two circles overlap
Some authors are men, and some teachers are men
A man can be an author and a teacher at the same time, so all three circles overlap, with a common region, as in Option (1)
