Select the Venn diagram that best represents the relationship between the following classes.
Earth, Planets, Stars, Saturn
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) →
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.
The Earth and Saturn are both planets, so both circles lie inside the circle of planets
The Earth is not Saturn, so these two circles stay apart inside it
A star is not a planet, so the circle of stars stays outside
One large circle with two separate circles inside, and one circle apart, as in Option (4)
