Let's analyse the conclusion –
Conclusion I:
Some drawings are colors – From the above diagram, it can be seen that the circle of drawings and colors intersect and has some common area between them, which implies that some drawings are colors. So, this conclusion is true based on the given statements.
Conclusion II:
All paints are drawings – From the above diagram, the circle of paint does not lie completely inside the circle of the drawing they have some part in common. Therefore, this conclusion is false.
Conclusion III:
Some drawings are rainbows – From the above diagram, it can be seen that the circle of the rainbow is inside the circle of the drawings, which implies that all rainbows are drawings and some of the drawings are rainbows. So, this conclusion is true based on the given statements.
