Question

Select the Venn diagram that best illustrate the relationship between the following classes. Petrol, Car, Electric.

• A. A
• B. B
• C. C
• D. D

Answer 1

Answer:

B. B

We analyze the relationship between the three classes:

• Car

• Petrol

• Electric

  Logical relationship

• Some cars use petrol → Petrol and Car overlap.

• Some cars are electric → Electric and Car overlap.

• Petrol and Electric are different energy types, so they do not overlap.

So the diagram should show:

• Car intersecting with Petrol

• Car intersecting with Electric

• Petrol and Electric not intersecting with each other

  Correct diagram

This pattern matches Option B (the middle circle overlaps with the two side circles, but the side circles do not overlap with each other).

Answer: B
