In the following figure, the square represents psychologists, the triangle represents chemists, the circle represents actors, and the rectangle represents mothers. Which set of letters represents mothers who are NOT actors?

- AB
- BG
- CD + E
- DB + C
Solution & Step-by-step Explanation
Let's identify the required regions based on the geometric representations:
1. Mothers: Represented by the large vertical rectangle. The letters inside this rectangle are C, D, E, G.
2. Actors: Represented by the circle. The letters inside the circle are E, F, H, D.
3. We need to find the region representing mothers who are NOT actors. This means we look for the letters inside the rectangle but outside the circle.
4. Removing the overlapping circle letters (D and E) from the rectangle letters (C, D, E, G), we are left with G and C.
5. Looking at the given options, G is presented individually as an answer choice.
