A, B, C, D, E, F are members of a family. They are engineer, stenographer, doctor, draughtsman, lawyer and judge (not in order). A, the engineer is married to the lady stenographer. The judge is married to the lawyer. F, the draughtsman is the son of B and brother of E. C, the lawyer is the daughter-in-law of D. E is the unmarried doctor. D is the grandmother of F. There are two married couples in the family. What is the profession of B?

Let's solve this intuitively by looking for the **Judge**. \n\n1. **The Hook**: The question tells us the **Judge is married to the Lawyer**.\n2. **The Link**: We are explicitly told that **C is the Lawyer**. This means **C's husband is the Judge**.\n3. **The Elimination (Who is C's husband?)**:\n * **A** is out (He is the Engineer).\n * **E** is out (He is the Doctor).\n * **F** is out (He is the Draughtsman).\n * **D** is out (She is the Grandmother, so she cannot be C's husband).\n4. **The Result**: The only person left in the family without an assigned role is **B**. Therefore, **B must be the Judge**.
