- Brother
Show the answer and the worked solution
Correct answer: B. Father
Worked solution
- 'The only son of my father' is the speaker himself (he is his father's only son).
- So the photograph is of the speaker's son.
- The man is the boy's father.
Answer: Father.
The idea
Resolve the innermost phrase first and replace it with a single person, then work outwards. 'The only son of my father' is the speaker whenever he is male and has no brother.
Shortcut. Replace 'the only son of my father' with 'me': the photograph shows 'the son of me', so the speaker is the father.
Common trap. "Brother" — reading 'son of my father' as a brother; the word 'only' rules a brother out, so the phrase points back to the speaker.
