Good Yoga.
This reminds me of an old relative puzzle I used to remember which goes like this.
Man on a park bench is looking at a small portrait. You ask him, "Who is that in the picture?"
The man says, "Brothers and sisters, I have none, but that man's father, is my father's son."
Can you tell what person is in the picture?

Yes but you don't have to re-arrange anything.
Logically, it can't be the man on the park bench or you would know it is himself just by looking at the picture he's holding.
Not necessarily if it was an old photograph....
My head feels all right when I'm with you.
Mine too.
Oh no, wait, were you talking dirty?You are making an assumption that's not in the puzzle. You could be facing him and not see the picture or it could be a baby picture. I thought it was the sentence structure that made it confusing but I guess not for everyone.
I believe you have the first relationship wrong.
The question makes the 1st statement: Gerald is Tom's father's brother-in-law.
There are two kinds of brother-in-law; my brother-in-law can be either (a) my wife's brother, or (b) my sister's husband.
So Gerald, being Tom's father's brother-in-law, can be either (a) Tom's mother's brother, or (b) Tom's aunt's husband (= Tom's father's sister's husband).
In your answer, you go with (b) that Gerald = Tom's aunt's husband, and not Tom's wife's sister.
Now, the 3rd statement is: Gerald is Tom's father-in-law's brother.
There is only one kind of father-in-law = your spouse's father.
So, Tom's father-in-law = Tom's wife's father.
So, Gerald is Tom's wife's father's brother.
Or, stating the same thing the other way round: Tom is Gerald's brother's daughter's husband.
So, since Gerald is Tom's father's sister's husband, that puts Gerald and Gerald's brother's daughter in an incestuous relationship.
The 3 statements only work (morally) if you go with the other kind of brother-in-law.
Now, the 3 statements translate as:
- Tom's mother is Gerald's sister;
- Tom's brother married Gerald's daughter;
- Tom married Gerald's neice.
Supplementary point:
My neice is the daughter of my brother /sister. Question: can the daughter of my wife's brother be called my neice, or is she my neice-in-law? Has anybody ever heard or seen (or used) the expression neice-in-law? (Same with nephew-in-law, uncle-in-law, etc.)
