I will try and do better if I come up with another at some point.
I have tried to make one of my own and I apologize if this one blows:
**There is a very famous area that used to be very cool, but now it isn’t at all. In fact, it frequently stinks now. Almost nothing else has changed about this area, though.
Where is it and what caused the change?**
I did my best(hope this one works OK).
Some place that was cold a million years ago, and is now warm?
Continental drift?
Climate change?
No to all.
Was it *cool *the same sense that the Fonz is cool?
Does *cool *refer to temperature?
Does cool refer to temperature?
Is the area warm now?
Does stink refer to detection by the olfactory organs in humans?
Is this political?
It’s temperature.
No. 
Is the stink sulfurous compounds?
NO.
When it was cool, was it artificially refrigerated?
Was it used as a storage for food?
Is the stink something rotting?
No to all.
Did it stop being cool :
- within the last 10 years ?
- 10 to 25 years ago ?
- 25 to 100 years ago ?
- 100 to 300 years ago ?
- more than 300 years ago?
- in prehistoric times?
- geological eras ago?
Are humans responsible for the stink?
Is the area a geographical area?
Was a pig farm established in that area?
YES, I think so.
I’ll say NO since it’s more helpful to say no. Everywhere is kind of a geographical area, but I would not categorize this or think of it as one firstly.
No.
Did the area catch on fire between the time it was cool and now?
No, I don’t believe so.
There’s an area of my brain dedicated to coordination and balance.  
…but I get your point, thanks!
There is no trickiness to the word area.
