If Osaka is visited second, how many of the six cities could be the one visited fourth?

Why is it wrong that 4 can be visited 3rd if o is visited 2nd
Drawn out it you could have this 4 scenarios

- none of the rules are broken.
S is out
- J is only in when it's 3rd
- H/T are not directly next to each other and are in
I'm confused as to why then 4 is the wrong answer

We know that if O is in, S is out. We have H, T, M, and J.
We know that if J is in, J must be in 3. Clearly, then, J can't be in 4.
This means that only H, T, or M can be in 4, and this is why (C) is correct because it says that 3 of the 6 cities could be visited 4th.
Does this make sense? Let us know if you have any other questions!

Oh I'm an idiot. I was reading it as which fab be in 3 as you can tell from my diagram. Thanks

But if M was selected for 4, then only H or T could be in 1, and the rule says that HT both have to be on the trip. Am I missing something?
