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 TOHM HOTM TOJH TOMH - 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

@Kanyin,

Happy to help.

We know O is in 2

_ O _ _ | S _

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
