Wow. It's a while since I saw this thread. If you are interpreting 'John gets seasick' as meaning he is now suffering from this malady because he has unwisely chosen to go by ship, then I'm happy with your analysis.
That's the trouble with the English language; it can be ambiguous. It made me laugh when I heard this on the news: 'He sailed the Atlantic, single handed.
Most people interpret the puzzle differently; 'John gets seasick' = John knows he will suffer if he goes by ship so he avoids this option.
Nice try! Welcome to the forum.

ps. Sorry, I cannot comment there on your post about the professor because of a promise I made in post 56. I think I dealt with the fault in the student logic in post 50.
And I also demonstrated that you can make statements of this type logically and consistently and make them come true. That's what posts 56 and 65 were all about.
]]>John gets seasick so he must be on the ship.
Cindy had to rent so she is using a car.
Mr. Jones hates flying so he booked the train.
Rachel is therefore on the plane.
Thanks for confirming that.

]]>If we're comparing the distance from my house to Billericay (=24 miles) with the distance to Alpha Centauri ( approx. 24807799074834.8 miles) then you are right.
But if the question was "How many Jimmy Grimbles are there?" then 24 is definitely lots!
Perhaps I'm being too narrow in outlook, but I expect logic questions to have just the one answer.

]]>or can anyone explain why there are not lots of solutions:
There are at most 4! = 24 solutions and 24 is not a lot, is it?
]]>Is there missing information here ? or can anyone explain why there are not lots of solutions:
The Puzzle: Four people are traveling to different places on different types of transport.
Their names are: Rachel, John, Mr.Jones and Cindy.
They either went on train, car, plane or ship.
* Mr.Jones hates flying
* Cindy has to rent her vehicle
* John gets seasick
