Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Input: Consider Input: As seen in the Politics SE:

Right now, you can jump on a ferry in France, head over to Cork, drive up to Belfast and catch the ferry to Liverpool, without ever showing your passport to anyone. It seems inconceivable that this arrangement could be maintained if and when the UK leaves the EU.

Best I'm aware you'd need to show your passport before boarding in France, in much the same way that you do when taking the Eurostar to London. Because Ireland, like the UK, isn't part of the Schengen zone.

Which is it?

Bonus question: would you also need to show your passport to go from Belfast to Liverpool, or is that second assertion factual?

Output: Do you need a passport to take the ferry from France to Ireland?

Input: Consider Input: I am storing a suitcase full of stuff at my college. At the storage site, I saw how luggage was stacked one on top of another. As some of the suitcases are probably very heavy, and as my suitcase will be stored there for a few months, I am wondering about the correct way to store the luggage to minimize the damage for the suitcases at the bottom of the pile. Should the cases be stacked sideways (as depicted in this image) or should they be stacked with the largest face pointing up (as depicted in this image)? Or would the two storage methods be equivalent? Finally how sturdy should a typical relatively new soft-case suitcase be?

Output: How should I be stacking luggage?

Input: Consider Input: I have a flight with one leg operated by Air France and the other one by JAL. Apparently, I cannot choose my seat from the Air France website and cannot check-in online on the JAL website. Is there any way for me to choose my seat?

Also, I will Premium Economy on JAL, are all seat of equivalent quality like in Business or is there bigger differences between seats like in Economy?
Output: How to choose seat with JAL when online check-in is not available?
