Part 1. Definition
Given a travel related situation, and given a specific question about the situation, summarize the question into a title
Part 2. Example
The green carriage is of course first class. This would be our first preference with our 5 month old baby in lap, because of the presumably larger toilets for changing and whatnot. However, the baby being a Western white baby... will occasionally babble, screech or cry uncontrollably for a little while.

Speaking in terms of Japanese culture, should we avoid Green class tickets if we are taking aboard a potentially disruptive baby?

Answer: Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car?
Explanation: A person gives a detailed description about a situation where they would prefer to travel on the Shinkansen Green Car but is doubtful if doing that would be against the Japanese train etiquette since they will be traveling with a baby. The question is summarized as Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car? for easy indexing the next time someone searches for a similar phrase
Part 3. Exercise
In Germany there is a brilliant service called packstation. I envy my German friends for this service where packages can be delivered which you can then collect at any time. Typically they are located at very public places (typically gas stations). In Germany you don't longer need to stay home to receive a package.

I will be traveling through Germany soon, where it would help if I could use this service as well. Unfortunately the registration website requires recidency in Germany.

Is there really no way non-residents could use this service?

Answer:
Can you register for a "packstation" in Germany if you are traveling through Germany?
