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

Solution is here: 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

Now, solve this: My brother who is from Bangladesh got deported from the UK back in 2009 for working illegally while being a student. His old passport was not machine readable.

Since then he has obtained a new clean machine-readable passport (no record of previous visas) and visited countries like Thailand, Singapore, India, Malaysia. He is now planning to visit the US to attend my college graduation.

If he checks the box to say that he was never deported from any countries, is there any way they can find out about this?

Solution:
Deported from UK but got a fresh clean passport. Will the US know?
