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.

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
I'm a US citizen and I hold a Washington state Enhanced Driver's License. I'm living in Vancouver for a bit.

Answer:
Can I fly within Canada with a US EDL?
