Teacher: Given a travel related situation, and given a specific question about the situation, summarize the question into a title
Teacher: Now, understand the problem? If you are still confused, see the following 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: Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car?
Reason: 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 instance: I'm an American traveling to Central America for the first time this summer. I'll be entering Costa Rica and Panama.

My Spanish is pretty good, but not native, and I wouldn't mind using it, but as a general rule, should I try to address the border officer in their language when I can or should I stick to English?

How it went: I transited Costa Rica without being asked any questions at all, but I entered remote Bocas del Toro using only Spanish (and let me tell you, it was much smoother for me than for my English-only traveling companions) and exited Bocas in English (different officer).

All in all, I followed the advice here, and answered in the language I was addressed in.

Student:
In what language should I address foreign customs and immigration?
