Thank you for that information. Can you tell me something about its demographics? 
 Interesting, What else can you tell me about Puerto Rico's demographics before my trip? 
 You're welcome, and I hope you have great weather on your trip to Puerto Rico! 
 I can't say for sure, but the 'nature' of relationships between Puerto Rico and the US may have some relation the that. 
 Tell me more about its infrastructure.
