In the context you're referring I suspect they want you to differentiate between the physical (tangible) things a guest might need - like towels, a TV, a trouser press - as opposed to the services (intangible) they would require - such as room service, a morning wake up call, internet access, the room cleaned in the morning, etc. Basically it's down to the benefits they can touch and those they can't (but are still considered benefits). More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
