one page essay about mind and body philosophical problems

Please I need an one page answer for this question please:

Q: Chalmers distinguishes a hard problem from an easy problem concerning our understanding of the mind. What is the hard problem? Why is it hard? In what respect is it a problem about knowing what states of consciousness are like? He says that states of consciousness cannot be understood in terms of structure and function. Why does he say this? In what respect is his claim similar to Searle’s claim that intentionality cannot be understood in terms of formal function and structure?

– I will attach the chapter that has the answer for this question in the attachments.
