Identify Each Speaker That Gives an Argument for Her Position

Identify each speaker that gives an argument for her position in the following passage.
mother:If you are looking for a wise investment,try real estate.The price of housing has always risen faster than the rate of inflation.
daughter:Maybe,but I'm skeptical.What's risen faster than the rate of inflation is the cost of land,not the cost of the structures put on it.Since the population isn't growing and the demand for land is declining,real estate may not be such a great investment any more.
