You should explaine each for a paragraph.

Real Estate and Commodities:  You can choose any investment vehicle you believe best suits the needs of your client.  Write a paragraph stating why you have chosen to invest in this particular security or group of securities.  If you are using funds, make sure you include all required data.  If it is a stock, make sure to include why this particular company is the best choice.
