The documents compare and contrast various items and provide reasons for choosing one over the other based on attributes like price, comfort and appearance. Decisions are made to buy the iPhone because it is cheaper than Nokia, to buy a cap because it is prettier than a charro hat, to buy pants because it is winter and they are cheaper than shorts, to buy Nike tennis shoes because they are cheaper than Jordan shoes, and to buy a green shirt because it is more comfortable than the white and blue shirts.
