3 pages describing some of the explanations or theories for why we age natural selection process, genetics, biological, etc. (ch. 2); age changes in the memory system (ch 4); and the process of partner selection (ch 6). I don't expect you to read everything in these chapters, but a good digest of the summaries at the end of each chapter should be helpful. For a deeper understanding into some concepts you will need to review some portions of the chapter. Be sure and read carefully the lecture and Power Point presentation.
