1. Describe a situation in which unconscious incubation worked for you. Describe one in which it did not. Can you explain why it worked in the first case but not in the second?

2. One of the technological problems that we face as a society is the increasing use of plas tics in disposable items. Landfills are becoming more and more expensive and difficult to maintain, and land for new ones can only be obtained at premium prices. Furthermore, the plastics that are dumped in the landfills may release dioxins (toxic chemical sub stances) into the soil.

Of course, many different kinds of plastic exist. Spend 10 minutes writing down pos- sible ways to recycle one-gallon plastic milk jugs. You can assume that the milk jugs are received rinsed out and reasonably clean, but not sterile. Look at your list. Does it reflect fluent thinking, flexible thinking, or both?
