I think we must make important decisions soon. We need to decide how to develop our natural resources and mineral wealth without destroying the wilderness and harming the wild life. What is decided on now will affect the generations to come. For today's lecture, I'll first show you some pictures of Alaska's wilderness as it was 20 years ago, foil owed by some of the wilderness as it is today. Then I'd like to outline my specific suggestions for the preservations of Alaska.

In the test of short-term memory, non-smokers made the fewest errors, but deprived smokers committed fewer errors than active smokers. The test required people to read 2 passages, than answer questions about them. Non-smokers remembered 19% more of the most important information than active smoker, and deprived smokers did better than those who had smoked a cigarette just before testing. Active smokers tended not only to have poorer memories but also to have trouble separating important information from insignificant details.
