Read the following introduction and identify the kind of introduction adopted. Americans are incredibly lazy. Instead of cooking a simple, nourishing meal, we pop a frozen dinner into the oven. Instead of studying a daily newspaper, we are contented with the capsule summaries on the network news. Worst of all, instead of walking even a few blocks to the local convenience store, we jump into our cars. This dependence on the automobile, even for short trips, has robbed us of a valuable experience—walking. If we drove less and walked more, we would save money, become healthier, and discover fascinating things about our surroundings.
