The Classic Five-Part Structure 1. Introduce the topic to be argued. Establish its importance. 2. Provide background information so readers will be able to follow your discussion. 3. State your claim (your argumentative thesis) and develop your argument by making a logical appeal. Support your claims with facts, opinions, and examples. If appropriate, mix an emotional appeal or an appeal to authority with your logical appeals. 4. Acknowledge counterarguments and treat them with respect. Rebut these arguments. Reject their evidence or their logic or concede some validity and modify your claim accordingly. Be flexible; you might split the counterarguments and rebut them one at a time at different locations in the paper, or you might begin the paper with a counterargument, rebut it, and then move on to your own claim. 5. Conclude by summarizing the main points of your argument. Then remind readers of what you want them to believe or do. Give them something to remember. The Problem-Solution Structure I. There is a serious problem. A. The problem exists and is growing. (Provide support for argument.) B. The problem is serious. (Provide support.) C. Current methods cannot cope with the problem. (Provide support.) II. There is a solution to the problem. (Your claim goes here.) A. The solution is practical. (Provide support.) B. The solution is desirable. (Provide support.) C. We can implement the solution. (Provide support.) D. Alternate solutions are not as strong as the proposed solution. (Review – and reject – competing solutions.) In both cases, you know before you begin writing whether you will use an inductive (analytic) or deductive (synthetic) arrangement for your argument. The decision to move inductively or deductively is about strategy. Induction moves from support to a claim. Deduction moves from a claim to support – to particular facts, opinions, and examples. This is the preferred form for most writing in the humanities. You can position your claim at the beginning, middle, or end of your presentation. In the problem/solution structure, the claim is made only after the writer introduces a problem. With the five-part structure, you have more flexibility in positioning your claim. One factor that can help determine placement is the likelihood of your audience agreeing with you. When your audience is likely to be neutral or supportive, making your claim early on will not alienate readers (synthetic presentation). When your audience is likely to disagree, placing your thesis at the end of your presentation allows you time to build a consensus, step by step, until you reach your conclusion (analytical presentation).

ANSWER: Concept Review: Calculating Doubling Time Chapter 04 Homework http://session.masteringenvironmentalscience.com/myct/assignmentPrintV… 7 of 13 5/21/2014 7:59 PM Can you calculate doubling times and growth rates for exponentially growing populations? Remember that the doubling time (in years) for an exponentially growing population is estimated by dividing 70 by the growth rate of the population (as a percentage): Doubling time (in years) = 70 / annual growth rate (%) Part A Drag the values on the left to the appropriate blanks on the right to complete the sentences. Not all values will be used. ANSWER: Concept Review: Calculating Population Growth Rates Populations grow larger from births and immigration and grow smaller from deaths and emigration. The growth rate for a population is determined by adding the birth rate and the immigration rate, and then subtracting the death rate and the emigration rate (all rates expressed as the number per 1,000 individuals per year): (birth rate + immigration rate) (death rate + emigration rate) = growth rate Positive population growth rates lead to population increases, and negative population growth rates lead to population declines. Part A Suppose you are studying a population with the following characteristics: Birth rate = 14 per 1,000/year Death rate = 6 per 1,000/year Immigration rate = 5 per 1,000/year Emigration rate = 1 per 1,000/year What is the growth rate for this population?
