So what precisely is it that you have to do? I wonder whether you need to use the articles you are given to write a response about your own beliefs on duck hunting, as this is normally what teachers would expect you to do if you have been given articles for and against. I have included a link below about writing an argumentative essay, but let me offer the following steps to help you in this.
Firstly, you need to read the articles really well and make sure you understand them. Then you need to identify the points that they make in support of what they are arguing. Why do they think duck hunting is a good idea? Why do they think it is not a good idea? Highlight each argument and note it down, linking it to quotes that are used. Then, before writing, have a think about these arguments. Do you agree with them? Which side of the issue is stronger do you think? Do you have any arguments to add either for or against from your own point of view?
After taking these steps you are ready to write your essay. I would suggest a five paragraph essay format, with an introduction, then arguments for duck hunting, then arguments against, your own belief with any additional arguments you can think of, then a paragraph to round it off with a conclusion. Make sure you include quotes where appropriate from the articles.
Hope this helps and good luck!
