If the magazine' s circulation continues to rise as it has over the last ten years, in another ten years it will be the largest-selling martial arts magazine in the world. Unfortunately, it has now become clear that the magazine' s publisher will not allow the managing editor to make the changes she has proposed, and without these changes, the magazine' s circulation will not rise as quickly over the next ten years as it has over the last ten. So the magazine will not be the largest-selling martial arts magazine ten years from now. The argument's reasoning is flawed because the argument ["equates a reduction in the rate at which the magazine's circulation is increasing with a decline in the magazine's circulation", 'treats an occurrence that will ensure a certain outcome as something that is required for that outcome', "identifies some changes required for the magazine's circulation to continue its rapid increase and concludes from this that no other changes are needed", 'draws a conclusion that simply restates a claim that is presented in support of that conclusion']
