OG13-107. Although the discount stores in Goreville’s central shopping district are expected to close within five years as a result of competition from a SpendLess discount department store that just opened, those locations will not stay vacant for long. In the five years since the opening of Colson's, a nondiscount department store, a new store has opened at the location of every store in the shopping district that closed because it could not compete with Colson’s. Which of the following, if true, most seriously weakens the argument? A. Many customers of Colson’s are expected to do less shopping there than they did before the SpendLess store opened. B. Increasingly, the stores that have opened in the central shopping district since Colson’s opened have been discount stores. C. At present, the central shopping district has as many stores operating in it as it ever had. D. Over the course of the next five years, it is expected that Goreville’s population will grow at a faster rate than it has for the past several decades. E. Many stores in the central shopping district sell types of merchandise that are not available at either SpendLess or Colson’s. 不太理解的地方是， 1. 官方解釋說在colson開幕後 那些無法競爭的店家關閉 隨後持續增加discount stores, 而spendless 開了後就不會再有discount store的需求， 請問要怎麼判斷出不會再有其他需求呢？ 2.選項B 持續增加的discount store 表示可能不會再有店家被取代， 與題目現況比較 這些discount stores會在五年內預期關閉因為無法與Spendless競爭， 要怎麼weaken 倒閉之後的位置不太可能會有其他店家open呢？ 這裡是否只要是能夠weaken 類比例子不成立即可 我根本無需將答案套入Spendless? 還請好心人解惑....謝謝>< --
