题目：
The following appeared in a memo from the new vice president of Sartorian， a company that manufactures men's clothing.
"Five years ago， at a time when we had difficulties in obtaining reliable supplies of high quality wool fabric， we discontinued production of our alpaca overcoat. Now that we have a new fabric supplier， we should resume production. This coat should sell very well： since we have not offered an alpaca overcoat for five years and since our major competitor no longer makes an alpaca overcoat， there will be pent-up customer demand. Also， since the price of most types of clothing has increased in each of the past five years， customers should be willing to pay significantly higher prices for alpaca overcoats than they did five years ago， and our company profits will increase."
Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.
中文翻译：
五年前，当我们在获取可靠的高质量羊毛毛料的渠道方面存在困难的时候，我们停止了高档羊毛外衣的生产。现在有了新的毛料供应商，我们应该重新开始生产。这种外衣应该会卖的很好：因为我们已经五年没有供应羊毛外衣了，而且由于我们的主要竞争对手已不再生产羊毛外衣，消费者将有很迫切的需求。而且，由于过去五年中多数种类的服装价格每年都在上涨，消费者应该愿意花比五年前高的多的价格购买羊毛外衣，从而我们公司的利润将会上升。
