题目：
The following appeared in a memorandum from the owner of Movies Galore， a chain of movie-rental stores.
"Because of declining profits， we must reduce operating expenses at Movies Galore's ten movie-rental stores. Raising prices is not a good option， since we are famous for our low prices. Instead， we should reduce our operating hours. Last month our store in downtown Marston reduced its hours by closing at 6：00 p.m. rather than 9：00 p.m. and reduced its overall inventory by no longer stocking any DVD released more than five years ago. Since we have received very few customer complaints about these new policies， we should now adopt them at all other Movies Galore stores as our best strategies for improving profits."
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.

由于利润下降，我们必须压缩G公司的十家录像租赁店的营业开支。涨价并不是一个好选择，因为我们就是因特价销售而知名的。因此我们应该缩短营业时间。上个月我们位于闹市区Marston的店营业时间从以前的9点缩减到下午6点，并通过不再保留发行5年以上的电影来减少总库存量。由于我们所收到的客户关于这些新政策的投诉很少，我们应该在所有G公司的商店实施这些政策作为增加利润的最好策略。
