题目：
A recent sales study indicates that consumption of seafood dishes in Bay City restaurants has increased by 30 percent during the past five years. Yet there are no currently operating city restaurants whose specialty is seafood. Moreover， the majority of families in Bay City are two-income families， and a nationwide study has shown that such families eat significantly fewer home-cooked meals than they did a decade ago but at the same time express more concern about healthful eating. Therefore， the new Captain Seafood restaurant that specializes in seafood should be quite popular and profitable.
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.

最近的销量调查显示Bay City餐馆的海鲜菜肴的消费量比过去五年增加了30%.而现在该市还没有专门经营海鲜菜的餐厅。而且，Bay City的大多数家庭是双收入家庭，一次国家调查显示这类家庭在家做饭的数量比十年前显著减少，同时他们更关注健康饮食。因此，在Bay City开设一家新的专营海鲜食品的C餐馆将会非常受欢迎而且有利可图。
