題目：
"Recently， butter has been replaced by margarine in Happy Pancake House restaurants throughout the southwestern United States. This change， however， has had little impact on our customers. In fact， only about 2 percent of customers have complained， indicating that an average of 98 people out of 100 are happy with the change. Furthermore， many servers have reported that a number of customers who ask for butter do not complain when they are given margarine instead. Clearly， either these customers do not distinguish butter from margarine or they use the term 'butter' to refer to either butter or margarine."
Write a response in which you discuss one or more alternative explanations that could rival the proposed explanation and explain how your explanation（s） can plausibly account for the facts presented in the argument.
中文翻譯：
Happy Pancake House 在美國西南部的餐廳用人造黃油代替了天然黃油。但是這種改變對顧客的影響非常小因為只有大約2%的顧客投訴，這說明100 個人中有98 人對于這種替換是樂于接受的。而且，很多服務生報告說很多仍然要了天然黃油的顧客在被給予人造黃油的時候并沒有投訴。顯然，這些顧客要么分不清天然黃油和人造黃油，要么是用"天然黃油"這個詞匯來指天然黃油或人造黃油。
寫一篇回應，在其中討論一個或數(shù)個可以和文中的解釋相競爭的他種解釋（原因），并說明你提出的解釋是如何可信的解釋和說明文中呈現(xiàn)的事實的。
