    When a consumer finds that something he or she bought is faulty or in some other way does not live up to what the producer says for it, the first step is to present the warranty(保单),or any other records that might help, at the store of buying. In most cases, this action will produce results.

    However, if it does not, there are various means the consumer may use to gain satisfaction. A simple and common method used by many consumers is to complain directly to the store manager. In general, the “higher up” the consumer takes his or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumer's favour, taking it as true that he or she has a just right.

    Consumers should complain in person whenever possible, but if they cannot get to the place of buying, it is acceptable to phone or write the complaint in a letter.

    Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can show clearly what is wrong with what was bought in question. If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example, “The left speaker does not work at all and the sound coming out of the right one is unclear” is better than “This stereo(立体音响) does not work.”

    The store manager may advise the consumer to write to the producer, if so, the consumer should do this, stating the complaint as politely and as firmly as possible. But if a polite complaint does not achieve the expected result, the consumer can go a step further. He or she can threaten to take the seller to court or report the seller to a public organization responsible for protecting consumers' rights.

阅读材料，回答问题。

材料一  明洪武三十年二月会试，以翰林学士刘三吾等为考试官，因所录51名全系南方人，故又称南榜。会试落第的北方举人因此联名上疏，告考官刘三吾偏私南方人。明太祖朱元璋命于落第试卷中再择卷复阅，增录北方人。但经复阅后上呈的试卷文理不佳，并有犯禁忌之语。有人上告说刘三吾等人故意以陋卷进呈。朱元璋大怒并亲自策问，取录61名。因所录者全系北方人，故又称北榜。此事件开明朝分南北取士之先例，此后遂成定制。
