题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.
 
The argument above requires which of following assumptions?

选项:

A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.

D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

Investment banks often have conflicting roles.  They sometimes act for a client company by raising capital from other investment institutions as advantageously as possible, but their analysts also sometimes send unfavorable reports on the financial health of companies for whom they are raising capital to other clients who wish to make investments.  Analyses of companies' financial health need to be unbiased if an investment bank is to achieve long-term success.
 
If the statements above are true, which of the following practices, if adopted by an investment bank, would hinder its long-term success?
读原文：投资银行角色是矛盾的，他们有时候作为当事人通过提高资金从另外一个银行，但是他们的分析家有时候发布不好的财政消息去那些他们要提高资金的去另外一些人，那些人是要一些投资的。分析家需要无偏见当追求一个长期的成功时。 原文的事件：角色矛不矛盾，提不提高资金，发不发布不健康的消息，追求长期成功公不公正。 选项：A：提高资金对当事人的时候还做了什么事（说过点留着） B：使用什么去决定是最好的提高资金对当事人（说过点留着） c：分享这个项目，这个项目是提高资金的与其他公司（杀） d:确保这个争论，在分析家与那些人，那些人人是提高资金的怎么招解决了靠什么 （文章没提过。杀） E:监测现有的分析家预测的成功与失败，来保证将来的预测 （杀） 英老师到这我比不出来了

In Berinia, the age at which people could begin to drink alcohol legally used to be 18.  In 1990, in an attempt to reduce alcohol consumption and thereby to reduce alcohol-related traffic deaths among Berinians under 21, the legal drinking age was raised to 21.  Alcohol-related traffic deaths among people under 21 have decreased significantly since 1990.  Nevertheless, surveys show that people in that age-group drink just as much alcohol as they did before 1990.
 
Which of the following, if true of Berinia, most helps to resolve the apparent discrepancy?
老師 想請你用這兩題比較一下 到底什麼算是發散 什麼是不算發散 相关考题（ID 230）： Five years ago, as part of a plan to encourage citizens of Levaska to increase the amount of money they put into savings, Levaska's government introduced special savings accounts in which up to $3,000 a year can be saved with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five. Millions of dollars have accumulated in the special accounts, so the government's plan is obviously working. Which of the following, if true, most seriously weakens the argument? A substantial number of Levaskans have withdrawn at least some of the money they had invested in the special accounts. Workers in Levaska who already save money in long-term tax-free accounts that are offered through their workplace cannot take advantage of the special savings accounts introduced by the government. The rate at which interest earned on money deposited in regular savings accounts is taxed depends on the income bracket of the account holder. Many Levaskans who already had long-term savings have steadily been transferring those savings into the special accounts. Many of the economists who now claim that the government's plan has been successful criticized it when it was introduced. 上面這題我直接去BCE 比較AD A 說一群人把錢從那裏取了出來 那裏的錢就少了 駁斥 D 又有錢存到那個帳戶裡了 是支持 刪 我選了A 後來經高人指點 已經明白為何D是駁斥 (高人對D的解釋是 政府的目的是要大家存錢 而大家只是把存的錢轉去特別帳戶 總的存款量並無增加 所以政府目的並未達到 駁斥 順便請問這個思路對否) 但是我想知道的是如何去A 老管錄音說因為原文討論的是存不存錢 收不收利息 和原文無關 我留了A 就是主觀推測了 好 我接受這個解釋 那下面這題 我馬上就去掉BCDE 原因如下 A:說所有人 原文所討論的範圍也包括 暫時先留 B:說在哪裡喝酒 跟原文無關 直接去 CDE太土鱉 直接去 所以只剩一選項 那就是A 後又經高人指點(不同高人) 因為在遠離家的地方喝 就需要交通 就有車禍 我完全可以理解為什麼 但這就沒有發散 主觀了嗎? 因為選了B的話 表示得主觀認為不在家喝就得開車 或者說在外面喝就得開車回家 所以才有車禍 所以到底什麼才是發散不發散? 可以用老管的"已知信息的定義"來解決這個問題嗎? 請老師告訴我 我的問題是什麼?

If (y+3)(y-1) – (y-2)(y-1) = r(y-1), what is the value of y?
(1)     r2 = 25
(2)     r = 5
本人的问题主要是：为什么条件1，不充分？ 1 分析题干， 得5（y-1)=r(y-1), 因此，当y=1,r可以为任何数；y~=1,r=5. 【问题】：r可以为任何数也包含r=5的情况，那么这一分析的结论是不是不够严密，有问题？那怎么分析已经给的已知条件才算严谨？ 2 分析条件1，r=5或r=-5 当r=5,y可以是任何数，甚至当y=1是也是成立的，但根据题干的分析，y不应该为1 当r=-5，y=1 如果当r=5时，y可以取1，那么取这两种情况下的交集，可以确定y=1.这样看来条件1就充分了。可是正确答案是E。 3 问老师，以上本人的分析漏洞在哪里？还是原题的讲解也有不严密之处。 望老师不吝赐教，谢谢！
