Following several years of declining advertising sales, the Greenville Times reorganized its advertising sales force two years ago. Before the reorganization, the sales force was organized geographically, with some sales representatives concentrating on city-center businesses and others concentrating on different outlying regions. The reorganization attempted to increase the sales representatives' knowledge of clients' businesses by having each sales representative deal with only one type of industry or of retailing. After the reorganization, advertising sales increased.
In assessing whether the improvement in advertising sales can properly be attributed to the reorganization, it would be helpful to find out each of the following EXCEPT:
Two years ago, what proportion of the Greenville Times's total revenue was generated by advertising sales?
Has the circulation of the Greenville Times increased substantially in the last two years?
Has there been a substantial turnover in personnel in the advertising sales force over the last two years?
Before the reorganization, had sales representatives found it difficult to keep up with relevant developments in all the types of businesses to which they were assigned?
Has the economy in Greenville and the surrounding regions been growing rapidly over the last two years?
情景：Greenville Times在两年前重组了广告销售部门。现在的现象是，在重组之后，广告的销售上升了。
推理：
前提：reorganization和advertising sales increased之间存在正相关关系
结论：The improvement in advertising sales can properly be attributed tothe reorganization
答案预估：
其它能解释为何“提高了广告销售”的原因。
“重组导致广告销售提高”的其它必要条件（常理上能保真推理出的一切结果）。
选项分析：
A选项：Correct. 两年以前，广告销售的收入占Greenville Times总收入的百分比是多少？ 本选项没有提及reorganization，它给出的是广告销售收入和总收入之间的关系，不能评估相关因果推理。
B选项：近两年来，Greenville Times的传播量有没有显著的上升？本选项给出了advertising sales increased的另一个可能的原因，即，传播量增大也可能导致广告销售收入上升。
C选项：近两年在广告销售部门的人事问题上有没有重大变动？如果有，证明重组是有意义的，如果没有，就证明重组是没意义的。建立了因和果之间的相关性。
D选项：在重组之前，销售代表有没有发现很难跟上指派给他们的所有类型的商业任务的相关发展进度？本选项同(C)。
E选项：在Greenville和其周边的地区的经济是不是在过去的两年内是否上涨迅速？本选项给出了advertising sales increased的另一个可能的原因，即，经济变好可能导致广告销售收入上升。
重组前，销售按照地区分组；重组后，销售按照客户type来分组。
下面哪个选项不能对了解销售业绩提升与改组的关系 有帮助？（能，评价是有关或者无关，都是对的，类似data sufficiency）
A：公司里总收入中，有多少是广告销售收入？（知道多少不能帮助我们了解 销售业绩的提升与改组是否有关）
E：Greenville的经济变好了。说明销售业绩提升与改组无关，有帮助
