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.
C、The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the 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.

Turning away from literary realism to write romantic stories about the peasant life and landscape of northern Sweden, in 1909 Selma Lagerlof was the novelist who became the first woman and was also the first Swedish writer to win the Nobel Prize for Literature.
老师～我想请问d选项的A novelist who turned away from literary realism to write romantic stories about the peasant life and landscape of northern Sweden这个是什么结构呀？是做的Selma Lagerlof 的同位语吗？因为我做题的时候觉得这个句子有点奇怪，把 a novelist 一个没有谓语的一句话错误直接排除了。因为之前在做这个题我也是通过主语重复了来排出选项的：Although appearing less appetizing than most of their round and red supermarket cousins, heirloom tomatoes, grown from seeds saved during the previous year—they are often green and striped, or have plenty of bumps and bruises—heirlooms are more flavorful and thus in increasing demand. 所以想问问应该怎么样区别这两个情况。谢谢~

Unlike human runners, who broke the four-minute mile in 1954 and they consistently recorded faster times ever since, horses in classic races such as the Kentucky Derby have had winning times with little improvement:  Secretariat's world-record-breaking Derby tine of 1:59 2/5, for example, was set in 1973 and remained unsurpassed more than a quarter of a century later.
前面是human runners，后面不是也要 those of horses吗？horse也不全是racing的啊，也有分类别。为啥C直接horses？
