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.

Research has shown that when speaking, individuals who have been blind from birth and have thus never seen anyone gesture nonetheless make hand motions just as frequently and in the same way as sighted people do, and that they will gesture even when conversing with another blind person.
老师您好，1⃣️make是不是从句individuals的谓语动词呀？2⃣️Nonetheless 这个词在句子中怎么去用呢？3⃣️我选择了C选项，看过正确答案后，我觉得是因为C选项没有从句的谓语动词所以不对，这样理解对不对？4⃣️Have thus 这个have可不可以省略呢？ 谢谢老师～

The passage is primarily concerned with discussing
听了老英的，没懂。就是E问题问某些因素使得期间内增强了Patenting的活跃程度。整篇文章说的就是：最初版权是为了保护风险开发的一种方式，但是半导体工业在1982-1992见挤出了很多没有实际科技含量的版权。虽然版权增加了，但实际上除了保护新技术的价值，还为了“ patents were filed more for strategic purposes, to be used as bargaining chips to ward off infringement suites or as a means to block competitors' products.” 当然我也是C/E纠结，我只是觉得E我不知道无法排除。请给思路。如果可以请将官方解释也给一下

请教Tina老师，先看分组one arm和they（指代starfish）都说得过去，往后看代词先排除了AD，接下来该怎么判断？听之前的讲解说by和with有区别，为什么不能理解为是有时通过过渡补偿？还有最后的差异点在overcompensate和grow的关系，为什么不能理解成grow是overcompensate的附属修饰关系？用并列关系overcompensate和grow extra之间并不是完全独立的？
