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?

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.

Read the statement and the instructions that follow it,and then make any notes that will help you plan your response.Begin typing your response in the box at the bottom of the screen.
 
The following appeared as part of a newspaper editorial.
 
"Two years ago Nova High School began to use interactive computer instruction in three academic subjects. The school dropout rate declined immediately, and last year's graduates have reported some impressive achievements in college. In future budgets the school board should use a greater portion of the available funds to buy more computers, and all schools in the district should adopt interactive computer instruction throughout the curriculum:"
 
Discuss how well reasoned.., etc.
The author thinks that the interactive computer instruction helped the school reduces their dropout rate, and make their graduates get some impressive achievements in college. The author also suggest all schools to adopt interactive computer instruction. I think the author's opinions have no persuasion. Here is my point of view. First of all, the ineractive computer instruction was only use in three subjects, but the school dropout rate was counted by whole students in this school but that three subjects, so the rate couldn't show the effect by useing ineractive computer instruction. Secound, the editorial did not mentioned any other reason the affect the dropout rate, the ineractive computer instruction may not be the only thing that could affect dropout rate, the economic or poicy can also make some influence. Moreove, the author did not compare the performance of last year's graduates who reported impressive achievements in college and in high school. If the graduate has always got a perfect grade in high school, then the interactive computer instruction would not have too much effects to him. Also, the author did not say that these graduates took the three subject that use interactive computer instruction, so we cannot say there achievements were benefit by the computer instruction. At the last, all school have different conditions, so one school cannot means everthing to others. According to my opinions above, I think the autor's opiots are untenable arguments. 按时间规定写的，后面时间有点不够

Last year a record number of new manufacturing jobs were created.  Will this year bring another record?  Well, any new manufacturing job is created either within an existing company or by the start-up of a new company.  Within existing firms, new jobs have been created this year at well below last year's record pace.  At the same time, there is considerable evidence that the number of new companies starting up this year will be no higher than it was last year and there is no reason to think that the new companies starting up this year will create more jobs per company than did last year's start-ups.  So clearly, the number of new jobs created this year will fall short of last year's record.
