Our school district should not spend its money on the new remedial English reading program. After all, our students get all the reading practice they need by studying history and science. The argument above depends on which the following assumptions?

Information that is published is part of the public record.  But information that a reporter collects, and sources that he contacts, must be protected in order for our free press to function free of fear. The above argument is most severely weakened by which one of the following statements? 

Many very effective prescription drugs are available to patients on a “one time only” basis. Suspicious of drug abuse, physicians will not renew a prescription for a medicine that has worked effectively for a patient. This practice denies a patient her right to health.  
Which one of the following is a basic assumption made by the author? 

It takes a good telescope to see the moons of Neptune. I  can’t see the moons of Neptune with my telescope.  Therefore, I do not have a good telescope. 

Rahul: One would have to be blind to the reality of moral obligation to deny that people who believe a course of action to be morally obligatory for them have both the right and the duty to pursue that action, and that no one else has any right to stop them from doing so.   
Richa: But imagine an artist who feels morally obliged to do whatever she can to prevent works of art from being destroyed confronting a morally committed antipornography demonstrator engaged in destroying artworks he deems pornographic. According to your principle, the artist has, simultaneously, both the right and duty to stop the destruction and no right whatsoever to stop it. 
Which of the following, if substituted for the scenario invoked by Richa, would preserve the force of her argument?

Between 1951 and 1963, it was illegal in the country of  Geronia to manufacture, sell, or transport any alcoholic beverages. Despite this prohibition, however, the death rate from diseases related to excessive alcohol consumption was higher during the first five years of the period than it was during the five years prior to 1951. Therefore, the attempt to prevent alcohol use merely made people want and use alcohol more than they would have if it had not been forbidden.  Each of the following, it true, weakens the argument EXCEPT:

Unless they are used as strictly temporary measures, rent control ordinances (municipal regulations placing limits on rent increase) have several negative effects for renters. One of these is that the controls will bring about a shortage of rental units. This disadvantage for renters occurs over the long run, but the advantage-smaller rent increases - occurs immediately. In many municipalities, especially in all those where tenants of rent-control units have a secure hold on political power and can get rent-control ordinances enacted or repealed, it is invariably the desire for short-term gain that guides those tenants in the exercise of that power.   
If the statements above are true, which one of the following can be properly inferred from them? 

A government's proposed 8 percent cut in all subsidies to art groups will be difficult for those groups to absorb. As can be seen, however, from their response to last year's cut,  it will not put them out of existence. Last year there was also an 8 percent cut, and though private fund-raising was very difficult for the art groups in the current recessionary economy, they did survive.  
The reasoning in the argument is flawed because of the  argument

Health insurance insulates patients from the expense of medical care, giving doctors almost complete discretion in deciding the course of most medical treatments. Moreover,  with doctors being paid for each procedure performed, they have an incentive to over-treat patients. It is thus clear that medical procedures administered by doctors are frequently prescribed only because these procedures lead to financial rewards.   
The argument uses which one of the following questionable techniques?
