这几道题都作错了，请各位朋友帮忙解释一下。谢谢！ GWD1-Q40: Until mow, only injectable vaccines against influenza have been available. Parents are reluctant to subject children to the pain of injections, but adults, who are at risk of serious complications from influenza, are commonly vaccinated. A new influenza vaccine, administered painlessly in a nasal spray, is effective for children. However, since children seldom develop serious complications from influenza, no significant public health benefit would result from widespread vaccination of children using the nasal spray. Which of the following is an assumption on which the argument depends?
- Any person who has received the injectable vaccine can safely receive the nasal-spray vaccine as well.
- The new vaccine uses the same mechanism to ward off influenza as jnjectable vaccines do.
- The injectable vaccine is affordable for all adults.
- Adults do not contract influenza primarily from children who have influenza.
- The nasal spray vaccine is mot effective when administered to adults.

GWD3-Q31: Although most smoking-related illnesses are caused by inhaling the tar in tobacco smoke, it is addiction to nicotine that prevents most smokers from quitting. In an effort to decrease the incidence of smoking-related illnesses, lawmakers in Sandonia plan to reduce the average quantity of nicotine per cigarette by half over the next five years. Unfortunately, smokers who are already addicted to nicotine tend to react to such reductions by smoking correspondingly more cigarettes. The information above most strongly supports which of the following predictions about the effects of implementing the Sandonian government’s plan? - The average quantity of tar inhaled by Sandonian smokers who are currently addicted to nicotine will probably not decrease during the next five years.
- Sandonian smokers who are not already addicted to nicotine will probably also begin to smoke more cigarettes during the next five years than they had previously.
- The annual number of Sandonian smokers developing smoking-related illnesses will probably decrease during the next five years.
- The proportion of Sandonians attempting to quit smoking who succeed in that attempt will probably decrease during the next five years.
- The number of Sandonians who quit smoking during the next five years will probably exceed the number who quit during the last five years.
------------------------------------------------------------------------------------------------------------ GWD3-Q32: Newspaper editorial: In an attempt to reduce the crime rate, the governor is getting tough on criminals and making prison conditions harsher. Part of this effort has been to deny inmates the access they formerly had to college-level courses. However, this action is clearly counter to the governor’s ultimate goal, since after being released form prison, inmates who had taken such courses committed far fewer crimes overall than other inmates. Which of the following is an assumption on which the argument depends? - Not being able to take college-level courses while in prison is unlikely to deter anyone from a crime that he or she might otherwise have committed.
- Former inmates are no more likely to commit crimes than are members of the general population.
- The group of inmates who chose to take college-level courses were not already less likely than other inmates to commit crimes after being released.
- Taking high school level courses in prison has less effect on an inmate’s subsequent behavior than taking college-level courses does.
- The governor’s ultimate goal actually is to gain popularity by convincing people that something effective is being done about crime.
