Mayor of Smalltown: Instituting high taxes on sodas, which are currently untaxed in Smalltown, has been shown in the past year to encourage people to reduce their intake of soda and live healthier lifestyles. Because the effects of such taxes on local businesses have not yet been determined, though, I believe we should wait before implementing such a tax.
Activist: Your position is inconsistent with previous actions you have taken. You have implemented many laws that have decreased local businesses' revenues in order to help consumers, so concern for local businesses cannot be the true reason you refuse to pass this law now.
The activist's argument is flawed because it fails to consider that
A. the health effects of some types of sodas may be different than the health effects of others. -- Irrelevant -- the varying severity of effects is not relevant
B. it is possible that the mayor believes lower soda consumption is an inefficient way to encourage healthier lifestyles. -- Irrelevant
C. soda consumption has been strongly linked to rates of obesity and shorter lifespans. -- Out of scope
D. the effects of taxes on local businesses may not be immediately apparent in all cases. -- Irrelevant
E. it is possible to weigh known drawbacks against known benefits, but not possible to weigh unknown drawbacks in the same way.-- Correct
You have implemented many laws that have decreased local businesses' revenues in order to help consumers--- > weigh known drawbacks against known benefits
Because the effects of such taxes on local businesses have not yet been determined, though, I believe we should wait before implementing such a tax. --> but not possible to weigh unknown drawbacks in the same way
This question is similar to an official question on doctors prescribing drugs whose side-effects are not known
