For every 50 dogs that contract a certain disease, one
will die from it. A vaccine exists that is virtually
100 percent effective in preventing this disease. Since
the risk of death from complications of vaccination is
one death per 5,000 vaccinations, it is therefore safer for
a dog to receive the vaccine than not to receive it.
Which one of the following would it be most helpful
to know in order to evaluate the argument?
(A) the total number of dogs that die each year from
all causes taken together
(B) whether the vaccine is effective against the
disease in household pets other than dogs
(C) the number of dogs that die each year from
diseases other than the disease in question
(D) the likelihood that a dog will contract another
disease such as rabies
(E) the likelihood that an unvaccinated dog will
contract the disease in question
will die from it. A vaccine exists that is virtually
100 percent effective in preventing this disease. Since
