For every 40 cats that contract a particular ear infection, one will die from it. Scientists have discovered a vaccine that is almost 100 percent effective in preventing this infection. As the risk of death from complications of vaccination is only one death per 1000 vaccinations, it is, therefore, safer for a cat 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 cats that die each year from all causes taken together
B. Whether the vaccine is effective against the infection in household pets other than cats
C. The number of cats that die each year from infections other than the infection in question
D. The likelihood that a cat will contract another infection such as fungal rash
E. The number of cats that will contract the infection in a year.
Which one of the following would it be most helpful to know in order to evaluate the argument?
A. The total number of cats that die each year from all causes taken together
B. Whether the vaccine is effective against the infection in household pets other than cats
C. The number of cats that die each year from infections other than the infection in question
D. The likelihood that a cat will contract another infection such as fungal rash
E. The number of cats that will contract the infection in a year.

Awaiting the OA. It's definitely between D and E.
For every 40 cats that contract a particular ear infection, one will die from it. Scientists have discovered a vaccine that is almost 100 percent effective in preventing this infection. As the risk of death from complications of vaccination is only one death per 1000 vaccinations, it is, therefore, safer for a cat 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 cats that die each year from all causes taken together -We are not worried about the number of cats that would die. We are worried about the effectiveness of vaccine.
B. Whether the vaccine is effective against the infection in household pets other than cats -We are not worried about the different types of pets that might benefit from the vaccine. The argument at hand is concerned about the cats.
C. The number of cats that die each year from infections other than the infection in question -We are not worried about the cats that might die from infections other than the one discussed in the argument. We need to evaluate the effectiveness of the vaccine.
D. The likelihood that a cat will contract another infection such as fungal rash -Correct. Because of vaccine if the cats develop another infection, then there is no use of vaccination.
E. The number of cats that will contract the infection in a year. -This option doesn't talk about the effectiveness of the vaccine.

Although I chose E, I argue that the answer is poorly phrased.
We are interested in the likelihood/probability of a cat contracting the ear infection. The number of cats does not give us any information, unless we know the total population of cats.
