The vaccine for yersiniosis, a bacterial disease that affects both dogs and humans, has been available hitherto in the form of a nasal spray. Pet owners who are at risk of contracting yersiniosis get themselves inoculated, but are often unwilling to put their dogs through the trouble of getting a nasal spray. A new yersiniosis vaccine that can be administered orally is effective for dogs. However, since this disease is rarely severe in dogs, widespread inoculation of dogs using the oral yersiniosis vaccine will have no significant public health benefit.
Which of the following is an assumption on which the argument depends?
A Any person who has received the nasal-spray vaccine can safely receive the oral vaccine as well.
B Yersiniosis is one of the most common diseases that affect pet dogs.
C The oral vaccine is less expensive than the nasal-spray vaccine.
D Humans do not contract yersiniosis primarily from dogs that have yersiniosis.
E The oral and nasal-spray vaccines are equally effective.

The answer is D.
Let's break the argument down logically: since dogs who get infected don't get severely sick, there is not much point - from the standpoint of public health - in inoculating them. this assumes that nothing else bad can happen to public health from dogs being sick. Since we know the disease affects dogs and humans, this means we need to assume that (D) Humans do not contract yersiniosis primarily from dogs that have yersiniosis.
As always, we can answer by elimination as well:
A Any person who has received the nasal-spray vaccine can safely receive the oral vaccine as well. irrelevnat - the conclusion is that dogs don't need to receive the oral vaccine, not humans
B Yersiniosis is one of the most common diseases that affect pet dogs. no - in fact, if this were not true it would strengthen the argument: if dogs don't get sick, no reason to inoculate them in the first place.
C The oral vaccine is less expensive than the nasal-spray vaccine. if anything, weakens the argument, in that it makes using the oral vaccine more attractive
D Humans do not contract yersiniosis primarily from dogs that have yersiniosis. Yes! if this were not the case, then not inoculation dogs would be a bug problem, because humans would be infected. We need this assumption to be true!
E The oral and nasal-spray vaccines are equally effective. not necessary to assume this - in fact, if the oral were less effective, it would strengthen the argument by making it less attractive

Argument there is no public benefit ( no human benefit) by oral vaccination of dogs
Evaluate options
A Any person who has received the nasal-spray vaccine can safely receive the oral vaccine as well- talking about person vaccination so this choice irrelevant
B Yersiniosis is one of the most common diseases that affect pet dogs- doesn't address dog vaccination concern
C The oral vaccine is less expensive than the nasal-spray vaccine- no matter of cost is discussed
D Humans do not contract yersiniosis primarily from dogs that have yersiniosis- if this is true then there is no benefits from dog vaccination.this is correct answer
E The oral and nasal-spray vaccines are equally effective- dogs don't use nasal vaccination so irrelevant
