Answer:
A. a quotation from the director of an overcrowded animal shelter.
Explanation:
Since the claim that has to be supported relates to adapting a dog from the shelter to solve the overpopulation problem, a quotation from the director of an overcrowded shelter would most likely be relevant to the claim, by lending it more credibility by including an authentic source who has first-hand experience of the problem presented in the claim, and is in a position to comment on the given solution.
The other options are not correct because:
- The statistic about the number of cats and dogs living in the wild worldwide does not relate to the shelter and adopting dogs.
- Examples of exotic animals that animal shelters cannot accept might hint at the problem of overpopulation, but not necessarily; It could be because of various other reasons. Mentioning it lends the shelter a slightly negative image by making it seem like the shelter is trying to get rid of the dogs to accommodate more exotic animals, which would shift the focus of the claim to exotic animals.
- A statistic about the number of Americans who own dogs might be helpful in motivating people to adopt dogs, but doesn't provide information relevant to the claim regarding the overpopulation problem or its solution.
