Final answer:
Responses B and C are the most accurate in portraying the authors' viewpoints, with B highlighting the difference in perspective regarding the animals' enjoyment, and C noting the differing opinions on the benefits of zoos for animal conservation.
Step-by-step explanation:
Based on the provided excerpts and overall context, response B and response C most accurately represent the viewpoints of the authors regarding zoos. Response B suggests that while the first author finds visiting the zoo to be fun, the second author considers whether the animals share this sentiment. Response C represents the comparison between the first author, who believes zoos benefit animals, and the second author, who questions the efficacy of zoos in animal conservation efforts. Neither excerpt suggests that both authors believe zoos are the best way to see animals in their natural habitat, which eliminates response D. As for response A, it is not directly supported by the excerpts indicating the authors' viewpoints on zoos as educational tools; their stances are more complex and nuanced than this response indicates.
