Which source would be the best to support a claim about endangered Sumatran tigers in the Indonesian jungle?

To determine the best source to support a claim about endangered Sumatran tigers in the Indonesian jungle, we need to consider which option represents an expert in the specific field and is likely to provide unbiased information. A Greenpeace activist: While Greenpeace works on environmental issues, an activist's primary role is advocacy, which can introduce bias. Their statements might be aimed at promoting a cause rather than providing purely objective scientific data. A rainforest botanist (plant scientist): A botanist specializes in plants. While Sumatran tigers live in rainforests, a botanist's expertise is not directly related to animal populations, especially big cats. A timber company biologist: A biologist working for a timber company might have knowledge of the local ecosystem, but their employer's economic interests (timber harvesting) could create a conflict of interest or bias regarding claims about endangered species that might impact logging. A big cat biologist: This individual is a specialist in large feline species, which directly includes Sumatran tigers. Their expertise is precisely in the subject matter of the claim (endangered big cats). This aligns with the principle of using "experts in the field" as reliable sources. Therefore, a big cat biologist would be the most authoritative and relevant source for information on endangered Sumatran tigers. The final answer is a big cat biologist
