To assess the impact of invasive species on ecosystems in Africa, Benis N. Egoh and colleagues reviewed government reports from those nations about how invasive species are undermining ecosystem services (aspects of the ecosystem on which residents depend). The services were sorted into three categories: provisioning (material resources from the ecosystem), regulating (natural processes such as cleaning the air or water), and cultural (nonmaterial benefits of ecosystems). Egoh and her team assert that countries in each region reported effects on provisioning services and that provisioning services represent the majority of the reported services.

A
Provisioning services represent 73% of the services reported for the West region and 33% of those for the Central region, but they represent 75% of the services reported overall.
(Choice B) None of the percentages shown for provisioning services are lower than 33%, and the overall percentage shown for provisioning services is 75%.
B
None of the percentages shown for provisioning services are lower than 33%, and the overall percentage shown for provisioning services is 75%.
(Choice C) Provisioning services are shown for each region, while no cultural services are shown for some regions.
C
Provisioning services are shown for each region, while no cultural services are shown for some regions.
(Choice D) The greatest percentage shown for provisioning services is 88% for the North region, and the least shown for provisioning services is 33% for the Central region.
D
The greatest percentage shown for provisioning services is 88% for the North region, and the least shown for provisioning services is 33% for the Central region.

which is the true correct answer a b c or d

Answer 1

To determine which choice best supports Egoh and colleagues' assertion that provisioning services represent the majority of reported services, we need to analyze the key points made in each choice in relation to that assertion.

Choice A: "Provisioning services represent 73% of the services reported for the West region and 33% of those for the Central region, but they represent 75% of the services reported overall."

• This choice supports the assertion as it shows provisioning services as a majority (75%) overall.

Choice B: "None of the percentages shown for provisioning services are lower than 33%, and the overall percentage shown for provisioning services is 75%."

• While this confirms that none are lower than 33% and states the overall percentage is 75%, it does not provide detailed percentages for each region, making it less direct in supporting the assertion.

Choice C: "Provisioning services are shown for each region, while no cultural services are shown for some regions."

• This choice mentions the presence of provisioning services in each region but does not address the majority aspect directly.

Choice D: "The greatest percentage shown for provisioning services is 88% for the North region, and the least shown for provisioning services is 33% for the Central region."

• This choice provides specific percentages for provisioning services but does not summarize the overall contribution to support the assertion explicitly.

Considering the requirement of supporting the assertion about provisioning services being the majority, Choice A is the best option as it explicitly states the percentages for specific regions and reaffirms that provisioning services represent 75% overall, which aligns with Egoh’s findings.

Thus, the correct answer is A.
