Answer: D

Explanation:

The passage highlights the Elkinsville Ecological Society's opposition to the proposed expansion due to concerns about its environmental impact, suggesting that they have likely conducted studies to evaluate these effects.

A) The Elkinsville Ecological Society will continue to oppose the northern expansion of the interstate.

This statement is plausible given the Society's concerns about environmental impact; however, the passage does not provide direct evidence about their future actions or intentions, making it unsupported.

B) Politicians in Elkinsville will win their efforts to approve the northern expansion of the interstate highway.

The passage does not indicate the outcome of political efforts regarding the expansion. It only mentions politicians' claims about benefits, without any evidence that they will succeed in their approval efforts.

C) There are no Elkinsville Ecological Society members among the city's politicians.

The passage does not address the composition of the city's politicians or any affiliations with the Elkinsville Ecological Society, leaving this statement unsupported.

D) A detailed environmental study of the northern expansion of the interstate has been conducted by the Elkinsville Ecological Society.

This statement is supported by the passage, which implies that the Elkinsville Ecological Society is analyzing the environmental implications of the proposed expansion, aligning with their opposition to the project.

Conclusion

The correct answer, D, is supported by the context of the passage, which indicates the Elkinsville Ecological Society's concern for environmental impacts, suggesting that they have likely conducted studies related to the expansion. The other options lack direct evidence or are not addressed in the passage, making them incorrect.
