Passage Summary: Marta suggests looking for the most productive use of some land, which might not be walking trails; Arthur hears this and immediately defends the trails as if Marta had already rejected them.

Reasoning: Arthur responds to Marta's suggestion by insisting that the railway land is ideal for trails and that the proposal should not be dismissed.

Analysis: To identify how Arthur interpreted Marta, look at the gap between what she said and how he reacted. Marta was being cautious and open-minded, suggesting there *might* be better uses, but Arthur reacted as if she had flatly rejected the trail proposal. He interprets her 'maybe there's something better' as a 'no' to the trails. The correct answer will likely describe Arthur's view of Marta as being more opposed to the trails than her words actually suggest.
