@slsadiq594 the answer is saying they took the teeth, moved around, then dumped them all in one spot. So it proves that they didn't live there year round. But I feel like they're expecting us to know that "using them in religious rituals" means they were moving off the land to do so. Nowhere in the answer does it allude to them leaving and coming back

@Nela I think you have the right "necessary" thinking but in this stimulus, we can't conclude that rocks are the only thing that could make this garden harmonious with nature. The stimulus doesn't say a garden needs to have rocks in order for the garden to achieve harmony with nature. Instead, it's imitation that is necessary to achieve harmony. So you have the right finding-what-is-necessary approach, and you know what part of the conclusion you need to prove, but you didn't pick the correct part of the argument
