Can you give me a precious tip from the following two paragraph?
1. Less than a decade into the new millennium, the separation between art and ordinary life is diminishing. ... Art is not a phase of life apart from the work-a-day world, to which one may turn in moments of leisure or perhaps in the name of so-called "culture,' or in a spirit of worship.
2. Whatever the reason for such behavior, unbalanced conversations usually remind us that turn taking is a fundamental part of the give and take that we expect from others in our everyday interactions.
I think,in 1, the underlined 'which' represents 'phase' and in 2, the underlined 'that' represents 'part.'
I want to know if I am right or not in my reasoning.
And I also want to know if someone asks me, why can't it be 'life' in 1, and why can't it be 'the give and take' in 2, how can I explain?
