Sorting out how long the debate will last. Or when the debate will start

A: If a house is settling, it means that parts of the house are creaking or shifting due to gravity. It doesn't mean the house is falling down.

A: いいです！:)

A: It's ambiguous and could be either "opportunity to grow" or "challenge to grow and opportunity to grow".

I would read it as "I love the challenge, and I love the opportunity to grow" here, just because there are phrases like "I love a challenge". But it really could be read either way, and in my own writing I would probably rephrase it to avoid the ambiguity of meaning.

A: Being adjusted slightly downward by gravity.

A: × We’re settling in the new living environment here.
✓ We’re settling into our new living environment here.

living environmentは別に問題ないですが、"life"や"lifestyle"や"living situation"などの方が自然と思います。

A: It means to get used to being somewhere new. It's often used as an expression when someone moves away from home to say they are content with where they are now.
