Quote:We can signify that something is concluded by saying 'that is' [whatever].
1.The choice of food is: Sausages; ham; cheese; eggs. That's it.
2. Tomorrow it will be sunny with scattered showers in the Manchester region.
That's the weather forecast.
3. It came off in my hand, honest. That's my story and I'm sticking to it.
1 & 3 aren't examples of concluded actions, C. In 1. the choice of food
