Step-by-step explanation:
Conditional zero is used when the outcome will always happen as a result of the action carried out. It is also used to talk about situations and facts that are always true.
In the above sentences, we discover that the action performed leads to a result on the basis of the action. e.g. in No. 8: If we leave now, we will be home in time to see the football match.
You will discover that if actually they leave immediately, they shall meet up with the football match because they will be home early.
