find the mistake:
 

1- Do you think fatness or obesity is the reason of only having too much fat ?
2- A non-nuclear world is a dream that I font think can ever be seen .
3- Now that the disagreement has settled,I wish you'd remain friends forever.
4- Everyday Ola has to do the house jobs and look after five children,which is too many for her.

1- reason: result
2- seen: achieved
3- has settled: has been settled
4-many: much

Thank you for your effort
