I'd like to know if the following statements are possible.Thank you.

1) I wait fifteen minutes for my mum to arrive and drive me home.
2) I return home by bus.
3) He worked three hours overtime last Saturday. He was on overtime last Saturday.
4)He is on the dole and receives 400 Euros unemployment benefit from the state. He can' provide for his family any more.

All looks fine except for a spelling error in the last sentence. Do you see it?

Sure! I can help you with that. Let's evaluate each statement individually:

1) "I wait fifteen minutes for my mum to arrive and drive me home."
To determine the possibility of this statement, you would need to consider your specific circumstances. Ask yourself if it is common for your mum to pick you up and if she is usually able to do so within fifteen minutes. If the answer is yes, then this statement would be possible.

2) "I return home by bus."
To determine the possibility of this statement, you would need to assess the availability and accessibility of buses in your area. If there is a bus route that reaches your destination and you have the means to pay for the bus fare, then this statement would be possible.

3) "He worked three hours overtime last Saturday. He was on overtime last Saturday."
To verify the possibility of these statements, you would need to know the individual's work schedule and if overtime shifts are common at their place of employment. If the person typically has the option to work overtime and they did work three extra hours last Saturday, then both statements would be possible.

4) "He is on the dole and receives 400 Euros unemployment benefit from the state. He can't provide for his family anymore."
To assess the possibility of these statements, you would need to ascertain the individual's employment status and their financial situation. If the person is currently unemployed and receiving unemployment benefits, and if their financial situation is dire to the point where they can't provide for their family, then both statements would be possible.

In summary, determining the possibility of these statements requires a careful evaluation of the specific circumstances and information regarding the individuals involved.
