5. The woman's problem is that she wants to throw a party at her home but water supply will be shut off in her home at that the party day.
The man suggests two possible solutions to the problem. One suggestion is to hold the party somewhere else. Second suggestion is to use a bottled water. (Maybe purchasing the water is right)
I think that second suggestion is better for her. This is because it's almost impossible to find a place to accommodate such large groups. People usually do not want to host many people into their house. Also, even if she has to cut down on budget for decoration and food, she can still organize the party when she buy enough bottles of bottled water.
For these reasons, I would recommend the second option for her.
