The answers would be as follows
1. contract
2. hourly
3. monthly
Step-by-step explanation:
The comparison between the work on a cruise ship and the work on Recreational parks is something that can be taken note of in here.
The cruise ships require the person to work unspecified number of hours most of the time as the work on the ship may get unpredictable sometimes.
This is also incomparable to recreational parks that have shifts where the hours can be computed.
So the cruises instead pay people on monthly payroll or simply n a project payroll while the parks can offer hourly wages.
