Input:  Person1:       May I ask you a few questions about insurance ?  
 Person2:Yes .  
 Person1:        Now we've given a CIF Shanghai price for some steel plates . What insurance rate do you suggest we should get ?  
 Person2:Well . Obviously , you won ’ t want All Risks cover .  
 Person1:        Why not ?  
 Person2:Because they aren ’ t delicate goods and won ’ t likely be damaged on the voyage . FPA will be good enough .  
 Person1:        Then am I right in understanding that FPA doesn't cover partial loss for the nature of particular average .  
 Person2:That's right . On the other hand , a WA policy covers you against partial loss in all cases .  
 Person1:        Are there any other clauses in marine policies ?  
 Person2:Oh , lots of them . For instance , War Risks , TEND and SICC .  
 Person1:        Well , thank you very much for all that information . Could you give me a quotation for my consignment now ?  
 Person2:Are you going to make an offer today ?  
 Person1:        Yes . My customer is in urgent need of the steel plates .  
 Person2:Ok , I'll get this rate right away .  
 Person1:        Thank you .
