Airplane Company, Inc. (ACI) and Sealant Factor, Inc. (SFI) agree that SFI will sell as much specialty sealant as ACI requires to manufacture commercial airplanes during the next 12 months at a price of $3.25 per gallon. For the first six months of the contract, ACI requires 200 gallons of sealant every month. In the fourth month, ACI orders 2,500 gallons. SFI only provides 200 gallons to ACI, and ACI sues for breach of contract. What evidence is least important to ACI's claim?
a) Whether ACI requested the 2,500 gallons in good faith.
b) Whether SFI subjectively intended that it would be required to sell 2,500 gallons in one month.
c) Whether 2,500 gallons is unreasonably disproportionate to the historical requirements of ACI.
d) Whether the contract between ACI and SFI included an estimate of how much sealant the parties expected would be required.
