  How to solve this?
conversations.from: assistant
conversations.value: First find out how many ounces of milk James had to begin with by multiplying the number of gallons by the number of ounces per gallon: 3 gallons * 128 ounces/gallon = 384 oz
  Now subtract the 13 ounces James drank from the initial amount of milk: 384 oz - 13 oz = 371 oz
