conversations.from: assistant
conversations.value: Half of the floors have different numbers of apartments. Half the number of floors is 12 floors / 2 = 6 floors.
  One half of the block consists of 6 floors * 6 apartments/floor = 36 apartments.
  And the other half consists of 6 floors * 5 apartments/floor = 30 apartments.
  There are 30 + 36 = 66 apartments on all floors in the block.
  All the apartments can therefore accommodate 66 apartments * 4 residents/apartment = 264 residents.
