answer: #Person1# thinks the earliest shipment is too late and wants Mr. Black to have the fertilizers delivered before April. Mr.Black assures #Person1# that they will.
documents: #Person1#: Mr. Black, when is the earliest shipment you can make?
  #Person2#: In April or early May.
  #Person1#: I am afraid shipment by early May would be too late for us. Our customs formalities are quite complicated, and it takes time to distribute the goods to the farmers in our country. The fertilizers must be delivered before April, or else we can't be in time for the spring sowing.
  #Person2#: In that case, we will have to improve one month further on the time. Now is Jan. If the fertilizers should be shipped before the end of March, only 2 months are left. The time is too limited.
  #Person1#: You understand a timely delivery is very important to us.
  #Person2#: All right. You can rest assured that we will do everything possible to advance shipment. The fertilizers will be delivered before April.
