## Task 2 - 170512

Three pioneers who meet at a riddle camp are known for the following:

(1) Their first names are Frank, Gerd, and Harald.

(2) Their last names are Schulze, Müller, and Krause.

(3) Frank does not have the last name Krause.

(4) Gerd's father is an officer in the NVA.

(5) Gerd attends the 6th grade, the pioneer with the last name Krause goes to the 7th grade.

(6) The father of the pioneer with the last name Schulze works as a turner.

What are the full names of these three pioneers?
Since Frank does not have the last name Krause due to (3) and Gerd does not have it due to (5), Harald's last name is Krause. Gerd cannot have the last name Schulze according to conditions (4) and (6). Therefore, Gerd's last name is Müller. This means Frank's last name is Schulze.

That is, the names are Frank Schulze, Gerd Müller, Harald Krause.
