NO. 4-2 SECTION 5
Questions 1-6
The consumer complaint department of a firm employs exactly six people who answer letters: G, H, I, J, K, and L. Every complaint letter received by the department is classified as either red or blue. The following procedures for answering the letters are used:
Red letters are given first to G or H. Blue letters are given first to any one of the following G, J, or I.
If a letter raises a problem that cannot be resolved by the person to whom it is given, it must be forwarded until it reaches someone who can resolve the problem and answer the letter. A letter must be forwarded as follows:
By G to I if the letter is red, but to J if the letter is blue;
By H to either G or I;
By I to J if the letter is red, but to K if the letter is blue;
By J to either I or K whether the letter is red or blue;
By K to L whether the letter is red or blue; L answers every letter given to him.
1. Any of the following can be true EXCEPT:
(A) G forwards a red letter to I.
(B) H forwards
