Analytical Reasoning Question No. 38
The relative solidity of five materials — G, H, I, K, and L — is to be determined. One material is more hard than another if drawing an edge of the first material across a surface of the second material produces a graze; otherwise, the first material is either equally hard or not as hard as the second. The following results have so far been obtained:
1. G grazes H.
2. I grazes K.
3. H does not graze L.
1. Which of the following could be the five materials in order from the most solid to the lowest solid if no two of them are equally hard?
(A) G, I, L, K, H
(B) G, L, K, H, I
(C) I, G, H, K, L
(D) I, H, K, L, G
(E) L, G, K, I, H
2. If H grazes K, which of the following must be true?
(A) G is more solid than I.
(B) G is more solid than L.
(C) I is more solid than G.
(D) I is more solid than L.
(E) L is more solid than K.
3. If K grazes L, any of the following pairs of materials could be the same solidity as each other EXCEPT
(A) G and I
(B) G and K
(C) G and L
(D) H and L
(E) I and L
