Questions 10-14
A researcher is experimenting with varying arrangements of exactly six units that are electrical conductors—G, J, K, M, P, and S—in a loop containing eight positions, each capable of containing one conductor. In each arrangement, exactly two positions are empty. In devising arrangements, the researcher must obey the following restrictions:
G must be directly adjacent to J.
P must be directly adjacent to S.
M must be directly adjacent to S, on one side and to an empty position on the other.
A signal can be transferred from one conductor directly to another when the two conductors are directly adjacent to each other, and only then. A signal can be transferred either way around the loop, from one conductor to another, until it reaches an empty position. A signal cannot be transferred across an empty position.
10) If a signal can be transferred, either directly or indirectly, from J to K, it must be true that a signal can be transferred, either directly or indirectly, from
(A) G to K
(B) G to M
(C) J to M
(D) J to P
(E) J to S
11) If K is directly adjacent to P, any of the following could be true EXCEPT:
(A) G is directly adjacent to K.
(B) J is directly adjacent to K.
(C) J is directly adjacent to P.
(D) G is directly adjacent to an empty position.
(E) J is directly adjacent to an empty position.
12) If P is directly adjacent to an empty position, which of the following is the greatest number of conductors, including starting and ending conductors, that can be used in the transfer of a single signal?
(A) Two
(B) Three
(C) Four
(D) Five
(E) Six
13) If there is one conductor that is directly adjacent to both of the empty positions, that conductor must be
(A) J
(B) K
(C) M
(D) P
(E) S
14) If a signal can be transferred from G to S, any of the following conductors could be directly adjacent to an empty position EXCEPT
(A) G
(B) J
(C) K
(D) M
(E) P
