PrepTest 55, Section 1, Question 16
Mercotek carried out a study to compare the productivity of its night shift with that of its day shift. Every week the company's six crews�F, G, H, R, S, and T�were ranked from first (most productive) to sixth (least productive). There were no ties. For any given week, either G and T were the two night-shift crews or else S and H were�the four other crews were the day-shift crews for that week. The following relationships held for every week of the study:

F is more productive than G.
R is more productive than S.
R is more productive than T.
S is more productive than H.
G is more productive than T.
For any given week of the study, the ranking of all the crews is completely determined if which one of the following is true?
F ranks second that week.
G ranks fifth that week.
H ranks third that week.
R ranks third that week.
S ranks third that week.
