DIRECTIONS:
The following questions are based on a passage of or set of statements. Choose the best answer for the question.
Six commuter trains depart, one every hour on the hour. Of the six, three are express trains( the streamliner, the coast, and the flyer ) and three are local trains (the arrow, the beamer , and the zephyr ). Four commuters (Jackson,klien,landau, and morris ) each ride a different train. The following is always true:
The first train departs at 5 a.m. and the last train departs at 10 a.m.
Each train departs at a different hour, and the express trains depart only at odd-numbered hours.
The Zephyr departs earliest than the Coast.
If the Coast departs at 7 a.m. than the Streamliner departs at 5 a.m.
Klien's train departs at 7 a.m. Morris rides the Beamer, which departs at 10a.m.
Jackson's train departs before kliens's , and Landau's train departs after klien's.
