Scheduling ---------- (source: http://www.pinkmonkey.com/studyguides/subjects/gre/contents.htm) Five educational films A, B, C, D, & E are to be shown to a group of students. The films are to be shown in a particular order, which conforms to the following conditions: A must be shown earlier than C. B must be shown earlier than D. E should not be the fifth film shown. 1. Which among the following is an acceptable order for showing the educational films? (A) A, C, B, D, E 2. In case C is shown earlier than E, which among the following will hold true? (A) B is the first film shown. 3. In case D is to be shown earlier than A, then for which among the following is there exactly one position from first through fifth in which it can be scheduled to be shown? (A) A 4. Which among the following is a pair of films that CANNOT both be shown earlier than E? (A) A and B 5. In case D and E are shown as far apart from each other as possible, which among the following would be true? (A) A is shown earlier than B. 6. In case B, D and E are to be shown one after the other in the given order, the two positions from first to fifth in which A could possibly be shown are: (A) first and second. 7. In case exactly one film is shown between A and C, and exactly one film is shown between B and D, which among the following will hold true? (A) B is the film shown between A and C.
