SECTION 4 Questions 1-4 A manager who has exactly four projects—F, G, H, and I—to undertake in a given month has made the following determinations: F has priority over G. H has priority over I. If one project has priority over another, the project with priority must be started earlier than the other one. 1. Given only the determinations above, each of the following is a possible sequence in which the four projects could be started EXCEPT (A) F, G, H, I (B) F, H, G, I (C) F, H, I, G (D) H, F, I, G (E) H, G, F, I 2. If each of the projects takes equally long to complete, it must be true that (A) F is completed before H is completed (B) F is completed before I is completed (C) G is completed before H is completed (D) H is completed before G is completed (E) H is completed before I is completed 3. There would be exactly one order in which the four projects would have to be started if it were deter- mined that (A) F has priority over H (B) F has priority over I (C) H has priority over G (D) I has priority over F (E) I has priority over G 4. Which of the following pairs of additional determi- nations would NOT conflict with the priorities initially determined? (A) F has priority over H, and I has priority over F.
