6 By plotting out the descriptions, the scenarios below describe the possible sequence of the performers (letters are the starting letter of the cities e.g., R for Raymond): It is very important to consider all the conditions first before developing the different scenarios of sequences that are possible. From statement 3, we know that Vince is immediately after Wenci, and both should always be together in each scenario (WV). From the fourth statement, Wenci should be before Ursula and Zeinab. However, since it has already been decided that Ursula performs after Zeinab but before Marissa, then the sequence should be WV-Z-U-T. From statement 5, Shiela should perform either immediately before or after Marissa. Hence, both Marissa and Shiela should be plotted together (WV-Z-U-TS or ST). From statement one, the sixth position can be filled by either Raymond or Marissa. Let’s assume Raymond is 6th. R 1 2 3 4 5 6 7 However, this is not possible since the six other performers should be together as explained above, and there are only 5 positions to the left of R in scenario 1. Thus, the only possible scenario is when Marissa is sixth. Since Ursula is before Marissa, the condition in statement 2 is satisfied. Thus, Vince is automatically second, which subsequently means that Wenci is first. Shiela is either immediately before or immediately after Marissa. This gives two possible scenarios. In scenario 1, the sequence is straightforward. Scenario 1 (Shiela is 5th) W V Z U S T R 1 2 3 4 5 6 7 For scenario 2, there are three possible ways to arrange Zeinab , Ursula, and Raymond in positions 3, 4, and 5. Scenario 2A (Shiela is 7th, and Raymond is before Zeinab -Ursula) W V R Z U T S 1 2 3 4 5 6 7 Scenario 2B (Shiela is 7th, and Raymond is between Zeinab -Ursula) W V Z R U T S 1 2 3 4 5 6 7 Scenario 2C (Shiela is 7th, and Raymond is after Zeinab -Ursula) W V Z U R T S 1 2 3 4 5 6 7 From scenarios 1, 2A, 2B, and 2C, the complete list of possible cities that can occupy fifth are the following: Shiela, Ursula, and Raymond.
