1. There are five time slots for the appointments at 9:30, 10:00, 10:30, 11:00, and 11:30.

9:30 |
10:00 |
10:30 |
11:00 |
11:30 |

First, the conditions should be diagramed. Start with the most restrictive condition and build from there. This is condition #3; Eric must have the 11:30 appointment slot.

9:30 |
10:00 |
10:30 |
11:00 |
11:30 |

Eric |

The second most restrictive is condition #2; Sarah cannot have the 10:00 or 11:00 appointment slot. Since Eric is already in the 11:30 slot, this leaves two possible slots for Sarah.

9:30 |
10:00 |
10:30 |
11:00 |
11:30 |

Sarah | Eric |

9:30 |
10:00 |
10:30 |
11:00 |
11:30 |

Sarah | Eric |

Next we add condition #4; Molly's appointment slot is immediately before Nick's. If Sarah has the 10:30 appointment, then there is only one place Molly and Nick's appointments can be.

9:30 |
10:00 |
10:30 |
11:00 |
11:30 |

Molly | Nick | Sarah | Eric |

However, if Sarah has the 9:30 then there are two possible places for Molly and Nick's appointments.

9:30 |
10:00 |
10:30 |
11:00 |
11:30 |

Sarah | Molly | Nick | Eric |

9:30 |
10:00 |
10:30 |
11:00 |
11:30 |

Sarah | Molly | Nick | Eric |

Condition #1 does not figure into any of the diagrams since Katie is only included if one of the other patients cancels, so the only thing left is to fill in the blanks with Bill's appointment into the three final diagrams.

Diagram #1

9:30 |
10:00 |
10:30 |
11:00 |
11:30 |

Molly | Nick | Sarah | Bill | Eric |

Diagram #2

9:30 |
10:00 |
10:30 |
11:00 |
11:30 |

Sarah | Molly | Nick | Bill | Eric |

Diagram #3

9:30 |
10:00 |
10:30 |
11:00 |
11:30 |

Sarah | Bill | Molly | Nick | Eric |

**1) E.** Looking at the three diagrams, Nick can have an appointment at 10:00, 10:30, or 11:00. So 9:30 and 11:30 or E is the correct answer.

**2) D.** This is solved by simply comparing each choice to the diagrams until one matches. A is incorrect since Eric isn't in the 11:30 slot, B and E are incorrect since Sarah can't be in the 10:00 or 11:00 slots, and C is incorrect since Nick must come immediately after Molly. D is the correct answer as it matches the second diagram.

**3) B.** Since the question specifies that Sarah's appointment is at 10:30, the first diagram is the one to use. While each answer could be compared the diagram until one that doesn't match is found, the easier way is to notice that B and C are exact opposites and so one of them must be the correct answer. Looking at the first diagram, Nick's appointment comes before Sarah's making B false and thus the correct answer.

**4) C.** Condition #1 states that Katie only gets an appointment if one of the others cancels, so since Bill has canceled this means that is slot is open. Looking at the diagrams for where Bill's appointment is, this means that either 10:00 or 11:00 has opened up and that C is the correct answer.

**5) D.** Look at each of the three diagrams and find the one where Molly's appointment is at 10:00, which is the second diagram. In the second diagram Bill's appointment is at 11:00 making D the correct answer.

**6) E.** This one actually changes one of the conditions and requires a new diagram. Eric's appointment is moved from 11:30 to 11:00.

**~(MJ)**. Condition #2, Jack sits next to Olivia or Nick, but not both of them, translates into

**JO e/or JN**. Condition #3, Kimberly sits next to Nick, translates into

**KN**. And Condition #4, If Olivia sits next to Jack, then she doesn't sit next to Lee, translates into

**OJ -> ~(OL)**. So the symbol translations of the conditions for this problem are:

**~(MJ)**

JO e/or JN

KN

OJ -> ~(OL)

JO e/or JN

KN

OJ -> ~(OL)

**7) C.** Simply compare each answer choice to the conditions; A breaks JO e/or JN, B breaks KN, D breaks ~(MJ), and E breaks OJ -> ~(OL). Only C doesn't break any of the conditions making it the correct answer.

**8) A.** Start off by placing Jack and Kimberly into their spots at the table, the specific spots don't matter as long as they are next to each other. Next place Nick next to Kimberly to satisfy condition #3 - KN. Since condition #2, JO e/or JN, requires that either Olivia or Nick sits next to Jack and Nick is already placed at the table two seats away from Jack, place Olivia next to Jack. Condition #4, OJ -> ~(OL), prevents Lee from sitting next to Olivia since she is already sitting next to Jack, so place Lee next to Nick to leave a space between Olivia and Lee. And finally place Melissa in the only remaining empty space.

Now it's an easy matter of comparing each answer choice to the diagram and seeing that only the pair in choice A are seated next to each other.

**9) E.** There is no need to diagram this problem. Looking at the answer choices, it's immediately clear that E breaks condition #3, KN, and is thus the answer.

**10) D.** Condition #1, ~(MJ), eliminates B and C, and condition #2, JO e/or JN, eliminates E, leaving only A and D as possibilities. Lee is an option in both of those choices, so the only question is whether or not a diagram can be constructed in which Kimberly sits next to Jack without breaking any of the conditions.

**11) A.** This one requires a diagram before any answer choices can be eliminated. First, place Jack and Nick next to each other on the diagram and Kimberly on the other side of Nick due to condition #3 - KN. Lee must sit on the other side of Jack, since condition #1, ~(MJ), prevents Melissa from sitting there and condition #2, JO e/or JN, prevents Olivia from sitting there. Olivia and Melissa cannot be placed on the diagram as they could each go in either seat.

**12) C.** First place Olivia next to Nick on the diagram and Kimberly on the other side of Nick due to condition #3 - KN. Next Jack is placed next to Olivia due to condition #2 - JO e/or JN. Melissa cannot be placed next to Jack due to condition #1, ~(MJ), so Lee goes next to Jack and Melissa takes the other empty seat.

Now simply compare the diagram to the answer choices and only Olivia sits between Nick and Jack appears on the diagram making C the correct answer.
