A.I. Explanation:

Correct Answer: ROOM 112

Why this is correct: The Room 112 entry names Ms. Rao. Casey wants to speak with her about Jamie’s work.

Tips: Keep the teacher with the correct room.

Why the other options are wrong:

• GYM OFFICE: The Gym Office meeting is with Mr. Bell, not Ms. Rao.
• LIBRARY: The Library appointment is with Ms. Chen.
• main entrance: The main entrance is a meeting point and route starting point, not Ms. Rao’s room.

Correct Answer: at 6:15 p.m.

Why this is correct: Mr. Bell’s appointment runs from six fifteen to six twenty-five. The question asks for its start, not its finish.

Tips: Distinguish the start from the end of an appointment.

Why the other options are wrong:

• at 6:10 p.m.: Six ten is Ms. Rao’s start time, not Mr. Bell’s.
• at 6:25 p.m.: Six twenty-five is Mr. Bell’s finish time.
• at 6:35 p.m.: Six thirty-five is the start of Ms. Chen’s later appointment.

Correct Answer: appointments cannot start late

Why this is correct: The footer says appointments cannot start late. Casey cannot finish the overlapping first meeting and then simply join the second late.

Tips: Check the rule before suggesting a late arrival.

Why the other options are wrong:

• families may join whenever they arrive: This contradicts the rule that appointments cannot start late.
• appointments always finish early: The schedule gives fixed slots and does not promise an early finish.
• teachers accept walk-ins between bookings: The guide gives booked appointments and does not offer walk-in time.

Correct Answer: Ms. Chen

Why this is correct: Ms. Chen is the later Library appointment, starting at six thirty-five after both early meetings.

Tips: Place the appointments in time order.

Why the other options are wrong:

• Ms. Rao: Casey will already have met Ms. Rao in the earlier slot.
• Mr. Bell: Mr. Bell’s meeting is one of the overlapping early appointments.
• Jamie: Jamie is the person whose work they are discussing, not a teacher in the guide.

Correct Answer: the west lift

Why this is correct: The Library row gives the west lift as the suggested route from the main entrance.

Tips: Use the route attached to the correct destination.

Why the other options are wrong:

• the east stairs: The east stairs lead to Room 112, not the Library.
• the ground corridor: The ground corridor route belongs to the Gym Office.
• the route to the Gym Office: The Library has its own west-lift route. The Gym Office route is different.

Correct Answer: Divide the overlapping meetings, then attend the last one together

Why this is correct: Casey asks Morgan to cover Mr. Bell while Casey sees Ms. Rao, then proposes attending Ms. Chen together.

Tips: Combine the separate parts of the proposed plan.

Why the other options are wrong:

• Cancel both early meetings and attend only the last one: Casey wants both early meetings covered, not cancelled.
• Ask every teacher to stay later than scheduled: The plan works within the booked times. Casey does not ask teachers to extend them.
• Have Morgan attend all three meetings alone: Casey plans to attend Ms. Rao’s meeting and the later meeting, not leave all three to Morgan.

Correct Answer: So each person can raise the other’s concerns while they are apart

Why this is correct: Exchanging questions lets each person represent the other’s concerns at the meeting they cannot both attend.

Tips: Think about why the writer offers to share information.

Why the other options are wrong:

• So the teachers can avoid discussing Jamie’s work: The point is to discuss their questions, not avoid Jamie’s work.
• So Morgan can select a different teacher: The teachers are already booked. Exchanging questions does not change the choice of teacher.
• So they can skip comparing what they learned: Casey still suggests comparing notes and discussing things at home.

Correct Answer: It is inconvenient but can be managed by cooperating

Why this is correct: Casey recognises the clash but suggests a practical shared plan. The email asks for cooperation rather than giving up.

Tips: Look at the proposed solution to understand the attitude.

Why the other options are wrong:

• It proves the teachers are unwilling to help: Casey blames the unnoticed clash, not the teachers’ willingness to help.
• It makes attending any of the meetings pointless: The email presents a way to benefit from all three meetings.
• It should be ignored because meetings can start late: Casey explicitly recognises that late starts are not allowed and changes the plan accordingly.
