GMAT Multi Source Reasoning : (MSR) Questions
The manager at the Gentle Wave Guesthouse just received three requests to reserve rooms for next week. The first request is for a room for one person for three nights, starting on Sunday, Monday, or Tuesday night. The second is for a room for three people for Thursday night only. The third is for a room for two people for two nights, Friday and Saturday. The manager will fulfill all three requests using the rooms listed on the Rooms tab and the Availability Calendar tab.
Any room that is available (that is, not already reserved) for the requested nights and whose maximum occupancy is equal to or greater than the number of people listed in the request will satisfy the request; no other rooms can be used to satisfy the request. For the two requests involving more than one person, sharing beds is an option, so the number of beds per room need not be equal to or greater than the number of people mentioned in the request.
For each of the nights, select Yes if the manager could fulfill the first reservation request by having it start that night, based on the information provided. Otherwise, select No.

|
| "The third is for a room for two people for two nights, Friday and Saturday" |

| "Any room that is available...and whose maximum occupancy is equal to or greater than the number of people listed in the request will satisfy the request" |

Summary: The guesthouse manager must fulfill three specific reservation requests for next week, with varying party sizes, durations, and date flexibility, following rules about availability and maximum occupancy.
Understanding Source B: Table - Room Inventory
| Information from Dataset | Analysis |
|---|---|
| "Moonlight Room: 1 bed, 2 max occupancy, ₩45,000" |
|
| "Seashell Room: 2 beds, 2 max occupancy, ₩40,000" |
|
| "Harbor Room: 2 beds, 3 max occupancy, ₩50,000" |
|
| "Starfish Room: 2 beds, 4 max occupancy, ₩75,000" |
|
| "Beach Room: 4 beds, 6 max occupancy, ₩100,000" |
|
Summary: The guesthouse offers five rooms ranging from ₩40,000 to ₩100,000 per night, with only Harbor, Starfish, and Beach rooms having sufficient capacity for the Thursday group request of 3 people.
Understanding Source C: Table - Availability Calendar
- Chart/Table Analysis:
- Inference: Shows room availability for next week (Sunday through Saturday)
- Inference: Each "x" indicates the room is already booked and unavailable that night
- Inference: Key patterns observed: Harbor and Moonlight rooms are heavily booked (4 nights each), while Starfish and Seashell have more availability (only 2 nights booked each)
- Specific Availability Findings:
- Beach Room: Unavailable Sun, Thu, Sat (available Mon, Tue, Wed, Fri)
- Harbor Room: Unavailable Sun, Mon, Thu, Fri (available Tue, Wed, Sat)
- Moonlight Room: Unavailable Mon, Tue, Wed, Fri (available Sun, Thu, Sat)
- Starfish Room: Unavailable Wed, Sat (available Sun, Mon, Tue, Thu, Fri)
- Seashell Room: Unavailable Tue, Thu (available Sun, Mon, Wed, Fri, Sat)
- Linkage to Source A & B: Harbor Room is unavailable Thursday, eliminating it for Request 2 despite having the minimum required capacity
- Linkage to Source A & B: For Request 3 (Fri-Sat), only rooms available both nights are Seashell (the cheapest option!)
- Linkage to Source A: For Request 1's flexible 3-night stay, multiple options exist depending on start date
Summary: The availability calendar reveals that despite capacity constraints from Source B, actual room options are further limited by existing bookings, with Seashell being the only option for the weekend request and only Starfish or Beach available for Thursday's group.
Overall Summary
- The Gentle Wave Guesthouse must fulfill three new reservation requests within a complex puzzle of room capacities and existing bookings
- The Thursday group request (3 people) can only be accommodated in Starfish or Beach rooms, as Harbor Room lacks Thursday availability
- The weekend couple must stay in Seashell Room - the only room available both Friday and Saturday
- The single traveler's flexible dates provide multiple options for their 3-night stay
- Despite the constraints, all three requests can be successfully fulfilled by matching capacity requirements with availability windows
Question Analysis
The question asks us to determine, for each possible starting night (Sunday, Monday, Tuesday), whether the manager can book a room for 1 person for 3 consecutive nights starting on that night.
Key Constraints:
- Must find availability for 3 consecutive nights starting on the specified day
- Room capacity must allow at least 1 person (all rooms qualify)
- No existing booking conflicts during those 3 nights
Answer Type Required: Yes/No evaluation per start night
Connecting to Our Analysis
The analysis includes room availability each night and their booking status, plus the first reservation request conditions. We can answer from the analysis alone because availability and booking data directly determine feasibility.
Extracting Relevant Findings
We need to check each potential 3-night booking window against the rooms' availability and booking status. A single person for 3 consecutive nights starting Sunday, Monday, or Tuesday requires that at least one room must be available without bookings for the entire 3-night period for that start night.
Sunday Start Analysis (Sun-Mon-Tue)
Is there a room available all three nights? The Starfish Room is free Sunday, Monday, and Tuesday, meeting the 3 consecutive nights requirement.
Result: YES - Starfish Room available for Sunday start
Monday Start Analysis (Mon-Tue-Wed)
Is there a room available all three nights? The Beach Room is free Monday, Tuesday, and Wednesday, meeting the 3 consecutive nights requirement.
Result: YES - Beach Room available for Monday start
Tuesday Start Analysis (Tue-Wed-Thu)
Is there a room available all three nights? No room is free all three nights Tuesday, Wednesday, and Thursday. All rooms have bookings conflicting in this window.
Result: NO - No room available for Tuesday start
Individual Statement/Option Evaluations
Statement 1 Evaluation
Evaluating the option "Yes":
- Criterion: Whether "Yes" represents the correct response pattern for all three starting nights
- Evidence from Analysis: Sunday start = Yes (Starfish Room available), Monday start = Yes (Beach Room available), Tuesday start = No (no rooms available)
- Assessment: The pattern shows two "Yes" responses and one "No" response, not all "Yes"
- Result: Incorrect - "Yes" does not represent the complete answer pattern
Statement 2 Evaluation
Evaluating the option "No":
- Criterion: Whether "No" represents the correct response pattern for all three starting nights
- Evidence from Analysis: Sunday start = Yes (Starfish Room available), Monday start = Yes (Beach Room available), Tuesday start = No (no rooms available)
- Assessment: The pattern shows two "Yes" responses and one "No" response, not all "No"
- Result: Incorrect - "No" does not represent the complete answer pattern
Systematic Checking
Confirmed availability status of each room for each 3-night period:
- Sunday start: Starfish Room available all 3 nights
- Monday start: Beach Room available all 3 nights
- Tuesday start: No rooms available all 3 nights
Final Answer
Based on the analysis, the complete answer pattern is: Sunday night: Yes, Monday night: Yes, Tuesday night: No. Neither "Yes" alone nor "No" alone represents this mixed pattern correctly.
- Statement 1: No
- Statement 2: No
