Understanding the Review Process

Key Rules:

• Initial review: Exactly one department member
• Chain rule: Each reviewer's supervisor must also review
• No extras: Only required reviewers participate
• Chain continues: Until reaching someone with no supervisor

Part 1: Maximum Reviewers with Laszlo

Possible Scenarios:

1. Laszlo initiates
   • Review chain: Laszlo → Davi → Adiliah
   • Total reviewers: 3
2. Saleema or Yarah initiates
   • Review chain: Saleema/Yarah → Laszlo → Davi → Adiliah
   • Total reviewers: 4

Critical Insight:
To maximize reviewers when Laszlo is included, start the chain from someone Laszlo supervises. This creates the longest possible chain through the hierarchy.

Maximum with Laszlo: 4 reviewers

Part 2: Maximum Reviewers with Adiliah

Key Constraint:
Adiliah has no supervisor, so she cannot initiate a review (no one would review after her).

Possible Chains Ending at Adiliah:

From Bao: Bao → Adiliah (2 reviewers)

From Davi: Davi → Adiliah (2 reviewers)

From Laszlo: Laszlo → Davi → Adiliah (3 reviewers)

From Saleema/Yarah: Saleema/Yarah → Laszlo → Davi → Adiliah (4 reviewers)

Critical Insight:
The longest chain to Adiliah starts from the bottom of the hierarchy (Saleema or Yarah), creating a 4-person review chain.

Maximum with Adiliah: 4 reviewers

Final Answer

• Laszlo among reviewers: Select 4
• Adiliah among reviewers: Select 4

Key Exam Strategy

For hierarchy-based TPA questions:

1. Visualize the structure immediately
2. Identify chain patterns - reviews flow upward
3. Find extremes logically - longest chains start from the bottom
4. Skip exhaustive testing - once you identify the pattern, apply it directly
