Zorluk: Çok zorMust Be True Questions

Any employee at the agency who has access to the central server must either have completed Level 4 security training or be directly supervised by a senior director. However, no employee who is directly supervised by a senior director is authorized to initiate external data transfers. Every member of the analytics team frequently initiates external data transfers, and most members of the analytics team have access to the central server.

If the statements above are true, which one of the following must also be true?

  1. Most members of the analytics team have completed Level 4 security training.Cevap
  2. B
    All employees who are authorized to initiate external data transfers are members of the analytics team.
  3. C
    Any employee who is not directly supervised by a senior director is authorized to initiate external data transfers.
  4. D
    All members of the analytics team have completed Level 4 security training.
  5. E
    Senior directors are not authorized to initiate external data transfers themselves.

Cevap

Most members of the analytics team have completed Level 4 security training.
The correct answer accurately synthesizes the overlapping premises. We know all analytics team members initiate transfers, meaning (by the contrapositive of the second rule) none of them are supervised by a senior director. We also know most analytics team members have central server access. Because anyone with server access MUST have either training or supervision, and we proved they lack supervision, this majority group MUST have the training.

Adım Adım Çözüm

1
Map the strict conditional statements provided in the stimulus.
1: Access Central Server → (Level 4 Training OR Supervised by Director). 2: Supervised by Director → CANNOT initiate external transfers. 3: Analytics Team Member → initiates external transfers.
Formalizing the rules is necessary to safely connect the logic without introducing assumptions.
2
Find the contrapositive of the second premise and chain it with the third premise.
Contrapositive of Premise 2: If an employee initiates external transfers, they are NOT supervised by a director. Chaining with Premise 3: Analytics Team Member → initiates transfers → NOT supervised by a director.
This establishes a definite negative fact about the entire analytics team: none of them have director supervision.
3
Evaluate the 'most' quantifier statement against the first premise.
The stimulus states: Most Analytics Team Members → have Access to Central Server. According to Premise 1, this majority must have either Level 4 Training OR Director Supervision.
This applies the mandatory 'either/or' requirement to a specific subset of employees (the majority of the analytics team).
4
Combine the deduction from Step 2 with the evaluation in Step 3.
Since NO analytics team member has Director Supervision (Step 2), the 'most' who have Central Server Access cannot rely on supervision to meet the requirement. Therefore, they MUST have Level 4 Training.
When an 'A OR B' condition is required, and 'B' is impossible, 'A' must be true.

Anahtar Kavram

Chaining conditional statements with contrapositives and applying them to quantifier logic (most) to force a deduction through a disjunction (or).
