The Municipal Transit Authority maintains the following operational regulations for municipal bus routes:

• Every bus route that operates along the North Ridge corridor is classified as a high-altitude transit line.
• Any transit line classified as a high-altitude transit line requires winterized traction control systems.
• No transit line that requires winterized traction control systems is authorized for solo-operator night shifts unless it maintains dedicated thermal battery preheating.
• Route 42 operates along the North Ridge corridor and is authorized for solo-operator night shifts.

If the statements above are true, which one of the following must be true on the basis of them?

  1. A
    Any transit line that maintains dedicated thermal battery preheating is authorized for solo-operator night shifts.
  2. B
    Every transit line operating within the municipal transit network requires winterized traction control systems.
  3. Route 42 maintains dedicated thermal battery preheating.Cevap
  4. D
    Maintaining dedicated thermal battery preheating is sufficient to classify a transit line as a high-altitude line.
  5. E
    Route 42 operates exclusively during night shifts along the North Ridge corridor.

Cevap

Route 42 maintains dedicated thermal battery preheating.
The conclusion that Route 42 maintains dedicated thermal battery preheating is logically guaranteed. Route 42 operates on the North Ridge corridor, which means it is a high-altitude line and therefore requires winterized traction control. Under the regulations, any line requiring winterized traction control cannot be authorized for solo-operator night shifts unless it maintains dedicated thermal battery preheating. Because Route 42 is authorized for those night shifts, it must maintain dedicated thermal battery preheating.

Adım Adım Çözüm

1
Map the conditional relationships established by the stimulus rules
North Ridge corridor → High-altitude transit line → Requires winterized traction control. (Requires winterized traction control AND Authorized for solo-operator night shifts) → Dedicated thermal battery preheating.
Establishing the chain of necessary conditions allows direct evaluation of specific cases.
2
Apply the factual premises regarding Route 42 to the conditional chain
Route 42 is on North Ridge → Route 42 is a high-altitude line → Route 42 requires winterized traction control.
Determines which properties Route 42 necessarily possesses based on its route.
3
Synthesize the traction control requirement with the authorization rule
Since Route 42 requires winterized traction control and is authorized for solo-operator night shifts, it must satisfy the necessary condition: maintaining dedicated thermal battery preheating.
Completes the deductive inference guaranteed by the premises.
