Question

Difficulty: MediumCause and Effect Reasoning

Consider the two situations presented below regarding the national logistics and travel infrastructure:

Situation X: Major commercial airlines have raised their domestic flight ticket prices by an average of 20% over the last fortnight.
Situation Y: The consortium of inter-state road freight operators has introduced a uniform 15% hike in their baseline transportation rates.

What is the most logical causal relationship between these two situations?

  1. A
    Situation X is the cause and Situation Y is its effect.
  2. B
    Situation Y is the cause and Situation X is its effect.
  3. C
    Both Situation X and Situation Y are independent causes.
  4. D
    Both Situation X and Situation Y are effects of independent causes.
  5. Both Situation X and Situation Y are effects of some common cause.Answer

Answer

Both situations are effects of a common underlying cause, such as a substantial increase in fuel prices.
Both situations describe simultaneous cost increases in different segments of the transportation sector. These segments (air travel and road freight) do not directly dictate each other's pricing. However, because both rely heavily on the same fundamental resource (fuel), a concurrent price hike strongly indicates they are both responding to a shared external trigger, such as an increase in crude oil prices. Therefore, both are effects of a common cause.

Step-by-Step Solution

1
Analyze the nature of the events described in both situations.
Both situations describe a significant increase in prices within the broader transportation and logistics sector (aviation and road freight) occurring in a similar timeframe.
Identifying the core theme helps determine if there is a direct link or a shared underlying macroeconomic factor.
2
Evaluate for a direct cause-and-effect relationship between the two situations.
Neither event directly causes the other; airline passenger prices and road freight tariffs cater to different operational needs and do not trigger each other directly.
This rules out options stating that one is the direct cause of the other.
3
Determine if the events are independent or linked by a common driver.
Since both modes of transport heavily rely on petroleum-based fuels, a simultaneous price hike in both strongly points to a shared external variable, such as a rise in global crude oil prices, making them parallel effects of a common cause.
This distinguishes between effects of independent causes and effects of a common cause.

Key Concept

Identifying common underlying macroeconomic variables that produce parallel effects across distinct sub-sectors.
