Question

The decrement after flight did not worsen with increasing flight .

• A. Scale
• B. Duration
• C. Height
• D. Condition

Hint:

Remember: While flight duration can cause fatigue, the decrement doesn't worsen significantly after a certain point, making "duration" the key factor.

Answer 1

The Correct Option is B

Step 1: Understanding the Context
This question relates to the effects of flight on the body, especially regarding fatigue or decrement (such as performance or endurance). While various factors can contribute to the decrement after a flight, it is common for duration of the flight to be a key factor influencing fatigue and recovery times.
Step 2: Analyzing the Options
- (A) Scale: This is a broad term and doesn't directly correlate with the decrement observed after flight.
- (B) Duration: The longer the flight duration, the more significant the decrement, but studies suggest that with increasing flight duration, the impact does not worsen significantly beyond a certain point. This is the correct choice.
- (C) Height: While altitude might have some effects (e.g., oxygen levels), this is not the direct cause of the decrement described here.
- (D) Condition: This term could refer to a variety of factors, but doesn't specifically relate to the change in decrement post-flight.
Step 3: Final Answer
Thus, the correct answer is (B) Duration, as it is the primary factor related to the decrease in performance post-flight.
