PASSAGE
The physicist posited that the anomaly was not a measurement error but rather a ______ feature of the quantum system, intrinsic to its very nature.
Which choice completes the text with the most logical and precise word or phrase?
A. superficial
B. transient
C. concomitant
D. inherent✓ Correct
Detailed Explanation
Something that is 'intrinsic to its very nature' is essential. 'Inherent' means existing in something as a permanent, essential, or characteristic attribute.
Key Evidence:
• "intrinsic to its very nature"
• "not a measurement error"
Why others are wrong: A (Superficial means on the surface.), B (Transient means temporary.), C (Concomitant means naturally accompanying, but inherent is a stronger fit for 'intrinsic nature'.).
