Classification – Semantics of spreading vs redirecting: three words relate to spreading/thinning or spread description; one primarily means turning aside/entertainment. Find the odd one out. Options: Distribution, Dispersion, Diversion, Dilution.

Introduction / Context:
Word-classification items often hinge on fine semantic fields. Here, three terms concern spreading, thinning, or the statistical description of spread; one centers on rerouting or entertainment, not spreading.

Given Data / Assumptions:

• Distribution: allocation/arrangement across recipients or space; also a statistical term describing how values are spread.
• Dispersion: the extent or process of spreading out (physical/chemical/statistical contexts).
• Dilution: making a solution weaker by increasing solvent—effectively thinning/spreading solute concentration.
• Diversion: redirecting to a different course; also amusement/entertainment.

Concept / Approach:
Cluster words by the core idea “spread/thin.” Distribution, dispersion, and dilution align with this concept; diversion does not.

Step-by-Step Solution:
Distribution → spread/allocation semantics.Dispersion → spread-out process/extent.Dilution → thinning a mixture (lowering concentration).Diversion → rerouting/entertainment; not “spread.”

Verification / Alternative check:
Check dictionary senses: only “diversion” lacks the spreading/thinning core.

Why Other Options Are Wrong:
Distribution/Dispersion/Dilution: Each explicitly involves spreading or its effect.

Common Pitfalls:
Equating “distribution” solely with logistics; it also names a statistical spread, reinforcing the grouping.

Final Answer:
Diversion
