Phi-4

Judge: Correctly names the African wildcat (Felis lybica) as the closest relative and gives a well-organized, broad comparison. Mostly accurate, though a few claims are imprecise (e.g., wildcats having larger litters, wildcat coats being longer) and the domestication timeline is only vaguely indicated rather than dated.

Judge: Defines all three letters correctly, gives a valid AP example (Cassandra) and CP example (Spanner) plus a CA example, and accurately explains the partition-forces-a-choice tradeoff. Clear and well-structured; depth is solid though it could push slightly further on the concrete partition scenario.

Judge: Mentions laryngeal muscles and a frequency range (20-50 Hz, close enough to satisfy the constraint) and addresses the medical interest including bone healing. Clearly flags the ongoing debate and names the central pattern generator theory plus an alternative, satisfying the nuance requirement. Frequency cited is a bit narrow versus the typical 25-150 Hz.

Judge: Covers all four requested areas and correctly states Transformer attention is O(n2) and Mamba is linear. However it mischaracterizes Mamba's mechanism as 'selective attention' when Mamba's defining feature is a selective state space model that removes attention entirely, which is a meaningful imprecision. Description of the selective mechanism is present but weak.

Judge: Covers all three required countries with country-specific causes and consequences and discusses the IMF's role plus the controversy over austerity and high interest rates. Historically sound with good balance between IMF rationale and criticism. Some points are a touch generic but no significant errors.
