Speed ranking logic: given 'Mara runs faster than Gail' and 'Lily runs faster than Mara', evaluate the truth of 'Gail runs faster than Lily'

Given data

• M > G (Mara faster than Gail)
• L > M (Lily faster than Mara)

Concept/Approach (why this method)

Use strict order transitivity on 'faster than': L > M > G ⇒ L > G.

Step-by-Step deduction1) From L > M and M > G, deduce L > G.2) The statement claims G > L, which contradicts L > G.

Verification/Alternative

No equalities or ties are stated; 'faster than' is strict, so contradiction stands.

Common pitfalls

• Overlooking transitivity; assuming cyclical speed relations (not possible under strict 'faster than').
