Alphabet Analogy — Alternating Bidirectional Shifts AZBY : CXDW :: EVFU : ?

Question

Solve this multiple-choice question and choose the correct option.

Accepted Answer

Introduction / Context:This alphabet analogy uses alternating shifts: forward then backward repeatedly. Detecting the alternation in the first pair allows us to apply it to the second string precisely. Given Data / Assumptions: First mapping: AZBY → CXDW. Second mapping target: EVFU → ? Alphabet indexing: A=1 … Z=26. Concept / Approach:Compare each position in the first pair to see if the direction and magnitude of shifts alternate. Apply the same +/− pattern consistently to the second sequence. Step-by-Step Solution: A(1) → C(3): +2.Z(26) → X(24): −2.B(2) → D(4): +2.Y(25) → W(23): −2.So the rule is “+2, −2, +2, −2.”Apply to EVFU: E→G (+2), V→T (−2), F→H (+2), U→S (−2). Result = GTHS. Verification / Alternative check:Check reverse: subtracting and adding back restores EVFU, confirming the pattern’s correctness. Why Other Options Are Wrong: GHTS / GSTH / TGSH scramble the order or use incorrect intermediate letters, breaking the strict +2/−2 alternation. None of the above: Not applicable because GTHS fits perfectly. Common Pitfalls:Forgetting to alternate directions or miscounting positions when wrapping near Z. Here, no wrap-around occurs, simplifying the calculation. Final Answer:GTHS
