Answer
Correct Answer: UESG
Explanation
Introduction / Context:Some analogies use alternating positional shifts. Here, the pattern from the first pair reveals a −4, +4, −4, +4 sequence. We must apply it to the new source word.
Given Data / Assumptions:
- QIOK → MMKO.
- We work with A=1 … Z=26 and wrap-around.
- Goal: YAWC → ?
Concept / Approach:Compute the displacement on each position for the known pair, ensuring an alternating pattern, then replicate it on the new word.
Step-by-Step Solution:
Q→M: −4; I→M: +4; O→K: −4; K→O: +4.Therefore pattern is [−4, +4, −4, +4].Apply to YAWC:Y→U (−4), A→E (+4), W→S (−4), C→G (+4).Assembled result: UESG.Verification / Alternative check:Apply the inverse [+4, −4, +4, −4] to UESG; it returns YAWC. This confirms correctness.
Why Other Options Are Wrong:
- USGA/SUEG/VUES: Letters are permuted or shifted inconsistently, breaking the alternating rule.
Common Pitfalls:Assuming a uniform shift; forgetting to alternate direction by position; ignoring wrapping when subtracting from A or adding beyond Z.
