Alternating shifts −4, +4, −4, +4 across positions QIOK : MMKO :: YAWC : ?

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:

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.

Final Answer:
UESG
