Simple Caesar +1 mapping: PASS : QBTT :: FAIL : ?

Introduction / Context:
This is a straightforward Caesar cipher with a uniform shift of +1 applied to each letter. It is a foundational pattern used to test quick recognition of simple encoding rules in analogy questions.

Given Data / Assumptions:

• PASS → QBTT implies P→Q, A→B, S→T, S→T (each +1).
• We must encode FAIL using the same rule.

Concept / Approach:
Apply +1 to each character of FAIL independently and assemble the result. Remember to maintain letter order and use alphabetical wrap-around only if reaching Z (not needed here).

Step-by-Step Solution:

Verification / Alternative check:
Decoding by −1 returns FAIL from GBJM, confirming the mapping and computation are exact.

Why Other Options Are Wrong:

• GJBM/MBJG/MJBG: These options misplace letters or alter the order, violating the uniform +1 rule and the original letter sequence.

Common Pitfalls:
Reordering letters or accidentally applying varying shifts. Keep the process strictly position-wise and constant.

Final Answer:
GBJM
