Difficulty: Easy
Correct Answer: straight
Explanation:
Introduction / Context:
Here we are given a direct substitution table between a “code” alphabet (upper row) and a “key” alphabet (lower row). Each letter in the coded word maps to the corresponding letter directly beneath it. The task is to decode a sequence using this fixed table.
Given Data / Assumptions:
Concept / Approach:
Write a quick map: L→b, X→a, P→e, Z→s, J→p, Y→r, Q→h, M→i, N→g, B→t. Then translate each letter of the coded word in order.
Step-by-Step Solution:
Verification / Alternative check:
Ensure each letter used in the coded word appears in the mapping; they do. The decoded output is a common English word and appears among the options.
Why Other Options Are Wrong:
Common Pitfalls:
Accidentally reading the mapping upside down (key→code instead of code→key), or mismatching letters Z and B, which occur twice.
Final Answer:
