Decode using a provided code–key table: Code row: L X P Z J Y Q M N B …; Key row: b a e s p r h i g t. Decode “Z B Y X M N Q B”.

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:

  • Code row: L X P Z J Y Q M N B …
  • Key row: b a e s p r h i g t
  • Coded word: Z B Y X M N Q B
  • Mapping is one-to-one and position-based across the two rows.


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:

Z→s, B→t, Y→r, X→a, M→i, N→g, Q→h, B→t.Combined: s t r a i g h t → “straight”.


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:

  • strength / height / struggle: Different letter patterns that do not match the decoded sequence.
  • None of these: Not applicable because “straight” is obtained directly by the table.


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:
straight
