Question

Based on the English alphabetical order, three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which letter-cluster pair DOES NOT belong to that group?
(Note: The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)

The correct answer is
RP - BJ

Logical Reasoning: Identifying the Odd Letter Cluster Pair

The task is to find the letter-cluster pair that deviates from a specific pattern shared by the others, based on the English alphabet sequence.

Analyzing Pair Relationships

We examine the relationship between the first letter of each pair and the second letter of the same pair, and how the first pair transforms into the second pair:

  • Option 1: PN - QO
    • P is followed by Q (P + 1 = Q).
    • N is followed by O (N + 1 = O).
    Pattern: Both letters advance by 1 position in the alphabet.
  • Option 3: MK - NL
    • M is followed by N (M + 1 = N).
    • K is followed by L (K + 1 = L).
    Pattern: Both letters advance by 1 position in the alphabet.
  • Option 4: FD - GE
    • F is followed by G (F + 1 = G).
    • D is followed by E (D + 1 = E).
    Pattern: Both letters advance by 1 position in the alphabet.

Identifying the Dissimilar Pair

Let's analyze the remaining option:

  • Option 2: RP - BJ
    • R to B: This is not a +1 shift (R is the 18th letter, B is the 2nd).
    • P to J: This is not a +1 shift (P is the 16th letter, J is the 10th).
    This pair does not follow the '+1' alphabetical shift pattern.

Conclusion

Options 1, 3, and 4 share a common logic where both letters in the cluster advance one step in the alphabetical sequence. Option 2 (RP - BJ) does not adhere to this logic, making it the odd one out.
