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 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.)
NJ-MP
SO-RV
PL-OR
LH-KN
SO-RV
Calculate the alphabetical forward distance or backward difference between the letters within each cluster pair. Look for consistent positional offsets.
Calculate the alphabetical forward distance or backward difference between the letters within each cluster pair. Look for consistent positional offsets.
Analyze Option A (NJ-MP)
N (14) - 4 = J (10), M (13) + 3 = P (16). The pattern is (-4, +3).
Analyze Option B (SO-RV)
S (19) - 4 = O (15), but R (18) + 4 = V (22). Here the second part is +4 instead of +3.
Analyze Option C (PL-OR)
P (16) - 4 = L (12), O (15) + 3 = R (18). The pattern is (-4, +3).
Analyze Option D (LH-KN)
L (12) - 4 = H (8), K (11) + 3 = N (14). The pattern is (-4, +3).
A: Follows the standard (-4, +3) alphabetical offset pattern, C: Follows the standard (-4, +3) alphabetical offset pattern, D: Follows the standard (-4, +3) alphabetical offset pattern.
B is correct because SO-RV follows a (-4, +4) pattern instead of the (-4, +3) pattern followed by all other options.
When analyzing letter pairs or clusters, always write down the numerical position (1 to 26) of each letter to quickly uncover arithmetic differences.
