Arrange the following words in the order in which they occur in an English dictionary and select the correct sequence of roman numerals. i. Harmony ii. Harness iii. Honey iv. Harangue

Introduction / Context:
This question involves arranging four words starting with H A in dictionary order. The words Harmony, Harness, Honey, and Harangue share the same first two letters, which makes it necessary to compare further letters carefully. This type of reasoning question checks whether candidates can accurately apply alphabetical rules beyond just the first or second letter of each word.

Given Data / Assumptions:

• Words with roman numerals:
  • i. Harmony
  • ii. Harness
  • iii. Honey
  • iv. Harangue
• All four words begin with H A.
• We must follow standard dictionary ordering by comparing letters one by one.

Concept / Approach:
Since each word begins with H A, we move to the third letter for comparison. Harmony, Harness, and Harangue all continue with R (H A R), while Honey continues with N (H O N), so Honey will definitely come after all three HAR words. Among the words beginning with HAR, we then compare the fourth letters to decide the correct internal order, remembering that when comparing words with the same prefix, we move stepwise until we find the first point of difference.

Step-by-Step Solution:
Step 1: Group the words by their first three letters: Harangue (H A R A), Harmony (H A R M), Harness (H A R N), and Honey (H O N). Step 2: Since A in H A R comes before O in H O N, all HAR words must come before Honey in the dictionary. Step 3: Among the HAR words, compare the fourth letters: Harangue has A, Harmony has M, and Harness has N. Alphabetically, A comes before M and N, and M comes before N. Therefore, the order among these three is Harangue, Harmony, Harness. Step 4: Finally, place Honey at the end because it starts with H O, and O follows A in the alphabet. Thus, the full dictionary order is Harangue (iv), Harmony (i), Harness (ii), Honey (iii), giving iv, i, ii, iii.

Verification / Alternative check:
To verify, we can mentally list all words under the letter H: first those starting with H A, then those with H O. Within H A, words beginning with H A R precede any other H A combinations if present. Among H A R words, we look at the next letters A, M, and N, and confirm that A comes first, followed by M and then N. Honey, starting with H O, clearly comes last. Converting this back into roman numerals confirms iv, i, ii, iii as the correct answer.

Why Other Options Are Wrong:
Option A (iii, ii, i, iv) starts with Honey, which is incorrect because H O must come after H A in the alphabet. Option B (iv, i, iii, ii) places Honey before Harness, despite N after H O coming later than N after H A R in the ordering. Option C (iv, ii, i, iii) reverses Harmony and Harness, even though M comes before N. Option E (i, ii, iv, iii) begins with Harmony and then Harness, but places Harangue later, although Harangue has an earlier letter A at the fourth position compared to M and N.

Common Pitfalls:
Students sometimes place Honey too early because it is a common and easily recognised word, forgetting that H O follows H A. Another mistake is to line up the HAR words without carefully inspecting the fourth letter, relying only on the meanings or sounds of the words. A systematic approach where you compare each letter step by step helps avoid such intuitive but incorrect answers.

Final Answer:
The correct dictionary order is Harangue, Harmony, Harness, Honey which corresponds to the roman numeral sequence iv, i, ii, iii.
