Arrange the following words in the order in which they occur in an English dictionary and select the correct sequence of roman numerals. i. Next ii. Noisy iii. Neutral iv. Neither

Introduction / Context:
This question is another example of arranging similar looking words in dictionary order. The words Next, Noisy, Neutral, and Neither share the initial letter N but differ in subsequent letters. The test checks whether you can correctly apply alphabetical rules when the first letter is identical, and whether you can continue comparing letters until you find a difference that determines the order.

Given Data / Assumptions:

• Words with roman numerals:
  • i. Next
  • ii. Noisy
  • iii. Neutral
  • iv. Neither
• All words begin with N.
• We must follow strict English dictionary order.

Concept / Approach:
To arrange words beginning with the same letter, we look at the second letter, then the third, and so on, until the first difference appears. If two words share the first two letters, we consider the third letter, and continue in this way. In this case, three words start with N E while one starts with N O. Words with N E will therefore come before those starting with N O. Among the N E words, we then compare the letters after NE in a similar stepwise fashion.

Step-by-Step Solution:
Step 1: Separate the words by second letter. Next, Neutral, and Neither all start with N E, while Noisy starts with N O. Step 2: Since E comes before O, all words starting with N E will appear before Noisy in the dictionary. Step 3: Among the N E words, compare the third letters: Neither has N E I, Neutral has N E U, and Next has N E X. In alphabetical order, I comes before U, and U comes before X, so the order among these is Neither, Neutral, Next. Step 4: Finally, add Noisy at the end because it begins with N O, which follows N E alphabetically. Thus, the full dictionary order is Neither (iv), Neutral (iii), Next (i), Noisy (ii) which is iv, iii, i, ii.

Verification / Alternative check:
A quick verification is to mentally list the words after grouping by the first two letters: under NE come Neither, Neutral, Next; under NO comes Noisy. Then, check the third letters I, U, and X and confirm that I appears before U and U appears before X. Once that is done, placing Noisy at the end is straightforward because O comes after E. Mapping this sequence back to roman numerals yields iv, iii, i, ii, which is consistent with dictionary order.

Why Other Options Are Wrong:
Option A (iii, iv, i, ii) starts with Neutral even though Neither should be first among the NE group. Option B (i, iv, iii, ii) places Next first, ignoring that I in Neither comes before X in Next. Option C (ii, iii, i, iv) wrongly begins with Noisy, which must come last among these words because O follows E in the alphabet. Option E (iv, i, iii, ii) places Next before Neutral, even though the third letter U in Neutral comes before X in Next, which is not correct according to dictionary rules.

Common Pitfalls:
Students often read words quickly and compare only up to the second letter, leading to mistakes when several words share that same prefix. Others may try to order by familiarity or meaning, such as grouping similar sounding words together, which is not how dictionaries work. Always compare each letter systematically and remember that even a difference at the third or fourth position can completely change the alphabetical order.

Final Answer:
The correct dictionary order is Neither, Neutral, Next, Noisy which corresponds to the roman numeral sequence iv, iii, i, ii.
