Dictionary Word Order Explained

To find the correct dictionary order for the given words, we compare them letter by letter from the beginning. This process is also known as lexicographical ordering.

The words provided are:

• 1. Distinct
• 2. Discipline
• 3. Different
• 4. Distinguish
• 5. Disregard

Sorting the Words Alphabetically

First, we observe that all the words begin with the prefix 'Dis'. Therefore, we must look at the fourth letter of each word to start the sorting process:

• Discipline (2) - The fourth letter is 'c'.
• Disfferent (3) - The fourth letter is 'f'.
• Disregard (5) - The fourth letter is 'r'.
• Distinct (1) - The fourth letter is 't'.
• Distinguish (4) - The fourth letter is 't'.

We compare these fourth letters based on the standard English alphabet order: '$c$' comes first, followed by '$f$', then '$r$', and finally '$t$'.

Based on this comparison, we can establish the initial order:

1. Discipline (2) - because its fourth letter is 'c'.
2. Different (3) - because its fourth letter is 'f'.
3. Disregard (5) - because its fourth letter is 'r'.

The sequence determined so far is 2, 3, 5.

Ordering Remaining Words

The words Distinct (1) and Distinguish (4) both have 't' as their fourth letter. To determine their order relative to each other, we continue comparing subsequent letters.

Comparing Distinct (1) and Distinguish (4):

• The first six letters 'Distin' are identical in both words.
• Let's compare the seventh letters:
  • 1. Distinct: D i s t i n c t
  • 4. Distinguish: D i s t i n g u i s h
• The seventh letters are 'c' and 'g'. Since '$c$' comes before '$g$' in the alphabet, Distinct (1) comes before Distinguish (4).

Complete Dictionary Order

By combining the results from the previous steps, we get the complete dictionary order for all the words:

1. Discipline (2)
2. Different (3)
3. Disregard (5)
4. Distinct (1)
5. Distinguish (4)

The correct sequence of the numbers corresponding to this dictionary order is 2, 3, 5, 1, 4.

This sequence matches Option 3.
