Dictionary Word Arrangement Explained

This question asks us to determine the correct sequence of the given words as they would appear in an English dictionary. This process is called arranging words in alphabetical order or lexicographical order.

List of Words and Their Numbers:

• 1. Enlightening
• 2. Ensure
• 3. Eighteen
• 4. Enormous
• 5. English

Step-by-Step Ordering Process:

We compare the words letter by letter starting from the first letter. If the first letters are the same, we move to the second letter, and so on, until we find a difference.

Step 1: Compare the First Letter

All the words start with 'E'. So, we need to look at the second letter.

Step 2: Compare the Second Letter

The second letters are:

• Enlightening: 'n'
• Ensure: 'n'
• Eighteen: 'i'
• Enormous: 'n'
• English: 'n'

The letter 'i' comes before 'n' in the alphabet. Therefore, 'Eighteen' (3) is the first word in the dictionary order.

Step 3: Compare Words Starting with 'En'

Now we compare the remaining words: Enlightening (1), Ensure (2), Enormous (4), and English (5). They all start with 'En'. We move to the third letter:

Comparing the third letters: 'g', 'l', 'o', 's'.

The alphabetical order of these letters is g, l, o, s.

This means the order of the words is:

• English (5) - because 'g' comes first.
• Enlightening (1) - because 'l' comes after 'g'.
• Enormous (4) - because 'o' comes after 'l'.
• Ensure (2) - because 's' comes last.

So, the order for these four words is 5, 1, 4, 2.

Step 4: Combine the Orders

Combining the first word 'Eighteen' (3) with the order of the rest (5, 1, 4, 2), we get the final dictionary arrangement:

3, 5, 1, 4, 2

Correct Option Identification:

The sequence 3, 5, 1, 4, 2 corresponds to the correct alphabetical order of the given words.
