Ordering Words Alphabetically

The task is to arrange the given words in the order they would appear in an English dictionary.

The words are:

• 1: Pollution
• 2: Popular
• 3: Population
• 4: Pocket
• 5: Pool

Dictionary Ordering Principles

Words are ordered based on their alphabetical sequence, letter by letter, from left to right. If the initial letters match, we proceed to compare subsequent letters until a difference is found.

Step-by-Step Word Comparison

1. First Letter: All words begin with 'P'.
2. Second Letter: All words have 'o' as the second letter.
3. Third Letter Comparison:
   • Pocket (c)
   • Pollution (l)
   • Pool (o)
   • Popular (p)
   • Population (p)
   Based on the third letter (c, l, o, p, p), the order starts with 'Pocket' (4).
4. Comparing 'Pollution' and 'Pool':
   • Pollution (l)
   • Pool (o)
   'l' comes before 'o', so 'Pollution' (1) follows 'Pocket'. 'Pool' (5) comes after 'Pollution'.
5. Comparing 'Popular' and 'Population':
   • Popular (popular)
   • Population (population)
   The first six letters ('popul') are the same. Compare the seventh letter:
   • Popular (a)
   • Population (a)
   The seventh letters are also the same ('a'). Compare the eighth letter:
   • Popular (r)
   • Population (t)
   'r' comes before 't' alphabetically. Therefore, 'Popular' (2) comes before 'Population' (3).

Final Alphabetical Order

Combining these steps, the correct dictionary order is:

1. Pocket (4)
2. Pollution (1)
3. Pool (5)
4. Popular (2)
5. Population (3)

This corresponds to the sequence 4, 1, 5, 2, 3.

Correct Option Identification

The sequence 4, 1, 5, 2, 3 matches Option C.
