Understanding Dictionary Order Arrangement

The question asks us to arrange a given set of words in the sequence they would appear in a standard English dictionary. This process is based on alphabetical order, comparing the words letter by letter from left to right.

The given words are:

1. Linger
2. Large
3. Lamp
4. Lost
5. Long

Step-by-Step Dictionary Arrangement

We compare the words based on their letters, moving from the first letter to the next until the order is determined.

Step 1: Compare the first letter.

All the words begin with the letter 'L'. Since the first letter is the same for all words, we move to the second letter.

Step 2: Compare the second letter.

• Linger (i)
• Large (a)
• Lamp (a)
• Lost (o)
• Long (o)

Comparing the second letters (i, a, o), we know that 'a' comes before 'i' and 'o' in the alphabet. So, the words starting with 'La' (Large, Lamp) will come first. Next will be the word starting with 'Li' (Linger). Finally, the words starting with 'Lo' (Lost, Long) will come last.

Our partial order is now: (Lamp, Large), (Linger), (Long, Lost).

Step 3: Arrange words with the same second letter.

We need to arrange 'Large' and 'Lamp'. Both start with 'La'. We compare the third letter:

• Large (r)
• Lamp (m)

Comparing 'r' and 'm', 'm' comes before 'r' in the alphabet. Therefore, 'Lamp' comes before 'Large'.

The order for these two words is: Lamp, Large.

Next, we need to arrange 'Long' and 'Lost'. Both start with 'Lo'. We compare the third letter:

• Long (n)
• Lost (s)

Comparing 'n' and 's', 'n' comes before 's' in the alphabet. Therefore, 'Long' comes before 'Lost'.

The order for these two words is: Long, Lost.

Step 4: Combine the sorted groups.

Combining the sorted words based on our analysis:

1. Lamp (starts with 'La', 'm' before 'r' in Lamp/Large)
2. Large (starts with 'La')
3. Linger (starts with 'Li')
4. Long (starts with 'Lo', 'n' before 's' in Long/Lost)
5. Lost (starts with 'Lo')

So, the correct dictionary order is Lamp, Large, Linger, Long, Lost.

Mapping back to the original numbers:

• Lamp is word 3
• Large is word 2
• Linger is word 1
• Long is word 5
• Lost is word 4

The sequence of numbers is 3, 2, 1, 5, 4.

Let's check this against the provided options to find the correct sequence.

The dictionary order is Lamp (3), Large (2), Linger (1), Long (5), Lost (4). The sequence is 3, 2, 1, 5, 4.

Additional Information: Dictionary Skills

Arranging words in dictionary order is a basic skill used not only when using a physical dictionary but also in various sorting tasks, indexing, and database management. It is a common type of question in reasoning sections of competitive exams to test logical sequencing ability. Mastering this skill involves understanding the strict left-to-right comparison of letters and how to handle cases where prefixes are identical.

For example, if we had words like 'Apple', 'Apply', and 'Application', they would be sorted by comparing letters after 'Appl'. 'e' comes before 'i' and 'y'. 'i' comes before 'y'. So the order would be Apple, Application, Apply.
