Finding the Correct Dictionary Order

To arrange words in the correct dictionary order, we compare them letter by letter from left to right. When the letters are the same up to a certain point, we look at the next letter to determine the order. If one word runs out of letters and is a prefix of another word (e.g., 'apple' vs 'applepie'), the shorter word comes first.

Step-by-Step Comparison of Words

Let's list the given words with their corresponding numbers:

• 1. Circulate
• 2. Circuit
• 3. Citrus
• 4. Cinnamon
• 5. Circular
• 6. Citizen

Now, we compare these words letter by letter:

• All words start with 'C'.
• The second letter for all words is 'i'.
• Comparing the third letter:
  • Circulate
  • Circuit
  • Citrus
  • Cinnamon
  • Circular
  • Citizen
  The letters are 'r', 't', 'n'. In alphabetical order, 'n' comes first, then 'r', then 't'.

Grouping by the Third Letter:

• Group 1 (starts with 'Cin'): Cinnamon (4) - This word starts with 'Cin', while others start with 'Cir' or 'Cit'. So, 'Cinnamon' comes first.
• Group 2 (starts with 'Cir'): Circulate (1), Circuit (2), Circular (5)
• Group 3 (starts with 'Cit'): Citrus (3), Citizen (6)

Ordering within Group 2 ('Cir'):

Let's compare Circulate (1), Circuit (2), and Circular (5).

• All start with 'Circu'.
• Comparing the sixth letter:
  • Circulate
  • Circuit
  • Circular
  The letters are 'l' and 'i'. 'i' comes before 'l'. So, 'Circuit' (2) comes first in this group.
• Now compare Circulate (1) and Circular (5). Both start with 'Circula'.
• Comparing the eighth letter:
  • Circulate
  • Circular
  The letters are 't' and 'r'. 'r' comes before 't'. So, 'Circular' (5) comes before 'Circulate' (1).

The order for Group 2 is: Circuit (2), Circular (5), Circulate (1).

Ordering within Group 3 ('Cit'):

Let's compare Citrus (3) and Citizen (6).

• Both start with 'Cit'.
• Comparing the fourth letter:
  • Citrus
  • Citizen
  The letters are 'r' and 'i'. 'i' comes before 'r'. So, 'Citizen' (6) comes before 'Citrus' (3).

The order for Group 3 is: Citizen (6), Citrus (3).

Final Dictionary Order

Combining the groups in order:

1. Group 1: Cinnamon (4)
2. Group 2: Circuit (2), Circular (5), Circulate (1)
3. Group 3: Citizen (6), Citrus (3)

The complete dictionary order of the words is:

Cinnamon, Circuit, Circular, Circulate, Citizen, Citrus

The corresponding numbers in order are:

4, 2, 5, 1, 6, 3

This order matches option 4.
