Directions:

Place these words in the order they would appear in an English dictionary.

1. Call
2. Callous
3. Caller
4. Calling
5. Calm

Correct Option: 1, 3, 4, 2, 5

To arrange the given words in dictionary (alphabetical) order, we compare the letters of each word from left to right step-by-step:

Given words:
1. Call
2. Callous
3. Caller
4. Calling
5. Calm

Step 1: Compare the initial letters of each word.
- All five words start with the prefix "Cal".
- Words 1, 2, 3, and 4 have 'l' as their fourth letter ("Call...").
- Word 5 has 'm' as its fourth letter ("Calm").
Since 'l' comes before 'm' in the English alphabet, Calm (5) must appear last among all five words.

Step 2: Order the words starting with "Call" (1, 2, 3, and 4).
- 1. Call: This is a 4-letter word. Since it forms the complete root/prefix of the other three words ("Caller", "Calling", "Callous"), a shorter base word always comes before any longer word built upon it. Thus, Call (1) comes first.
- Now, compare the 5th letter of the remaining three words:
- 3. Caller: 5th letter is 'e'
- 4. Calling: 5th letter is 'i'
- 2. Callous: 5th letter is 'o'
Alphabetically, the 5th letters follow the order: 'e' → 'i' → 'o'.
Therefore, their relative order is Caller (3) → Calling (4) → Callous (2).

Step 3: Combine all words in final sequence.
1. Call (1)
2. Caller (3)
3. Calling (4)
4. Callous (2)
5. Calm (5)

Thus, the correct dictionary order of the words is represented by the sequence 1, 3, 4, 2, 5.
