Directions: Select the option that represents the correct order of the given words as they appear in a standard English dictionary.

2. Tariff

3. Tardy

4. Tarnish

5. Tariffed

The correct answer is 31254.

To arrange the given words in the sequence in which they appear in a standard English dictionary, we compare them letter by letter from left to right.

The given list of words is:
1. Target
2. Tariff
3. Tardy
4. Tarnish
5. Tariffed

Step 1: Compare the first three letters
All five words share the exact same first three letters: T-a-r. Therefore, we must compare the 4th letter of each word:

- Tardy (4th letter is d)
- Target (4th letter is g)
- Tariff (4th letter is i)
- Tariffed (4th letter is i)
- Tarnish (4th letter is n)

Step 2: Order words by the 4th letter
Comparing the 4th letters alphabetically (d, g, i, n):
- 'd' comes first, so 3. Tardy is 1st.
- 'g' comes next, so 1. Target is 2nd.
- 'i' comes next, which applies to both 2. Tariff and 5. Tariffed.
- 'n' comes last, so 4. Tarnish is 5th.

Step 3: Resolve tie between "Tariff" and "Tariffed"
Comparing 2. Tariff and 5. Tariffed:
"Tariff" consists of 6 letters, and "Tariffed" has the exact word "Tariff" as its prefix followed by additional letters. In dictionary ordering, a shorter word that forms the exact prefix of a longer word always appears first.
Therefore:
- 2. Tariff is 3rd.
- 5. Tariffed is 4th.

Step 4: Final Dictionary Order
Putting all the positions together in sequence:
1st: 3 (Tardy)
2nd: 1 (Target)
3rd: 2 (Tariff)
4th: 5 (Tariffed)
5th: 4 (Tarnish)

Hence, the correct dictionary order of the words is represented by the code 31254.
