Arrange the following words in the same sequence in which they would appear in an English dictionary, and then choose the correct code: 1. Follicle 2. Folk 3. Follow 4. Foliage.

Introduction / Context:
This problem asks you to place related words beginning with FOL in dictionary order. Words like Follicle, Folk, Follow, and Foliage have very similar spellings, so you must be careful in comparing letters beyond the obvious common prefix.

Given Data / Assumptions:

• Words: 1. Follicle 2. Folk 3. Follow 4. Foliage.
• We must find the dictionary order and express it as a code using the numbers 1 to 4.
• Standard English alphabetical rules apply.

Concept / Approach:
All four words start with F O L, so basic dictionary order rules require us to:

• Compare the next letter after the common prefix.
• Choose the word whose next differing letter is earliest in the alphabet.
• If required, continue comparing further letters until the ordering is clear.

Step-by-Step Solution:
Step 1: Identify the common prefix. All four begin with F O L. Step 2: Look at the fourth letter for each. Foliage has I (F O L I), Folk has K (F O L K), Follicle has L (F O L L), Follow also has L (F O L L). Step 3: Order words by this fourth letter: I comes before K, and K comes before L. Therefore Foliage (4) comes first, followed by Folk (2). Follicle (1) and Follow (3) come later since they have L in this position. Step 4: Now compare Follicle and Follow. Both begin with F O L L. Check the fifth letter. Follicle has I (F O L L I), while Follow has O (F O L L O). Since I comes before O, Follicle (1) appears before Follow (3). Step 5: Combining all comparisons, the dictionary order is Foliage (4), Folk (2), Follicle (1), Follow (3), which corresponds to the code 4, 2, 1, 3.

Verification / Alternative check:
Reading the words in the final order Foliage, Folk, Follicle, Follow, you can confirm that they sound correctly alphabetised, since all I variants appear before K, and both I types appear before K and later O sequences.

Why Other Options Are Wrong:
Option 3, 4, 2, 1 places Follow at the beginning, which conflicts with the fact that O occurs later than I and K in the critical positions. Option 4, 3, 1, 2 misorders both the Folk entry and the two L based words Follicle and Follow. Option 2, 4, 3, 1 incorrectly starts with Folk and also puts Foliage and Follow in the wrong relative positions. Option 2, 1, 4, 3 places Folk before Foliage and does not respect the correct alphabetical comparison at the fourth letter.

Common Pitfalls:
Because the words share similar beginnings and contain repeated L letters, it is easy to assume an incorrect order based on familiarity or meaning. Some test takers may even focus solely on word length. Careful character by character comparison, especially at the first point of difference, is the only reliable strategy.

Final Answer:
The correct dictionary sequence is Foliage, Folk, Follicle, Follow, resulting in the code 4, 2, 1, 3.
