Arrange the following words in the order in which they would appear in a standard English dictionary. Use the numbers given with each word to indicate the correct sequence: 1. Feeble 2. From 3. Floor 4. Foam 5. Fluorescent.

Introduction / Context:
This question tests your understanding of dictionary order, also known as lexical or alphabetical order. You are given five English words with associated numbers and asked to determine the order in which they would appear in a typical English dictionary. Once you know the correct order, you must choose the matching numerical sequence from the given options. Such questions are common in verbal reasoning sections to check attention to spelling and alphabetical comparison of letters beyond the first character.

Given Data / Assumptions:

• Words and codes: 1. Feeble, 2. From, 3. Floor, 4. Foam, 5. Fluorescent.
• We assume standard English dictionary ordering.
• Letter comparison is case insensitive; we compare letters from left to right.
• We must output the correct sequence as a string of digits, such as 13542.

Concept / Approach:
To arrange words in dictionary order, compare them letter by letter from left to right. First compare the first letters. If they are the same, compare the second letters, and so on, until a difference is found. The word whose differing letter is alphabetically smaller comes first. When one word is a prefix of another, the shorter word comes first. Here, all words start with the letter F, so we must examine subsequent letters carefully to determine the exact ordering.

Step-by-Step Solution:
Step 1: All words begin with F, so we compare the second letters: Feeble (e), From (r), Floor (l), Foam (o), Fluorescent (l). Step 2: Alphabetically, e comes before l, o, and r, so Feeble (1) must come first. Step 3: Now compare words starting with Fl: Floor (Flo...) and Fluorescent (Flu...). Between 'o' and 'u', the letter o comes before u, so Floor (3) comes before Fluorescent (5). Step 4: Next, compare the remaining Fo... and Fr... words: Foam (Fo...) and From (Fr...). Since 'o' comes before 'r', Foam (4) comes before From (2), so From will be last. Step 5: The final dictionary order is: Feeble (1), Floor (3), Fluorescent (5), Foam (4), From (2), giving the code 13542.

Verification / Alternative check:
As a quick verification, you can imagine looking these words up in a physical dictionary. You would first scan for FE, then FL, then FO and FR words. Among FL words, you would see FLOOR before FLUORESCENT. Among FO and FR, you would reach FOAM before FROM. Writing them out and checking the second and third letters again confirms that 1, 3, 5, 4, 2 is the only sequence consistent with dictionary order.

Why Other Options Are Wrong:
Option 15342 places Foam (4) before Fluorescent (5), which is incorrect because all FL words must precede all FO words. Option 13524 swaps the last two words, suggesting Foam before Fluorescent, which again violates the FL versus FO ordering. Option 15324 and other incorrect codes similarly ignore the correct alphabetical relationships between Floor, Fluorescent, Foam and From. Only 13542 respects the exact dictionary sequence.

Common Pitfalls:
Students sometimes compare only the first two letters and overlook tie breaking using the third or later letters. Another error is to focus on the length of words rather than actual alphabetical order; dictionary order is based on sequence of letters, not the number of letters. To avoid mistakes, always write the initial three or four letters of each word in a column and compare them systematically until you find a difference.

Final Answer:
The correct dictionary order corresponds to the sequence 13542, so option 13542 is the right answer.
