Arrange the following words in correct dictionary order 1 Yangtze 2 Yakking 3 Yakuzas 4 Yobbery and 5 Yobbish.

Introduction / Context:
Questions on dictionary order or alphabetical order test a candidate's ability to compare words letter by letter, just as a dictionary does. This question gives five words Yangtze, Yakking, Yakuzas, Yobbery, and Yobbish, numbered from 1 to 5, and asks for the correct sequence in which they will appear in a standard English dictionary. Such problems check both careful observation and accurate application of alphabetical rules, which is very useful in verbal reasoning and aptitude sections of competitive exams.

Given Data / Assumptions:
- The words given are: 1 Yangtze, 2 Yakking, 3 Yakuzas, 4 Yobbery, and 5 Yobbish. - We assume standard English alphabetical ordering, comparing letters from left to right. - The options present different permutations of the numeric labels 1 to 5. - Exactly one sequence matches the true dictionary order.

Concept / Approach:
Dictionary order means that words are arranged according to the alphabetical ordering of their letters. We compare the first letter of each word; if there is a tie, we move to the second letter, then the third, and so on. In this set, all words start with the letter Y, so we must compare the second and later letters. Among words starting with Ya and Yo, those starting with Ya will come before those starting with Yo. Within words starting with Ya, we compare the third letter, and if necessary, the fourth letter. The same logic applies to words starting with Yo. By systematically applying this letter by letter comparison, we can derive the correct numeric sequence.

Step-by-Step Solution:
1. Write down the words with their numbers: 1 Yangtze, 2 Yakking, 3 Yakuzas, 4 Yobbery, 5 Yobbish. 2. Note that all words begin with Y, so go to the second letter: words 1, 2, and 3 begin with Ya, while 4 and 5 begin with Yo. 3. Words starting with Ya come before words starting with Yo, so among 1, 2, and 3 we must order them first. 4. Compare Yangtze, Yakking, and Yakuzas letter by letter: Ya is common, so look at the third letter. For Yangtze it is n, for Yakking and Yakuzas it is k. Since k comes before n, words with Yak come before Yangtze. 5. Now compare Yakking and Yakuzas: Ya and k are common, then the fourth letter is k in Yakking and u in Yakuzas. Since k comes before u, Yakking comes before Yakuzas. 6. Thus the order among these three words is 2 Yakking, 3 Yakuzas, 1 Yangtze. 7. Now compare the remaining words 4 Yobbery and 5 Yobbish. Both start with Yo and share yob as a starting pattern, so compare the next letters. After yob, Yobbery has b e r y and Yobbish has b i s h. The letter e comes before i, so Yobbery comes before Yobbish. 8. Combining both groups, the full dictionary order is 2 Yakking, 3 Yakuzas, 1 Yangtze, 4 Yobbery, 5 Yobbish, which corresponds to the numeric sequence 23145.

Verification / Alternative check:
As a quick verification, a candidate can mentally group words by their second letter: Ya words first, then Yo words. Within each group, they can check for any obvious alphabetical anomalies. For example, Yakking should come before Yakuzas because k is before u, and Yakuzas should come before Yangtze because k is before n. Similarly, Yobbery comes before Yobbish because e is before i. If this pairwise checking does not reveal any contradictions, the final sequence 23145 can be trusted. With practice, such comparisons become faster and more intuitive.

Why Other Options Are Wrong:
Option 24531 starts with word 2 but then jumps to word 4, placing a Yo word before all Ya words have been listed, which breaks dictionary order rules. Option 54231 begins with word 5 Yobbish, which starts with Yo, and therefore cannot appear before any Ya words like Yakking or Yangtze. Option 54321 places both Yo words before all Ya words, which is opposite to correct alphabetical ordering. Option 23415 incorrectly arranges the last two words, putting Yobbish before Yobbery even though e comes before i.

Common Pitfalls:
A frequent mistake is to compare only the first two letters and assume that any tie can be ignored, which can lead to confusion between Yangtze and Yakuzas or between Yobbery and Yobbish. Another issue is reading the numeric pattern too quickly and not checking whether words starting with Yo have been placed after all words starting with Ya. Some candidates also misread spellings, especially of less familiar words like Yakuzas or Yangtze. To avoid these pitfalls, it is important to carefully look at each letter in sequence and, if necessary, rewrite the words in a column to visually compare them, even when solving mentally.

Final Answer:
The correct dictionary order of the given words is represented by the sequence 23145.
