Understanding Dictionary Order Arrangement

Arranging words in the order they appear in an English dictionary is also known as alphabetical order. To do this, we compare the words letter by letter, starting from the first letter.

We are given the following words with their corresponding numbers:

1. Sentence
2. Selector
3. Sentiment
4. Senile
5. Sincere

Let's compare these words letter by letter:

1. Compare the first letter: All words start with 'S'. This doesn't help us differentiate yet.
2. Compare the second letter: Four words (Sentence, Selector, Sentiment, Senile) start with 'Se'. One word (Sincere) starts with 'Si'. In the alphabet, 'e' comes before 'i'. Therefore, Sincere (5) will come after the other four words in the dictionary order. The preliminary order is (1, 2, 3, 4) followed by 5.
3. Compare the third letter for the first four words (Sentence, Selector, Sentiment, Senile):
   • Sentence: Sen**n**
   • Selector: Sel**l**
   • Sentiment: Sen**n**
   • Senile: Sen**n**
   In the alphabet, 'l' comes before 'n'. So, Selector (2) comes first among these four words. The order is now 2, (1, 3, 4), 5.
4. Compare the fourth letter for the remaining 'Sen' group (Sentence, Sentiment, Senile):
   • Sentence: Sent**t**
   • Sentiment: Sent**t**
   • Senile: Seni**i**
   In the alphabet, 'i' comes before 't'. So, Senile (4) comes first among these three words. The order is now 2, 4, (1, 3), 5.
5. Compare the fifth letter for the remaining 'Sent' group (Sentence, Sentiment):
   • Sentence: Sente**e**
   • Sentiment: Senti**i**
   In the alphabet, 'e' comes before 'i'. So, Sentence (1) comes first among these two words, and Sentiment (3) comes after it. The order is now 2, 4, 1, 3, 5.
6. Finally, Sincere (5) comes last as determined in step 2.

Combining these steps, the words in dictionary order are:

Selector (2), Senile (4), Sentence (1), Sentiment (3), Sincere (5)

The corresponding arrangement of the given numbers is 2, 4, 1, 3, 5.

This sequence matches one of the provided options.

Step-by-Step Arrangement

Here is a summary of the comparison process:

Based on the letter-by-letter comparison:

• Selector (2) is first (3rd letter 'l').
• Senile (4) is second (among 'Sen' group, 4th letter 'i').
• Sentence (1) is third (among 'Sent' group, 5th letter 'e').
• Sentiment (3) is fourth (among 'Sent' group, 5th letter 'i').
• Sincere (5) is fifth (2nd letter 'i').

The correct order of numbers is 2, 4, 1, 3, 5.

Additional Information: Dictionary Arrangement Tips

Here are some extra tips for arranging words in dictionary order:

• Always start comparing from the first letter.
• If the first letters are the same, move to the second letter, and so on.
• Continue comparing letters until you find a difference. The word with the letter that comes earlier in the alphabet is placed first.
• If one word runs out of letters and is a prefix of another word (e.g., 'cat' and 'catalog'), the shorter word comes first. However, this rule is not needed for the words in this question.
• Treat uppercase and lowercase letters the same if they were given mixed, although they are all capitalized here.

Mastering dictionary order is a fundamental skill for using dictionaries and sorting lists of words.
