Finding the Odd Word Pair

The question asks us to identify the word pair that is different from the others among the given options. We are presented with four pairs:

• Bag and Baggage
• Pen and Pencil
• Kith and Kin
• Bread and Butter

To find the odd one out, let's examine the nature of each pair.

Analyzing the Given Pairs

Let's look closely at what each pair represents:

1. Bag and Baggage: This is a common English idiom. It means taking all of one's possessions when leaving a place. It is used metaphorically.
2. Pen and Pencil: These are two types of writing instruments. While related in function, this pair is simply a listing of two distinct objects.
3. Kith and Kin: This is also a common English idiom. It refers to one's friends and relatives, or simply one's acquaintances and relations collectively.
4. Bread and Butter: This phrase is another well-known idiom. It typically refers to one's basic income or livelihood, or essential needs.

Identifying the Difference

Based on the analysis, we can see a clear distinction between the pairs:

• Bag and Baggage is an idiom.
• Kith and Kin is an idiom.
• Bread and Butter is an idiom.
• Pen and Pencil is a literal pairing of two items.

Three of the four pairs are established idiomatic expressions in the English language, carrying figurative meanings. The pair "Pen and Pencil" is not an idiom; it is a straightforward description listing two related, tangible items.

Therefore, the pair that is different, or the odd one out, is the one that is not an idiom.

Conclusion

The pair "Pen and Pencil" is the odd one out because it describes two objects literally, whereas "Bag and Baggage", "Kith and Kin", and "Bread and Butter" are idiomatic phrases used figuratively.
