Understanding the Analogy: Teeth and Toothpaste

The question asks us to identify a pair of words that shares the same relationship as 'Teeth ∶ Toothpaste'. To solve this, we first need to understand the relationship between the given pair.

The relationship between Teeth and Toothpaste is one of cleaning and maintenance. Toothpaste is a substance used to clean teeth and maintain oral hygiene.

Analyzing the Options

Now, let's examine each option to see which pair exhibits a similar cleaning or maintenance relationship:

1. Face ∶ Powder: Powder is typically applied to the face for purposes like makeup, absorbing oil, or setting foundation. It's not primarily used for cleaning the face. So, this relationship is different from Teeth ∶ Toothpaste.
2. Button ∶ Jeans: A button is a fastening device that is a part of a pair of jeans. This is a part-to-whole or component relationship, not a cleaning or maintenance relationship. So, this pair does not match the original analogy.
3. Hair ∶ Shampoo: Shampoo is a product specifically designed to clean hair and the scalp. Just as toothpaste is used to clean teeth, shampoo is used to clean hair. This relationship of cleaning and maintenance is very similar to the relationship between Teeth and Toothpaste.
4. Foam ∶ Soap: Foam is a byproduct of soap when it is mixed with water and agitated. It's a form that soap takes when being used, not something used to clean soap itself, nor is soap used to clean foam. This relationship is different.

Identifying the Matching Relationship

Comparing the options, the pair 'Hair ∶ Shampoo' most closely matches the relationship of 'Teeth ∶ Toothpaste'. In both cases, the second word is a cleaning agent used for the first word.

Let's summarise the relationships:

• Teeth ∶ Toothpaste: Toothpaste cleans teeth.
• Face ∶ Powder: Powder is applied on the face (often for aesthetics/oil absorption, not cleaning).
• Button ∶ Jeans: Button is a part of jeans.
• Hair ∶ Shampoo: Shampoo cleans hair.
• Foam ∶ Soap: Foam is produced by soap.

Based on this analysis, the pair 'Hair ∶ Shampoo' shares the same relationship as 'Teeth ∶ Toothpaste'.

Conclusion

The pair 'Hair ∶ Shampoo' shares the same cleaning/maintenance relationship as 'Teeth ∶ Toothpaste'.
