Understanding the Analogy: Fan and Blades

The question asks us to find a word pair that shares the same relationship as the pair "Fan : Blades". This type of question is called a word analogy, which tests our ability to understand the relationship between two words and apply that relationship to other pairs of words.

Analyzing the Relationship: Fan : Blades

Let's look at the relationship between 'Fan' and 'Blades'. A fan is a device that moves air, and blades are the rotating parts that perform this function. Blades are essential components or parts that make up a fan and enable it to work. We can describe this relationship as a 'Whole : Essential Part' or 'Object : Functional Component'.

Evaluating the Options for Related Word Pair

Now, let's examine each option to see which pair has a similar relationship:

1. Bonnet : Car

   A bonnet is a part of a car, specifically the cover over the engine. It's a part of the whole (Car), but it's not the primary functional component that makes the car move or perform its main action (like the engine or wheels). The relationship is 'Whole : Part', but maybe not 'Essential Functional Part'.

2. Room : House

   A room is a part of a house. A house is made up of multiple rooms. The relationship is 'Whole : Part'. However, a room is more of a defined section or division of the house, rather than a single, repetitive component like blades on a fan.

3. Arc : Circle

   An arc is a part of the circumference of a circle. The relationship is 'Whole : Part (segment)'. Like the previous options, this is a whole-part relationship, but an arc isn't a component that makes the circle 'work' in a functional sense analogous to blades in a fan.

4. Book : Chapter

   A chapter is a part of a book. A book is typically divided into multiple chapters, which contain the main content. Chapters are essential sections that collectively form the book's narrative or information. This relationship is 'Whole : Essential Section/Component'. Chapters are foundational units of a book, much like blades are foundational units of a fan's operation.

Finding the Best Analogy

Comparing the relationships:

• Fan : Blades → Whole : Essential Functional Component/Subdivision
• Bonnet : Car → Whole : Non-essential Cover Part
• Room : House → Whole : Defined Section/Division
• Arc : Circle → Whole : Segment of Circumference
• Book : Chapter → Whole : Essential Section/Component

The relationship between 'Book' and 'Chapter' most closely matches the relationship between 'Fan' and 'Blades'. Both pairs represent a whole entity being made up of several essential, repetitive components or sections that together form the complete item and enable its purpose (a fan to move air, a book to convey information).

Conclusion

Based on the analysis of the relationships, the pair "Book : Chapter" shares the most similar relationship with "Fan : Blades".

Additional Information: Solving Word Analogies

Word analogies are common in reasoning tests. Here are some tips for solving them:

• Identify the relationship between the first pair of words. Be specific (e.g., not just 'part of', but 'essential functional part', 'container and content', 'cause and effect').
• Express the relationship as a sentence (e.g., "Blades are parts of a Fan").
• Test this sentence on each option pair. "A Chapter is a part of a Book".
• Look for the option pair that best fits the relationship you identified. Sometimes, multiple options might seem similar; choose the one with the most precise or closest match to the original pair's relationship.
• Common analogy types include: Part to Whole, Whole to Part, Synonym, Antonym, Cause and Effect, Worker and Tool, Object and Function, Category and Example, etc.
