In this analogy, Book is related to Pages as a whole to its parts; choose the option that shows the same relationship for a Continent: Book : Pages :: Continent : ?

Introduction / Context:
This question examines your understanding of whole part relationships in general knowledge. A book is made up of many pages, which are its constituent parts. Similarly, a continent is a large geographic entity made up of several smaller political units. Recognising such hierarchical relationships is an important skill in verbal reasoning and everyday thinking.

Given Data / Assumptions:

• A book consists of multiple pages bound together.
• A continent is a large landmass on Earth.
• The options present different things that might be associated with a continent, such as water, forest, countries and land.
• We assume common geographical understanding, where continents are groupings of countries.

Concept / Approach:
In the analogy Book : Pages, the first term is a complete object and the second term lists the smaller units that combine to form that object. The correct analogy for Continent must follow the same pattern: a continent should be related to its main constituent political units. We therefore look for the option that represents what continents are composed of in political and geographical terms, not just what they contain physically.

Step-by-Step Solution:
Step 1: Identify the relation in Book : Pages. A single book is made up of many pages.Step 2: Translate this into a general pattern: whole object : smaller units that together form the whole.Step 3: Consider Continent. A continent is a very large landmass that contains several countries.Step 4: Examine option C, Countries. Continents such as Asia, Europe or Africa are composed of many countries, so this matches the whole to parts relationship.Step 5: Evaluate other options briefly. Water and forest are physical features found on or around continents, but they are not the basic political units of a continent.Step 6: Land describes the physical nature of a continent, not its subdivision into units.Step 7: Therefore, the only option that correctly mirrors the structure of the first pair is Countries.

Verification / Alternative check:
We can restate the analogy in words: A book consists of pages just as a continent consists of countries. This makes clear logical sense and follows standard geographic and political terminology. None of the other choices allow such a natural complete sentence, which confirms the correctness of the selected option.

Why Other Options Are Wrong:
Option A, Water, is something that may surround or be found on parts of a continent, but continents themselves are not defined as being made of water. Option B, Forest, is a type of vegetation that can cover some areas within a continent but again is not a structural unit. Option D, Land, repeats the idea that a continent is land, but does not break it into smaller units the way pages do for a book. Hence these options do not follow the whole part framework that the analogy demands.

Common Pitfalls:
Candidates sometimes focus only on simple association instead of the precise relationship. For example, they might think of continents and land together and choose Land, ignoring that pages are not just associated with a book but are its building units. It is important to ask, "What is the continent composed of in a political or geographic sense?" rather than simply "What do I think of when I hear continent."

Final Answer:
The correct completion of the analogy is Countries, so option C is the right answer.
