Find the correct alternative from the following: Ocean : Pacific : : Island : ?

The analogy is about rank within a category. The Pacific is the largest of the world's oceans, so the matching term is the largest island, which is Greenland. Greenland covers about 2.1 million sq km and lies mostly north of the Arctic Circle. It is also the largest island that is not a continent, which is the standard way to rank islands in Geography texts.

Why the others fail:

• Ireland is a real island, but it is only about the 20th largest, so it does not fit the 'largest' relation.
• Netherland is not an island. The Netherlands is a European country on the mainland, which makes it a distractor based on the name.
• Borneo is an island and a common distractor, but it is the third largest island, after Greenland and New Guinea.

Core concept: superlatives in analogy questions. Pair the given term with its superlative counterpart in the same category, and verify the ranking. This kind of ranking knowledge (largest island, largest ocean, highest mountain) is useful for Prelims Geography and for Mains answers on physical features.

Trap: Aspirants pick Borneo because it is famous, or go to Greenland only after confusing Australia's status. Check the superlative carefully.
