The analogy establishes a relationship between a specific territory or city and the larger entity or city that contains it. Hong Kong is a territory associated with China, and similarly, the Vatican City is an independent city-state located entirely within the city of Rome, Italy.

This analogy explores the relationship between types of thoroughfares. A lane is a smaller or narrower version of a street. Similarly, an avenue is often categorized as a specific type of road, typically wider or more prominent. The analogy relies on the hierarchical classification of urban infrastructure, where one term represents a broader category and the other represents a specific or related sub-category.

Newspapers, hoardings (billboards), and television are all distinct channels used to disseminate information to the public. Collectively, these platforms are classified under the umbrella term 'media', which encompasses various forms of mass communication used to reach large audiences through print, digital, or visual means.

The relationship in 'Iron : Silver : Gold' is that all three items are specific examples belonging to the category of metals. Similarly, 'Wheat' and 'Barley' are specific examples belonging to the category of 'Cereal'. This analogy identifies a group of items followed by their broader classification.

The relationship here involves an action that damages or diminishes a quality. Slander is a false statement that damages a person's reputation or honour. Option A maintains this relationship by linking the act of slander to the potential damage or loss of one's integrity.

Lions, tigers, and leopards are all members of the Felidae family. They share the biological classification of being carnivores, meaning their diet consists primarily of meat obtained through hunting or scavenging other animals.

The relationship defined here is between an institution and the primary individual it serves. A college is an institution where a student goes to receive education. Similarly, a hospital is an institution where a patient goes to receive medical care, making 'patient' the correct counterpart in this analogy.

The relationship is defined by the primary purpose or function of an institution. A court is established to provide justice, while the fundamental purpose of a school is to provide education. Therefore, education is the correct functional counterpart.

This analogy relates a destructive event to its primary cause or associated phenomenon. Annihilation can be caused by fire, while a cataclysm, often defined as a violent upheaval or disaster, is historically and metaphorically associated with a great flood.

This analogy explores scientific fields of study. Botany, Zoology, and Cardiology are specific branches of science. The provided answer key indicates that 'Pedology' is the intended answer, although the logic for this specific selection within the provided options may vary based on the classification criteria used in the source material.
