Verbal Analogies

 Cricket is played on a pitch and boxing is played in the ring.

 The colour of blood is red and the colour of grass is green.

The analogy shows state changes: melting converts solid to liquid, so the analogous operation should convert liquid back to solid. Freezing does exactly this - it's the reverse process of melting. 'Cold' is the cause, not the result. 'Ice' is a specific substance, not the general state. 'Air' is unrelated to state change.

The relationship is content:storage medium. Videos are commonly stored on cassettes (like VHS tapes). Similarly, computer data and software are commonly stored on compact discs (CDs). The other options (edit, files, bytes) are related to computers but not storage media like cassettes are for videos.

A quarrel is a small-scale conflict that can escalate into war (large-scale conflict). Similarly, being unhappy is a mild negative state that can escalate to sadness (a more intense negative state). The analogy follows: lesser negative: greater negative.

Darwin is famous for the theory of Evolution. Similarly, Archimedes is famous for the principle of Buoyancy (Archimedes' principle). The relationship is 'scientist : their major discovery/theory'. Friction and Lubrication are related but not tied to a single scientist, while Liquid is too general.

Push and Pull are opposite actions - one moves away, one brings closer. Similarly, Throw (send away) and Pick (take/grab) represent the same directional relationship. Throw sends an object away, while Pick brings it closer or takes it. Collect is similar but doesn't capture the directional contrast.

A Poodle is a specific breed of dog - the relationship is 'specific : general category'. Similarly, a Moose is a specific type of Deer. Duck, Donkey, and Fowl are completely different animals and don't fit the category relationship.

Naphthalene is derived from Coal tar - it's a compound obtained from coal tar distillation. Similarly, Dyes can be derived from Petroleum (petroleum-based dyes). The relationship is 'product : source'. Oils and Chemicals are related but not the primary source, while Carbon is an element, not a source.

A Conference is presided over by a Chairman. Similarly, a Newspaper is overseen by an Editor. The relationship is 'organization/institution : person in charge'. A Reporter collects news but doesn't oversee the newspaper, while Distributer and Painter are unrelated to the organizational hierarchy.

 Oven is used to serve the meals hot; referigerator is used to serve the meals cold.

A forest is a collection or group of many trees. Similarly, a lawn is made up of many grass plants growing together. The relationship is 'individual unit → collection/aggregate of those units.'

A bank is the land alongside a river. Similarly, a coast is the land alongside a sea or ocean. The relationship is 'land feature : body of water it borders/edges.'

 The correct answer is weapon. Malaria is a disease and disease describes what Malaria is. Therefore, weapon descibes what a spear is.

Matricide is the killing of one's mother (a specific type of killing). Homicide is the killing of a human being (the general category). The relationship is 'specific type : general category.' 'Matricide' comes from Latin 'mater' (mother), just as 'homicide' comes from 'homo' (human).
