The word 'incredulous' means unwilling or unable to believe something; it describes a state of skepticism or disbelief. It is not synonymous with 'unreliable,' but among the given options, none are true synonyms of 'incredulous.' The options 'Dishonest,' 'Honest,' and 'Reliable' do not relate to disbelief or skepticism. 'Unreliable' means not trustworthy, which is unrelated to the meaning of 'incredulous.' Therefore, none of the options are correct synonyms. The question options should ideally include words like 'skeptical,' 'disbelieving,' or 'doubtful' as correct synonyms. Since the original options do not contain a correct synonym, the question is flawed. However, based on the options given, 'Unreliable' (D) is not a synonym of 'incredulous.'

The antonym of 'parsimony' (extreme unwillingness to spend money) is 'generosity' (willingness to give or spend freely). The other options do not relate to the meaning of parsimony.

Lethargy means a state of sluggishness or lack of energy, and 'Laxity' refers to looseness or lack of strictness, which can be related to a lack of energy or alertness, making it the closest synonym among the options. The other options do not relate to lethargy.

The word 'fodder' typically means material, especially raw material used for a particular purpose, such as food for livestock or material for a specific use. Among the options, 'material' is the closest in meaning to 'fodder'.

The word 'sartorial' relates to tailoring, clothes, or style of dress, implying something stylish or related to fashion. Among the options, 'Inelegant' is the best antonym because it directly contrasts with the refined or stylish connotation of 'sartorial.' 'Homespun' means simple or homemade, which can be related but does not directly oppose sartorial style as clearly as 'inelegant.' Therefore, 'Inelegant' is a more precise antonym.

The word 'prevaricate' means to speak or act in an evasive way, often to avoid telling the truth, which is closely related to 'lie'. Therefore, 'lie' is the correct synonym among the options provided.

The analogy 'Joke : Laughter' shows a cause and effect or stimulus and response relationship, where a joke typically causes laughter. Similarly, 'Cry : Sorrow' represents a cause and effect relationship where crying is a response to sorrow. Option D ('Miracle : Surprise') is related but less direct, as not all miracles necessarily cause surprise. Therefore, A is the best answer.

The analogy compares a small piece of a substance to the whole material it comes from. A grain is a small particle of salt, just as a chip is a small piece broken off from glass. Therefore, 'chip: glass' correctly parallels 'grain: salt'.

Paragraph 3 suggests that light can barely reveal a black hole because black holes do not emit light and are detected indirectly by their effects on nearby matter and light. This supports option B as the correct answer.

The word 'garbled' means distorted or mixed up, so its antonym is 'unscramble,' which means to make clear or restore to the original form. Therefore, option B is correct.
