The analogy presented is Sorrow : Tears :: Fatigue : ? This question tests your ability to recognize and apply relationships between words. The first part of the analogy, Sorrow : Tears, establishes a relationship where tears are a physical manifestation or outward sign of the inner emotion of sorrow.
We need to find a word in the options that represents a physical manifestation or sign of the inner state of fatigue.
* Blood: Blood is not a direct physical manifestation of fatigue; it doesn't represent the outward sign of being tired.
* Lymph: Lymph isn't directly related to tiredness.
* Perspiration: Perspiration (sweat) can be caused by physical exertion, which often leads to fatigue. It is a visible sign of physical activity and therefore can be related to fatigue.
* Catarrh: Catarrh involves the inflammation of a mucous membrane and is associated with congestion rather than fatigue.
Therefore, the correct answer is Perspiration because just as tears are an outward sign of sorrow, perspiration can be a sign of physical exertion and therefore, related to fatigue.
