In the analogy “Foresight : anticipation :: Insomnia : ____”, which option best expresses the related meaning of the second word pair?

Introduction / Context:
This analogy tests vocabulary and synonym recognition. The first pair “Foresight : anticipation” links two words with very similar meanings. To complete the analogy, you must match “Insomnia” with the option that is closest in meaning. These kinds of questions are common in verbal ability sections and help measure your command of English word relationships.

Given Data / Assumptions:

• First pair: Foresight and anticipation.
• Second pair: Insomnia and an unknown option.
• Options: gems, sleeplessness, iron, diamond, fatigue.
• We treat the first pair as near synonyms.

Concept / Approach:
Foresight and anticipation both refer to the ability or act of seeing or planning ahead before something happens. So the relationship is one of synonymy. Insomnia is a medical or psychological condition in which a person has persistent difficulty in sleeping. The word in the options that expresses this meaning most directly is sleeplessness. Therefore, we must pair insomnia with sleeplessness to mirror the synonym relationship.

Step-by-Step Solution:

Step 1: Confirm the relation in the first pair. Foresight means looking ahead or planning in advance, and anticipation means expecting or looking forward to something. Step 2: Conclude that the first pair links two words of similar meaning. Step 3: Define insomnia. It is a condition where a person finds it hard to fall asleep or stay asleep. Step 4: Look at the options and identify which word captures the idea of not sleeping. Sleeplessness clearly matches this meaning. Step 5: Check that no other option gives a better or equally strong synonym for insomnia.

Verification / Alternative check:
Compare each option. Gems and diamond both relate to precious stones and have no connection with sleep. Iron is a metal, completely unrelated. Fatigue is a feeling of tiredness, which can be caused by insomnia but is not the same as insomnia itself. Sleeplessness directly means the state of being unable to sleep. Therefore the best parallel to the synonym pair is insomnia paired with sleeplessness.

Why Other Options Are Wrong:
Gems, iron, and diamond are objects, not conditions, and they do not belong to the same semantic field as insomnia. Fatigue is a consequence or symptom that can arise from insomnia, but it is not a synonym. The analogy requires a direct meaning relationship similar to foresight and anticipation, which only sleeplessness provides.

Common Pitfalls:
A common error is to pick a related effect rather than a true synonym, such as choosing fatigue because people with insomnia often feel tired. However, the analogy is about meaning similarity, not cause and effect. When tackling these questions, first label the relationship in the given pair as synonym, antonym, part whole, or cause effect, and then enforce that same relationship strictly in the second pair.

Final Answer:
The correct completion is that insomnia stands to sleeplessness in the same way that foresight stands to anticipation.
