Difficulty: Easy
Correct Answer: Insomnia
Explanation:
Introduction / Context:
This question checks your understanding of medical and psychological terms that are often used in general English. Sleep problems are commonly discussed in newspapers, health articles, and conversations. The word that describes a prolonged inability to sleep is important not only for exams but also for everyday awareness of mental and physical health issues.
Given Data / Assumptions:
Concept / Approach:
Insomnia is the medical term for difficulty falling asleep, staying asleep, or both, over a significant period. It causes tiredness, lack of concentration, and various health issues. Amnesia is loss of memory, utopia is an imagined perfect place or society, and nausea is the feeling of sickness with an urge to vomit. Therefore, only insomnia corresponds to prolonged sleep difficulties.
Step-by-Step Solution:
Verification / Alternative check:
You can verify the choice by forming example sentences. "He has been suffering from insomnia for months" makes sense and is commonly heard. If you replace insomnia with amnesia, utopia, or nausea, the sentence becomes illogical or changes meaning completely. This language based check confirms that insomnia is the right answer.
Why Other Options Are Wrong:
Common Pitfalls:
Students may confuse medical sounding terms simply because they are unfamiliar. To avoid mistakes, it is useful to learn such words in groups and connect each with a simple example sentence. That way, you immediately associate insomnia with sleep problems, amnesia with memory, and nausea with stomach upset.
Final Answer:
The correct one-word term for "prolonged inability to sleep" is Insomnia.
