Meaning: 'Original' refers to being unique or the first of its kind, highlighting the speaker's individuality in her inability to refuse requests.

Wrong options:

• innovative: 'Innovative' suggests creativity or new ideas, which does not directly relate to the speaker's inability to say no, making it contextually inappropriate.
• first: 'First' implies a ranking or order, which does not convey the intended meaning of uniqueness in this context.
• foremost: 'Foremost' indicates being the most important or leading, which does not accurately describe the speaker's situation as someone who can't refuse.

Correct answer: exhausted

Explanation: The word 'exhausted' fits well as it describes the speaker's state after not managing her time effectively, aligning with the context of feeling drained after work.

Meaning: 'Exhausted' means extremely tired or worn out, reflecting the speaker's physical and mental state after her work habits.

Wrong options:

• apathetic: 'Apathetic' means lacking interest or enthusiasm, which does not accurately describe the speaker's condition of being tired from overwork.
• gruelling: 'Gruelling' describes something extremely tiring or demanding, but it does not fit as a state of being; it describes an action or experience instead.
• spent: 'Spent' means used up or exhausted, but it is less commonly used in this context compared to 'exhausted,' which is more precise.

Correct answer: sufficient

Explanation: The word 'sufficient' fits grammatically and contextually as it indicates an adequate amount of rest needed for the speaker to function well, aligning with the overall message of the sentence.

Meaning: 'Sufficient' means enough or adequate, emphasizing the necessity of having enough rest to maintain well-being.

Wrong options:

• severe: 'Severe' implies something harsh or intense, which does not relate to the amount of rest needed and is contextually inappropriate.
• acceptable: 'Acceptable' refers to something that meets a standard but does not convey the idea of adequacy in terms of rest, making it less fitting here.
• minimal: 'Minimal' suggests a very small amount, which contradicts the need for adequate rest, thus making it unsuitable.

Correct answer: equivalent

Explanation: The word 'equivalent' fits perfectly as it indicates that 20 minutes of meditation serves the same restorative purpose as a full night's sleep, aligning with the context of comparing two forms of rest.

Meaning: 'Equivalent' means equal in value, function, or meaning, highlighting the speaker's belief in the restorative power of meditation.

Wrong options:

• compatible: 'Compatible' means able to exist or work together, which does not convey the idea of equivalence in restorative effects, making it contextually incorrect.
• alike: 'Alike' suggests similarity but lacks the precise meaning of equal value, thus not fitting the context of comparing meditation to sleep.
• proportional: 'Proportional' refers to a relationship in size or amount, which does not accurately describe the equivalence of meditation to sleep, making it unsuitable.
