Meaning: A 'table' is a piece of furniture with a flat top and one or more legs, used for placing items on, such as a laptop in this context.

Wrong options:

• sideboard: A 'sideboard' is a piece of furniture used for storing dishes and serving food, not typically associated with a bedside setting, making it contextually inappropriate here.
• wardrobe: A 'wardrobe' is a tall cupboard used for storing clothes, which does not fit the context of placing a laptop, as it is not a flat surface.
• commode: A 'commode' refers to a piece of furniture that can serve as a toilet or a storage unit, which is not suitable for placing a laptop.

Correct answer: lease

Explanation: The term 'lease' is appropriate as it refers to a legal agreement for renting property, which fits the context of a new arrangement for the rainforests. It aligns with the idea of a new 'lease of life' indicating a fresh opportunity or revival.

Meaning: A 'lease' is a contract granting use or occupation of property during a specified period in exchange for a specified rent.

Wrong options:

• treaty: A 'treaty' is a formal agreement between countries, which does not fit the context of a new arrangement for the rainforests.
• contract: A 'contract' is a broader term for any agreement, but it lacks the specific connotation of renewal or revival that 'lease' conveys in this context.
• mortgage: A 'mortgage' is a loan specifically for purchasing property, which does not apply to the context of providing a new life for rainforests.

Correct answer: marches

Explanation: The verb 'marches' fits well as it conveys a sense of progression or movement over time, which aligns with the context of time moving forward. It is grammatically correct and contextually appropriate in this sentence.

Meaning: 'Marches' means to move forward steadily and purposefully, often used to describe the passage of time in a metaphorical sense.

Wrong options:

• strides: 'Strides' implies taking long steps, which does not convey the continuous and steady movement of time as effectively as 'marches.'
• strolls: 'Strolls' suggests a leisurely walk, which does not fit the serious tone of time's progression in this context.
• walks: 'Walks' is too general and lacks the connotation of determined movement that 'marches' provides.

Correct answer: deteriorates

Explanation: The word 'deteriorates' is the most suitable choice as it indicates a decline in quality or condition, which is contextually relevant to eyesight due to prolonged computer use. It fits grammatically and logically within the sentence structure.

Meaning: 'Deteriorates' means to become progressively worse, particularly in terms of health or quality, which is applicable to eyesight in this context.

Wrong options:

• debilitates: 'Debilitates' means to weaken or impair, but it is more severe and does not fit the context of gradual decline in eyesight as well as 'deteriorates.'
• destroys: 'Destroys' implies complete ruin, which is too extreme for the context of eyesight decline; it suggests an irreversible condition.
• disintegrates: 'Disintegrates' suggests breaking apart into pieces, which is not an appropriate description for the gradual decline of eyesight.

Correct answer: turn

Explanation: The verb 'turn' is appropriate here as it conveys the action of rotating or changing position, which fits the idiomatic expression 'turn in his grave,' indicating disapproval or unrest. It is grammatically correct and contextually relevant.

Meaning: 'Turn' in this context means to rotate or shift position, often used in the phrase to express that someone would be upset about current events.

Wrong options:

• move: 'Move' is too vague and does not capture the specific idiomatic meaning of 'turn in his grave.'
• roll: 'Roll' suggests a physical action that does not align with the idiomatic expression, which is more about emotional response than physical movement.
• swivel: 'Swivel' implies a pivoting motion, which does not fit the idiomatic context of expressing disapproval or unrest.
