Meaning: 'Unlike' means 'not similar to' or 'dissimilar from,' indicating that the Galapagos Islands are different from many other islands in terms of their preservation from globalization.

Wrong options:

• Due to: 'Due to' suggests a reason or cause, which does not fit the context of contrasting the Galapagos with other islands.
• Despite: 'Despite' indicates a concession but does not establish a direct contrast in the same way 'Unlike' does, making it less suitable here.
• Instead of: 'Instead of' implies a substitution, which does not align with the intended meaning of contrasting the Galapagos with other islands.

Correct answer: teem

Explanation: The verb 'teem' means to be full of or to swarm with, which fits perfectly in the context of describing the Galapagos Islands as being rich in life. It is grammatically correct and contextually appropriate, as it conveys the abundance of unique species present on the islands.

Meaning: 'Teem' means to be filled or overflowing with something, in this case, life, indicating that the Galapagos Islands are vibrant ecosystems.

Wrong options:

• link: 'Link' implies a connection or relationship, which does not fit the context of describing the abundance of life.
• fill: 'Fill' suggests making something full but lacks the connotation of abundance that 'teem' provides.
• restore: 'Restore' means to bring something back to a former condition, which does not apply to the context of describing the current state of life on the islands.

Correct answer: restricted

Explanation: The word 'restricted' indicates that access to certain areas is limited, which is contextually relevant as it aligns with the conservation efforts mentioned earlier. It fits grammatically as it describes the management of tourism in a way that protects the islands' ecology.

Meaning: 'Restricted' means limited or controlled, indicating that tourism is carefully managed to protect the islands' environment.

Wrong options:

• stretched: 'Stretched' implies extending something beyond its limits, which does not fit the context of managing tourism.
• rid: 'Rid' means to remove or eliminate, which does not apply to the context of managing tourism access.
• verified: 'Verified' means confirmed or validated, which does not relate to the management of tourism in this context.

Correct answer: between

Explanation: The preposition 'between' is used to indicate a relationship involving two distinct entities, which is appropriate here as it refers to the balance between showcasing wonders and safeguarding treasures. It fits grammatically and contextually, emphasizing the dual focus of the islands' management.

Meaning: 'Between' refers to the space or relationship separating two entities, in this case, the showcasing of wonders and the safeguarding of ecological treasures.

Wrong options:

• upon: 'Upon' suggests a position or condition but does not convey the relationship between the two concepts as effectively as 'between.'
• toward: 'Toward' indicates direction but does not fit the context of balancing two distinct aspects.
• among: 'Among' is used for three or more entities, making it grammatically incorrect in this context where only two aspects are being compared.

Correct answer: share

Explanation: The verb 'share' is appropriate as it indicates a mutual relationship between the islanders and the diverse species, fitting grammatically and contextually. It emphasizes the coexistence of humans and wildlife on the islands, aligning with the overall theme of well-being and ecological balance.

Meaning: 'Share' means to have something in common with others, indicating that islanders and species coexist in the same environment.

Wrong options:

• engage: 'Engage' implies active participation, which does not accurately describe the relationship between islanders and species in this context.
• regard: 'Regard' means to consider or think of, which does not convey the mutual relationship implied in the sentence.
• live: 'Live' suggests existence but lacks the connotation of shared space and coexistence that 'share' provides.
