A.I. Explanation:

Correct answer: native

Explanation: The word 'native' correctly describes the vanilla plant as originating from the Americas, fitting grammatically as an adjective that modifies 'plant' and contextually indicating its natural habitat.

Meaning: 'Native' means originating or produced in a particular place, in this case, referring to the vanilla plant being originally from the Americas.

Wrong options:

• resident: 'Resident' implies a person or animal living in a place, which does not fit the context of a plant's origin.
• local: 'Local' suggests something pertaining to a specific area but lacks the implication of origin that 'native' provides.
• inhabitant: 'Inhabitant' refers to a living being residing in a place, which is not appropriate for describing a plant.

Correct answer: resulting

Explanation: The word 'resulting' indicates that the seed pods are produced as a consequence of the vanilla plant's growth, fitting grammatically as a present participle and contextually linking to the process of pod formation.

Meaning: 'Resulting' means occurring as a consequence or outcome, in this case, referring to the seed pods that come from the vanilla plant.

Wrong options:

• deriving: 'Deriving' suggests obtaining from a source, which does not accurately describe the formation of seed pods as a natural outcome.
• producing: 'Producing' implies an active creation, which is less fitting than 'resulting' in this context where the pods are a natural outcome of growth.
• arising: 'Arising' suggests coming into being but lacks the clarity of consequence that 'resulting' provides.

Correct answer: distinctive

Explanation: The word 'distinctive' accurately describes the unique flavour and fragrance of the vanilla pods, fitting grammatically as an adjective that modifies 'flavour' and contextually emphasizing their special characteristics.

Meaning: 'Distinctive' means having a quality or characteristic that makes something different or unique, in this case, referring to the unique flavour of vanilla.

Wrong options:

• appetising: 'Appetising' refers to food that looks or smells good, which does not specifically convey the uniqueness of the flavour as 'distinctive' does.
• tasteful: 'Tasteful' implies a sense of style or aesthetic, which is not relevant to describing the flavour of vanilla pods.
• potential: 'Potential' refers to the capacity to develop into something in the future, which does not apply to the established flavour of the pods.

Correct answer: shrunk

Explanation: The word 'shrunk' indicates that the beans have reduced in size, fitting grammatically as the past participle of 'shrink' and contextually describing the curing process of the beans.

Meaning: 'Shrunk' means to have become smaller in size, referring to the beans reducing to a fifth of their original size during curing.

Wrong options:

• concentrated: 'Concentrated' implies a focus or intensification, which does not accurately describe the physical size reduction of the beans.
• lessened: 'Lessened' suggests a reduction but is less specific than 'shrunk' regarding size, making it less appropriate in this context.
• sunk: 'Sunk' refers to something that has gone down or submerged, which does not relate to the size reduction of the beans.

Correct answer: caught

Explanation: The word 'caught' is used in the phrase 'caught with failure,' indicating that attempts to grow vanilla in other locations were unsuccessful. It fits grammatically as the past participle of 'catch' and contextually describes being affected by failure.

Meaning: 'Caught' here means to be affected by or to experience a negative result—in this case, repeated failure.

Wrong options:

• resulted: 'Resulted' implies a direct outcome but does not fit the phrasing or convey the idea of being ensnared or stuck in failure.
• hit: 'Hit' suggests a sudden impact or occurrence, not the ongoing struggle described.
• finished: 'Finished' implies completion, not the state of being affected by failure.
