A.I. Explanation:

Correct answer: blown

Explanation: The word 'blown' fits grammatically as the past participle of 'blow,' which is used here in the idiomatic expression 'blown out of the water,' meaning to be completely disproven or invalidated. This aligns with the context of the sentence, which discusses how new findings have negated previous advice.

Meaning: 'Blown' in this context means to be completely defeated or disproven, especially in a surprising or dramatic way.

Wrong options:

• shattered: 'Shattered' implies breaking into pieces, which does not fit the idiomatic expression used here and suggests a physical action rather than a conceptual one.
• torn: 'Torn' suggests being ripped apart, which does not convey the same meaning as 'blown out of the water' and is not idiomatic in this context.
• exploded: 'Exploded' implies a sudden burst or increase, which does not align with the intended meaning of disproving or invalidating advice.

Correct answer: there

Explanation: The word 'there' is used correctly as a pronoun indicating existence, fitting grammatically and contextually to introduce the clause about the connection between cholesterol content and production in the blood.

Meaning: 'There' refers to the existence of something, in this case, indicating that a connection does or does not exist.

Wrong options:

• this: 'This' is a demonstrative pronoun that refers to something specific and does not fit the context of introducing a general statement about existence.
• that: 'That' is also a demonstrative pronoun but implies a specific reference, which does not suit the context of stating the existence of a connection.
• then: 'Then' is an adverb indicating time or sequence, which does not fit grammatically or contextually in this sentence.

Correct answer: flow

Explanation: The word 'flow' is appropriate here as it refers to the movement of cholesterol in the blood, fitting grammatically as a noun that describes the process being discussed in the context of the sentence.

Meaning: 'Flow' refers to the movement or circulation of something, in this case, cholesterol in the bloodstream.

Wrong options:

• cancel: 'Cancel' means to annul or invalidate, which does not fit the context of describing how cholesterol moves in the blood.
• stream: 'Stream' could refer to a flow but is less commonly used in this context and does not convey the same medical or biological connotation as 'flow.'
• course: 'Course' can refer to a path or direction but is less precise in this context compared to 'flow,' which directly relates to the movement of blood.

Correct answer: cumulative

Explanation: The word 'cumulative' fits grammatically as an adjective describing the effects of various lifestyle choices, indicating that these effects build up over time, which is contextually relevant to the discussion of diet and lifestyle factors.

Meaning: 'Cumulative' means increasing or growing by accumulation or successive additions, referring to the combined effects of lifestyle choices.

Wrong options:

• unfield: 'Unfield' is not a standard English word and does not convey any relevant meaning in this context.
• assembled: 'Assembled' implies putting together, which does not accurately describe the nature of effects that accumulate over time.
• motley: 'Motley' refers to a varied or diverse mixture, which does not fit the context of describing the combined effects of lifestyle choices.
