Meaning: 'Those' refers to specific items or people that have been previously mentioned or are known to the speaker and listener.

Wrong options:

• whose: 'Whose' is a possessive pronoun and does not fit the context of identifying types of cancers.
• which: 'Which' is a relative pronoun used to introduce a clause but does not serve to specify the cancers in this context.
• them: 'Them' is an object pronoun and does not grammatically or contextually fit as it does not specify the cancers.

Correct answer: diagnosed

Explanation: The word 'diagnosed' is the correct choice as it refers to individuals who have been identified as having cancer. It fits grammatically in the past participle form, indicating a completed action relevant to the subject of the sentence.

Meaning: 'Diagnosed' means having been identified with a particular disease or condition, in this case, cancer.

Wrong options:

• claimed: 'Claimed' implies a statement or assertion that may not be verified, which does not fit the medical context of identifying cancer.
• exposed: 'Exposed' refers to being subjected to something harmful, which does not accurately describe individuals with cancer.
• confronted: 'Confronted' suggests facing a challenge or difficulty, which is not the appropriate term for someone who has been identified as having cancer.

Correct answer: appears

Explanation: The word 'appears' is suitable as it indicates a seeming or apparent condition, which aligns with the context of discussing findings that are not definitively proven. It fits grammatically as a verb in the present tense, suggesting an ongoing observation.

Meaning: 'Appears' means to seem or to give the impression of being something, in this case, suggesting a relationship between exercise and cancer risk.

Wrong options:

• demands: 'Demands' implies a requirement or necessity, which does not fit the context of suggesting a relationship.
• permits: 'Permits' indicates allowance or permission, which does not align with the context of discussing findings or observations.
• suggests: 'Suggests' is close but does not convey the same level of apparent certainty as 'appears' in this context.

Correct answer: longevity

Explanation: The word 'longevity' is appropriate as it refers to a long duration of life, which fits the context of discussing health benefits related to exercise. It is a noun that aligns with the overall theme of health and survival.

Meaning: 'Longevity' means a long life or existence, particularly in the context of health and well-being.

Wrong options:

• conformity: 'Conformity' refers to compliance with standards or norms, which does not relate to health benefits.
• margin: 'Margin' typically refers to a boundary or edge, which does not fit the context of health benefits.
• terminal: 'Terminal' refers to an end or limit, often used in a negative context regarding life expectancy, which contradicts the positive implications of health benefits.

Correct answer: incentive

Explanation: The word 'incentive' is fitting as it refers to a motivation or encouragement to act, which aligns with the context of promoting exercise for health benefits. It is a noun that conveys the idea of a reason to maintain an exercise habit.

Meaning: 'Incentive' means something that motivates or encourages someone to do something, in this case, to maintain an exercise routine.

Wrong options:

• status: 'Status' refers to a social or professional position, which does not relate to motivation for exercise.
• policy: 'Policy' refers to a course of action adopted by an organization, which does not fit the personal context of maintaining an exercise habit.
• pursuit: 'Pursuit' implies the act of chasing or striving for something, which does not convey the same motivational aspect as 'incentive.'
