Meaning: 'Whose' is used to indicate possession, meaning 'belonging to whom.' In this case, it shows that the life being discussed belongs to Carl.

Wrong options:

• which: The word 'which' is a relative pronoun used for non-defining clauses, but it does not indicate possession, making it unsuitable here.
• who: The word 'who' is a subject pronoun and does not convey possession, thus it does not fit the grammatical structure needed in this context.
• when: The word 'when' is an adverb indicating time, which does not relate to the possessive context of the sentence.

Correct answer: benefits

Explanation: The word 'benefits' fits contextually as it refers to the positive outcomes of being positive, which is the main theme of the film. Grammatically, it is a plural noun that aligns with the structure of the sentence, which discusses multiple advantages.

Meaning: 'Benefits' refers to the advantages or positive effects that result from a particular action or situation, in this case, being positive.

Wrong options:

• measures: The word 'measures' refers to actions taken to achieve something, which does not align with the context of discussing positive outcomes.
• branches: The word 'branches' typically refers to parts of a tree or divisions of a subject, which does not fit the context of discussing positivity.
• peaks: The word 'peaks' refers to the highest points, which does not relate to the advantages of being positive.

Correct answer: picky

Explanation: The word 'picky' accurately describes someone who is very selective or hard to please, fitting the context of Carl's character. It is an adjective that aligns with the description of his personality in the sentence.

Meaning: 'Picky' means being very particular about what one likes or dislikes, indicating that Carl is difficult to satisfy.

Wrong options:

• punctual: The word 'punctual' describes someone who is on time, which does not relate to being hard to please.
• extrovert: The word 'extrovert' refers to someone who is outgoing and sociable, which contrasts with the idea of being hard to please.
• conscientious: The word 'conscientious' describes someone who is diligent and careful, which does not fit the context of Carl's personality.

Correct answer: ends up

Explanation: The phrase 'ends up' indicates a final outcome or conclusion, which fits the context of Carl's transformation into a positive person. It is a phrasal verb that conveys the idea of arriving at a state after a process, aligning well with the narrative of the film.

Meaning: 'Ends up' means to eventually reach a particular state or condition, in this case, becoming a positive person.

Wrong options:

• puts off: The phrase 'puts off' means to delay or postpone, which does not fit the context of Carl's transformation into positivity.
• falls for: The phrase 'falls for' typically means to become infatuated with someone, which does not relate to the theme of personal transformation.
• goes through: The phrase 'goes through' implies experiencing something, but it does not convey the finality of becoming a positive person.

Correct answer: numerous

Explanation: The word 'numerous' fits contextually as it describes a large quantity of funny scenes, aligning with the positive sentiment of the film. Grammatically, it is an adjective that correctly modifies the noun 'scenes' in the plural form.

Meaning: 'Numerous' means many or a lot of, indicating that there are many funny scenes in the film.

Wrong options:

• ridiculous: The word 'ridiculous' implies something absurd or laughable, which does not convey the quantity of funny scenes.
• irritating: The word 'irritating' describes something that causes annoyance, which contradicts the positive nature of the film's humor.
• convenient: The word 'convenient' refers to something that is easy to use or suitable, which does not relate to the quantity of funny scenes.
