Meaning: 'Healing' refers to the process of making or becoming sound or healthy again, particularly in an emotional context.

Wrong options:

• curing: Curing implies a complete eradication of a disease or condition, which does not fit the broader emotional context here.
• treating: Treating suggests managing a condition rather than promoting overall well-being, making it less suitable in this context.
• improving: Improving indicates enhancement but lacks the specific connotation of recovery associated with 'healing'.

Correct answer: sign

Explanation: The word 'sign' is appropriate as it indicates a symbol or indication of something, in this case, weakness. It fits grammatically as a noun that complements the phrase, and contextually, it aligns with societal perceptions of emotional expression.

Meaning: 'Sign' means an indication or evidence of something, here referring to the perception of crying as a weakness.

Wrong options:

• hint: Hint suggests a subtle indication, which does not convey the strong implication of weakness present in the context.
• symbol: Symbol implies a representation, but 'sign' is more direct in indicating weakness in this context.
• feature: Feature suggests a characteristic, which does not capture the negative connotation of weakness as effectively as 'sign'.

Correct answer: rid

Explanation: The word 'rid' fits grammatically as a verb that indicates the action of removing something undesirable. Contextually, it aligns with the idea of eliminating toxic chemicals from the body, which is the focus of the sentence.

Meaning: 'Rid' means to free or remove someone or something from a burden or unwanted condition.

Wrong options:

• release: Release implies letting go but does not convey the active removal aspect that 'rid' does.
• loosen: Loosen suggests making something less tight, which does not fit the context of eliminating toxins.
• expel: Expel implies forceful removal, which is too strong for the context of the body's natural processes.

Correct answer: waste

Explanation: The word 'waste' is suitable as it refers to unwanted or unusable materials, fitting grammatically as a noun that completes the phrase. Contextually, it aligns with the idea of toxic substances that the body needs to eliminate.

Meaning: 'Waste' refers to materials that are no longer needed or useful, particularly in a biological context.

Wrong options:

• rubbish: Rubbish is more informal and implies trash or garbage, which does not fit the scientific tone of the passage.
• leftovers: Leftovers suggest remaining food, which is not applicable in the context of bodily chemicals.
• remains: Remains imply what is left after a process, which does not specifically denote unwanted substances like 'waste' does.

Correct answer: consider

Explanation: The word 'consider' fits grammatically as a verb that introduces a thought or opinion. Contextually, it aligns with the idea of reflecting on the popularity of emotional films, making it a suitable choice.

Meaning: 'Consider' means to think about something carefully, especially in making a decision or forming an opinion.

Wrong options:

• remark: Remark implies a casual comment, which does not convey the depth of thought suggested by 'consider'.
• distinguish: Distinguish suggests identifying differences, which does not fit the context of evaluating popularity.
• regard: Regard implies a level of respect or consideration but lacks the active thought process indicated by 'consider'.

Correct answer: called

Explanation: The word 'called' is appropriate as it serves as a verb that indicates what something is named. It fits grammatically and contextually, as it directly relates to how the films are referred to in society.

Meaning: 'Called' means to name or refer to something in a particular way.

Wrong options:

• named: Named is a synonym but is less commonly used in this context, making 'called' more natural in everyday language.
• entitled: Entitled suggests a formal title, which does not fit the casual naming convention of films.
• subtitled: Subtitled refers to adding text to a film, which is unrelated to the naming of the films themselves.
